Rail Transit Fasteners: Engineering & OEM Sourcing Guide

Jan. 13, 2024

Rail Transit Fasteners: Engineering & OEM Sourcing Guide

Rail vehicles and railway equipment contain thousands of mechanical interfaces, but they do not all require the same type of fastener.

A permanent aluminum panel joint, removable electrical cabinet cover, interior equipment bracket, threaded mounting point and vibration-exposed bolted assembly represent different engineering problems.

The correct question is therefore not:

“What is the best railway fastener?”

It is:

“Which fastening method is appropriate for this joint, parent material, load, environment, maintenance strategy and railway project requirement?”

JUXIN FASTENERS supplies blind rivets, rivet nuts, lock nuts, screws, bolts, self-clinching fasteners, threaded inserts, 

plastic and nylon fasteners and drawing-based custom components for railway equipment and other industrial OEM applications.

Typical rail-related applications can include:

  • Rail vehicle interior equipment

  • Electrical cabinets

  • Converter cabinets

  • Control equipment

  • Aluminum panels

  • Equipment housings

  • Secondary brackets

  • Access covers

  • Lighting assemblies

  • Cable-management components

  • Equipment modules

  • Other drawing-based rail equipment assemblies

This guide helps design engineers, procurement teams, 

supplier-development engineers and supply-chain managers translate a railway assembly requirement into a technically meaningful fastener specification and RFQ.

Railway Fastener Selection Starts With the Joint, Not the Catalog

“Railway fastener” is not a single engineering category.

A railway vehicle can contain:

  • Permanent joints

  • Removable joints

  • Thin-sheet joints

  • Blind-access joints

  • Threaded joints

  • Mixed-metal joints

  • Polymer components

  • Electrical equipment

  • Vibration-exposed assemblies

  • Maintenance-access interfaces

Each requires a different decision path.

Before choosing the fastener, define:

  1. What does the joint do?

  2. Is it structural, supporting or equipment attachment?

  3. Must it be removable?

  4. Can the installer access both sides?

  5. What are the parent materials?

  6. What are their thicknesses?

  7. What loads act on the joint?

  8. What environmental conditions apply?

  9. How will the fastener be installed?

  10. What validation is required?

This prevents one of the most common sourcing mistakes: selecting a fastener family before the assembly requirements are understood.

Rail Transit Fasteners: Engineering

Step 1: Classify Railway Joint Criticality

Not every fastener used on a train has the same consequence of failure.

A useful initial classification is:

Non-Structural Equipment Attachment

Potential examples include certain:

  • Covers

  • Cable-management components

  • Equipment housings

  • Interior trim components

Selection may focus on:

  • Access

  • Serviceability

  • Installation

  • Environment

  • Equipment load

Secondary Structural or Supporting Assembly

Potential examples include certain:

  • Equipment brackets

  • Panel supports

  • Mounting structures

  • Cabinet supports

Mechanical loading, vibration and fatigue requirements may become more important.

Safety-Critical or Primary Structural Joint

Primary load-bearing, running-gear, crash-critical, braking-related or other safety-critical railway joints require project-specific engineering authority, 

technical specifications and formal validation.

A generic industrial fastener should never be assumed suitable for such an application simply because its dimensions or material appear appropriate.

For these projects, the governing customer drawing and technical requirements should define the sourcing process.

Step 2: Permanent or Serviceable?

Rail vehicles are maintained over long service periods.

Fastener selection should therefore reflect the maintenance strategy.

Permanent Joint

Potential solutions include:

  • Blind rivets

  • Other engineered permanent fastening systems

Typical applications may include suitable:

  • Panels

  • Covers not intended for routine removal

  • Enclosure joints

  • Secondary sheet-metal assemblies

Serviceable Joint

Potential solutions include:

  • Screws and bolts

  • Rivet nuts

  • Self-clinching nuts

  • Threaded inserts

  • Lock nuts

  • Other reusable threaded systems

Typical applications include:

  • Service covers

  • Replaceable equipment

  • Electrical modules

  • Inspection panels

  • Mounting brackets

A fastener that is efficient during vehicle production can become expensive during maintenance if the service strategy was ignored during design.

Step 3: Determine Assembly Access

Access is one of the fastest ways to narrow the fastening options.

Two-Side Access

Where both sides are accessible, engineers may consider:

  • Bolt and nut

  • Screw and separate nut

  • Suitable permanent riveting systems

  • Other conventional mechanical fastening

One-Side Access

Where only one side can be reached, potential solutions include:

  • Blind rivets

  • Blind rivet nuts

  • Preinstalled captive threaded hardware where the manufacturing sequence allows

This is why blind fastening technologies are useful in rail vehicle panels, enclosures and equipment modules.

Railway Fastener Selection Matrix

Mixed-metal jointCompatible material/coating systemHas galvanic corrosion been evaluated?
Removable electrical equipmentRivet nut or captive threaded systemHow many maintenance cycles are expected?
Custom interfaceDrawing-based fastenerWhat must be validated before production?

This matrix is a decision framework rather than a substitute for project-specific engineering.

Blind Rivets for Rail Vehicle and Railway Equipment Assemblies

A blind rivet creates a permanent mechanical joint and can be installed where access is available from only one side.

Potential railway applications include suitable:

  • Interior panels

  • Equipment housings

  • Electrical enclosures

  • Covers

  • Secondary brackets

  • Lightweight sheet-metal assemblies

Important selection parameters include:

  • Rivet diameter

  • Grip range

  • Head style

  • Rivet body material

  • Mandrel material

  • Parent materials

  • Hole diameter

  • Individual sheet thicknesses

  • Total joint thickness

  • Blind-side clearance

  • Mechanical requirements

  • Environmental exposure

  • Installation tooling

The correct blind rivet cannot be selected from diameter alone.

Rail Transit Fasteners: Engineering

Grip Range Is a Joint Parameter

For blind rivets, the engineer must consider the complete material stack.

For example:

Aluminum panel + bracket + reinforcement = total grip condition

If the rivet is outside its intended grip range, the blind-side formation and joint condition may become inconsistent.

Potential consequences include:

  • Incomplete formation

  • Poor clamping

  • Parent-sheet deformation

  • Installation variation

Procurement should therefore include the complete material thickness stack in the RFQ.

Thin Sheet and Pull-Through

A stronger rivet does not necessarily create a stronger thin-sheet joint.

In some assemblies, the parent material becomes the limiting component.

A rivet can potentially pull through or deform the surrounding sheet before the fastener itself reaches its nominal capability.

Relevant variables include:

  • Parent material

  • Sheet thickness

  • Hole diameter

  • Rivet diameter

  • Head diameter

  • Edge distance

  • Load direction

This is particularly important for lightweight aluminum assemblies.

Rivet Nuts for Railway Thin-Sheet Assemblies

A blind rivet nut creates a reusable internal thread in suitable sheet material.

It is particularly useful where:

  • The parent sheet is too thin for sufficient direct thread engagement

  • Backside access is restricted

  • A removable component is required

  • A loose nut is undesirable

Potential applications include:

  • Electrical cabinets

  • Equipment modules

  • Interior equipment brackets

  • Access panels

  • Mounting plates

  • Serviceable assemblies

JUXIN FASTENERS supplies rivet nuts in materials and configurations including:

  • Carbon steel

  • Stainless steel

  • Aluminum

  • Round body

  • Round knurled body

  • Hex body

  • Closed-end configurations

  • Various applicable head styles

Final selection should follow the actual joint requirements.

Why Thread Size Is Not Enough for a Rivet Nut RFQ

A request such as:

“Please quote M6 stainless steel rivet nuts.”

is incomplete for engineering review.

The supplier also needs information such as:

  • Parent material

  • Sheet thickness

  • Grip range

  • Hole geometry

  • Head style

  • Body style

  • Pull-out requirement

  • Spin-out or torque-out requirement

  • Mating screw torque

  • Environmental requirement

Two M6 rivet nuts can behave very differently in the same railway panel.

Rivet Nut Spin-Out

Spin-out occurs when the installed rivet nut rotates in the parent material during screw tightening or removal.

Factors can include:

  • Body geometry

  • Knurling

  • Hex geometry

  • Hole size

  • Parent material

  • Sheet thickness

  • Installation setting

  • Applied tightening torque

Where anti-rotation performance matters, it should be defined as an installed-joint requirement rather than inferred from product appearance.

Rivet Nut Pull-Out

Pull-out behavior depends on the interaction between the insert and parent material.

Relevant factors include:

  • Parent material strength

  • Sheet thickness

  • Hole condition

  • Rivet nut geometry

  • Installation quality

  • Axial loading

A higher-strength rivet nut cannot compensate indefinitely for a weak or very thin parent sheet.

Lock Nuts for Railway Threaded Joints

Rail equipment can experience vibration, shock, thermal cycling and repeated service.

However, the phrase “vibration-resistant nut” does not define why a joint might loosen.

Threaded-joint behavior can depend on:

  • Initial preload

  • Joint stiffness

  • Transverse movement

  • Settlement

  • Friction

  • Tightening process

  • Thermal effects

  • Surface coatings

Potential locking solutions can include nylon insert lock nuts, suitable all-metal locking systems, serrated flange nuts or other application-specific locking methods.

The locking mechanism should match the joint requirements.

Nylon Insert Lock Nuts

Nylon insert lock nuts use a polymer insert to create prevailing torque against the mating thread.

JUXIN FASTENERS supplies DIN 985-type nylon insert lock nuts and other applicable configurations according to project requirements.

An important engineering distinction is:

Prevailing torque is not the same as preload.

The nylon insert resists relative thread rotation.

The required joint clamp load still depends on the bolt, tightening process, friction and joint design.

Engineers should also consider:

  • Temperature

  • Chemical exposure

  • Reuse requirements

  • Thread condition

  • Required prevailing torque

All-Metal Locking Systems

Where a polymer locking element is unsuitable, an all-metal locking system may be evaluated according to the application.

Potential considerations include:

  • Temperature

  • Prevailing torque

  • Coating

  • Friction

  • Thread condition

  • Galling risk

  • Reuse requirements

The specific product should be selected from the customer drawing and technical requirement rather than assuming all all-metal lock nuts provide identical performance.

Rail Transit Fasteners: Engineering


Stainless Steel Fasteners in Railway Equipment

Stainless steel fasteners can be considered where corrosion resistance is required.

Depending on the application, materials may include A2 / 304-type or A4 / 316-type stainless steel.

Selection should consider:

  • Environmental exposure

  • Chlorides

  • Chemicals

  • Parent material

  • Temperature

  • Crevice conditions

  • Surface requirements

“Stainless steel” is not a complete corrosion specification.

Stainless Steel Galling

Stainless steel threaded fasteners can experience galling under certain installation conditions.

Risk can be influenced by:

  • Material combination

  • Surface finish

  • Thread condition

  • Assembly speed

  • Lubrication

  • Tightening load

This should be considered when stainless steel nuts, bolts or threaded inserts are used in serviceable railway equipment.

Aluminum Fasteners and Aluminum Rail Vehicle Assemblies

Aluminum can be useful in lightweight rail vehicle assemblies, but aluminum parent material changes the joint behavior.

Engineers should consider:

  • Parent-alloy strength

  • Sheet thickness

  • Local bearing behavior

  • Pull-through

  • Rivet nut pull-out

  • Hole deformation

  • Galvanic compatibility

  • Thermal expansion

An aluminum vehicle panel should not automatically receive an aluminum fastener.

The fastener material should follow the complete mechanical and environmental requirement.

Threaded Inserts for Railway Equipment

Threaded inserts can provide reusable threads where direct threading of the parent material is unsuitable for the required application.

Depending on the component design, threaded inserts can be relevant to:

  • Aluminum components

  • Engineering plastic components

  • Equipment housings

  • Repeated assembly interfaces

  • Maintenance-access components

The term threaded insert covers several different technologies.

Engineers should distinguish between:

  • Rivet nuts for suitable thin sheet

  • Inserts for plastic

  • Other engineered threaded inserts for applicable parent materials

These technologies should not be treated as interchangeable.

Threaded Inserts for Plastic Railway Components

Where engineering plastics are used in equipment housings, electrical components or other suitable rail assemblies, insert selection can depend on:

  • Plastic material

  • Boss geometry

  • Wall thickness

  • Thread size

  • Installation method

  • Pull-out requirement

  • Torque-out requirement

  • Temperature

  • Creep

  • Moisture absorption

JUXIN FASTENERS supplies threaded inserts and plastic/nylon fastening components for drawing-based industrial applications.

Where railway fire or material-performance requirements apply, the relevant material specification must be separately defined and verified.

Self-Clinching Fasteners for Railway Sheet Metal

Self-clinching nuts and studs can provide captive threaded attachment points in suitable sheet metal.

Potential applications can include:

  • Electrical equipment

  • Mounting plates

  • Enclosure assemblies

  • Internal brackets

Suitability depends on:

  • Sheet material

  • Sheet thickness

  • Parent-material hardness

  • Hole preparation

  • Installation force

  • Fastener geometry

A self-clinching nut should not be treated as a direct substitute for a rivet nut without reviewing the manufacturing sequence and parent material.

Cage Nuts for Railway Equipment Racks and Cabinets

Cage nuts can be useful where the enclosure architecture is designed around compatible openings and replaceable threaded hardware.

Potential applications include:

  • Equipment racks

  • Electrical cabinets

  • Control systems

  • Electronic equipment

Potential advantages include:

  • Replaceability

  • Serviceability

  • Installation flexibility

  • Compatibility with suitable rack structures

A cage nut, rivet nut and self-clinching nut all create threaded mounting capability, but they solve different manufacturing problems.

Rail Transit Fasteners: Engineering

Plastic and Nylon Fasteners in Railway Equipment

Plastic and nylon fasteners may be useful in selected rail equipment applications where requirements involve:

  • Electrical isolation

  • Low mass

  • Non-metallic attachment

  • Component positioning

  • Cable management

Potential products include:

  • Plastic screws

  • Nylon screws

  • Plastic nuts

  • Nylon nuts

  • Plastic rivets

  • PCB supports

  • Spacers

  • Standoffs

However, polymer material alone does not establish compliance with electrical, fire, smoke or railway safety requirements.

Where these properties are required, the exact material and applicable project requirements must be defined and verified.

Railway Interior Fastening Solutions

Rail vehicle interiors can contain:

  • Lighting equipment

  • Passenger information systems

  • Equipment panels

  • Covers

  • Seat-related assemblies

  • Handrail-related components

  • Cable-management systems

  • Electronic equipment

Different interfaces can require different fasteners.

For example:

Permanent lightweight panel: blind rivet may be considered.

Removable equipment cover: screw with rivet nut or another reusable thread.

Equipment bracket: bolt-and-nut or captive threaded solution depending on access.

Plastic component: application-specific polymer fastener or insert.

The complete interior system should not be reduced to one “railway fastener.”

Railway Electrical Cabinet Fastening

Railway converter cabinets, control cabinets and electrical enclosures create another distinct fastening environment.

Potential solutions include:

  • Blind rivets

  • Rivet nuts

  • Self-clinching nuts and studs

  • Lock nuts

  • Screws and bolts

  • Plastic and nylon fasteners where appropriate

Important design factors include:

  • Thin-sheet attachment

  • Service access

  • Vibration

  • Corrosion

  • Electrical bonding

  • Temperature

  • Installation sequence

Electrical requirements should be validated separately from mechanical fastening performance.

Protective Bonding and Electrical Interfaces

A metallic fastener does not automatically provide a compliant grounding or bonding path.

Electrical continuity can be affected by:

  • Paint

  • Powder coating

  • Anodizing

  • Oxide layers

  • Contact pressure

  • Contact area

  • Washers

  • Surface preparation

  • Corrosion

Where a fastener forms part of a protective bonding interface, the electrical requirement should be explicitly specified and validated.

Similarly, current-carrying connections such as busbar interfaces require dedicated electrical and thermal engineering beyond ordinary mechanical lock-nut selection.

Galvanic Corrosion in Mixed-Metal Railway Assemblies

Rail equipment can combine:

  • Aluminum

  • Carbon steel

  • Stainless steel

  • Copper alloys

  • Coated metals

When dissimilar metals are electrically connected in the presence of an electrolyte, galvanic corrosion may become a concern.

Risk depends on:

  • Material combination

  • Relative exposed areas

  • Moisture

  • Contaminants

  • Coatings

  • Joint geometry

  • Drainage

  • Service environment

A corrosion-resistant fastener material does not automatically create a corrosion-resistant joint.

The complete material system must be evaluated.

Surface Treatment Is Part of the Fastener Specification

Surface treatment can influence more than appearance.

Depending on the fastener and project, finishes may be selected to address:

  • Corrosion protection

  • Friction

  • Installation behavior

  • Electrical requirements

  • Appearance

Applicable systems may include zinc-based coatings, zinc-nickel systems, stainless steel passivation or other customer-specified finishes where appropriate.

For threaded fasteners, coating can influence friction and therefore the relationship between tightening torque and achieved preload.

This is important when qualifying an alternative supplier.

Railway Vibration: Avoid the “Vibration-Proof Fastener” Shortcut

Railway applications are frequently described as vibration environments.

But vibration does not make one fastener universally correct.

For threaded joints, engineers may need to evaluate:

  • Preload

  • Joint slip

  • Friction

  • Locking mechanism

  • Fatigue

  • Tightening process

For riveted joints:

  • Hole quality

  • Rivet formation

  • Parent-material fatigue

  • Pull-through

  • Joint stiffness

For rivet nuts:

  • Spin-out

  • Pull-out

  • Mating screw behavior

  • Installation quality

The relevant failure mode should be identified before the locking solution is selected.

Thermal Cycling and Mixed Materials

Railway equipment can contain combinations of:

  • Aluminum

  • Steel

  • Stainless steel

  • Copper

  • Engineering plastics

These materials have different thermal-expansion characteristics.

Repeated temperature changes can affect:

  • Joint loading

  • Clamp condition

  • Hole interfaces

  • Panel alignment

  • Polymer creep

  • Electrical contacts

Thermal effects should therefore be considered where operating conditions make them relevant.

Railway Fastener Failure Modes Engineers Should Consider

Instead of asking only for “higher-strength fasteners,” engineers should identify the actual failure mode.

Possible examples include:

Blind Rivets

  • Rivet fracture

  • Parent-sheet pull-through

  • Hole enlargement

  • Poor blind-side formation

  • Fatigue

Rivet Nuts

  • Spin-out

  • Pull-out

  • Thread damage

  • Parent-sheet deformation

  • Incorrect installation

Bolts and Lock Nuts

  • Loss of preload

  • Self-loosening

  • Thread stripping

  • Fatigue

  • Galling

  • Corrosion

Plastic Fasteners and Inserts

  • Creep

  • Pull-out

  • Torque-out

  • Environmental degradation

  • Thermal effects

Different failure modes require different engineering responses.

Railway Fastener Validation Framework

A useful OEM validation process can include:

  1. Classify joint criticality.

  2. Confirm the joint function.

  3. Confirm parent materials.

  4. Confirm material thicknesses.

  5. Confirm hole dimensions.

  6. Confirm fastener geometry.

  7. Confirm material and finish.

  8. Install using production-representative tooling.

  9. Inspect installed condition.

  10. Evaluate parent-material deformation.

  11. Test the relevant mechanical failure modes.

  12. Evaluate vibration or fatigue where required.

  13. Evaluate thermal cycling where required.

  14. Evaluate corrosion and mixed-material compatibility.

  15. Validate electrical performance separately where applicable.

  16. Confirm production repeatability.

The validation depth should increase with the consequence of joint failure.

Railway Standards and Customer Requirements

Railway fasteners can be governed by several layers of technical requirements.

These may include:

  • Customer drawings

  • Fastener dimensional standards

  • Mechanical-property standards

  • Material specifications

  • Coating requirements

  • Railway equipment requirements

  • Vibration requirements

  • Fire and smoke requirements where applicable

  • Electrical requirements

  • Corrosion requirements

Relevant ISO, DIN, EN, BS, ASTM, SAE or other internationally recognized specifications may apply depending on the fastener, equipment and project.

A fastener manufactured to an international dimensional standard is not automatically approved for every railway application.

The governing project specification should always take priority.

What Procurement Should Include in a Railway Fastener RFQ

A high-quality RFQ allows the supplier to evaluate the actual joint rather than quote only a part number.

Provide:

  • 2D drawing

  • 3D model where relevant

  • Application description

  • Joint criticality

  • Fastener type

  • Applicable standard where required

  • Parent material

  • Material grade

  • Sheet thickness

  • Grip range where applicable

  • Hole dimensions

  • Thread size and pitch

  • Fastener material

  • Strength requirement where applicable

  • Surface treatment

  • Mechanical requirements

  • Pull-out requirement

  • Spin-out or torque-out requirement

  • Tightening requirement

  • Vibration or fatigue requirement

  • Temperature

  • Corrosion requirement

  • Electrical requirement where applicable

  • Installation method

  • Applicable railway/customer specifications

  • Annual purchasing volume

  • Sample quantity

  • Packaging requirements

If the project is an alternative-supplier qualification, also explain the current problem.

Examples include:

  • Excessive lead time

  • Rivet pull-through

  • Rivet nut spin-out

  • Thread damage

  • Fastener loosening

  • Galling

  • Corrosion

  • Coating inconsistency

  • Installation difficulty

  • Supply-chain risk

This creates a much stronger supplier-development process than sending only a photograph and quantity.

Standard Fastener or Custom Railway Fastener?

Standard fasteners should normally be evaluated first when they satisfy the engineering requirement.

A custom fastener may become appropriate when the project requires:

  • Non-standard dimensions

  • Special head geometry

  • Restricted installation envelope

  • Specific material

  • Special surface treatment

  • Modified anti-rotation feature

  • Application-specific interface

  • Drawing-controlled tolerances

However, unnecessary customization can increase:

  • Tooling

  • MOQ

  • Qualification work

  • Lead time

  • Supply-chain complexity

The commercial objective should therefore be:

Use a standard fastener where it works; customize where the joint genuinely requires it.

What Supplier Development Should Evaluate Beyond Unit Price

For railway OEM sourcing, the lowest fastener price does not necessarily create the lowest supply risk or installed cost.

Supplier-development teams should also consider:

  • Drawing interpretation

  • Material control

  • Dimensional consistency

  • Surface-treatment control

  • Installation repeatability

  • Sample validation

  • Packaging

  • Traceability requirements

  • Production capacity

  • Lead time

  • Change control

  • Technical communication

For drawing-based parts, the supplier should understand which dimensions and characteristics are functionally critical rather than treating every drawing dimension as an isolated inspection number.

Frequently Asked Questions

What fasteners are used in railway vehicles?

Railway equipment can use blind rivets, rivet nuts, screws, bolts, lock nuts, self-clinching fasteners,

 threaded inserts and polymer fasteners depending on the particular joint. There is no single universal railway fastener.

Which fastener is suitable for thin aluminum rail vehicle panels?

The answer depends on whether the joint is permanent or removable. A blind rivet may be considered for a suitable permanent joint, 

while a rivet nut may be considered where a reusable thread is required. Parent-sheet strength, hole geometry, grip range and corrosion must also be evaluated.

Why are rivet nuts used in railway equipment?

Rivet nuts can create reusable internal threads in suitable thin sheet where direct thread engagement is insufficient or backside access is restricted.

Which lock nut should be used for railway vibration?

Selection depends on the joint preload, movement, temperature, mating surface, serviceability and actual loosening mechanism. “Railway vibration” alone is not enough to select a lock nut.

Are stainless steel fasteners always better for railway applications?

No. Stainless steel can provide useful corrosion resistance, but mechanical requirements, galling, cost, parent material and galvanic corrosion should also be considered.

Can aluminum fasteners be used for lightweight railway assemblies?

Yes, in appropriate applications where their mechanical and environmental performance satisfies the joint requirements. Weight reduction should not replace mechanical validation.

Can a railway fastener be selected only by DIN or ISO standard?

No. A dimensional standard can define the fastener geometry or other characteristics, but project-specific load, material, environment,

 installation and railway requirements must also be considered.

Does JUXIN FASTENERS supply custom railway fasteners?

JUXIN FASTENERS supports drawing-based custom fasteners according to customer dimensions, materials, surface treatments, performance requirements and purchasing volumes.

What should I send when requesting a railway fastener quotation?

Send the 2D drawing, application, parent material, thickness, hole dimensions, mechanical requirements, surface treatment, 

environmental requirements, applicable project specification and annual volume.

From Railway Joint Requirement to OEM Fastener RFQ

The most effective railway fastening specification follows a decision path:

Joint Criticality → Function → Permanent or Serviceable → Access → Parent Material → Thickness → Load → Environment → Fastener Technology → Installation → Validation

This framework helps:

  • Design engineers avoid selecting the wrong fastening technology

  • Procurement teams issue more complete RFQs

  • Supplier-development teams compare technically equivalent alternatives

  • Suppliers understand the actual joint rather than only the fastener dimensions

For rail vehicle interiors, electrical equipment, aluminum panels, equipment modules, cabinets, brackets or other suitable railway assemblies, 

send JUXIN FASTENERS your 2D drawing, application requirements and expected annual purchasing volume.
