Burnt Blue Grade 5 Titanium 12-Point Flange Nuts

Burnt Blue Grade 5 Titanium 12-Point Flange Nuts

Custom Titanium Fastener Manufacturing for Motorcycle, Motorsport, Performance Cycling and Industrial OEM Applications

JUXIN FASTENERS is an industrial fastener manufacturer specializing in standard and custom-engineered fastening components for international OEM, Tier-1 and Tier-2 manufacturing programs.

Our Grade 5 titanium alloy 12-point flange nuts combine a twelve-point double-hex drive configuration, an integrated flange and a lightweight Ti-6Al-4V alloy body.

The featured product has a distinctive burnt blue and rainbow metallic appearance, making it relevant to manufacturers developing premium motorcycle accessories, racing equipment, performance bicycle components and custom mechanical assemblies.

These titanium flange nuts are also available for engineering evaluation in selected industrial applications where weight reduction, corrosion resistance, compact wrench access or customer-specific geometry are important.

JUXIN FASTENERS supports OEM/ODM manufacturing, made-to-drawing production and industrial batch manufacturing based on customer-supplied 2D engineering drawings, 3D CAD models and technical specifications.

Our broader manufacturing capabilities include cold heading, cold forming, CNC machining and product-specific secondary operations. 

The appropriate process route for a titanium 12-point flange nut depends on material condition, geometry, tolerances, production quantity and manufacturing feasibility.

Product Specifications and Engineering Overview

The listed sizes are based on the existing product information. The exact availability of each size, finish and geometry combination must be confirmed against current production records.

The featured M8 motorcycle nut is an example of this product family rather than a limitation on JUXIN FASTENERS' custom manufacturing capabilities.

What Is a Titanium 12-Point Flange Nut?

A 12-point flange nut has an external twelve-point drive profile and an integrated bearing flange.

The twelve-point drive is also commonly described as a double-hex profile.

It is intended to be engaged with correctly matched twelve-point tooling.

Compared with a conventional six-point drive, the twelve-point arrangement provides more engagement positions around the nut.

This can be useful where tool repositioning is restricted.

The flange provides a bearing surface beneath the nut and may help distribute compressive force across the mating component.

Its effectiveness depends on flange diameter, contact geometry, material properties and joint loading.

12-Point Drive vs. Conventional Hex Drive

The twelve-point configuration does not automatically provide a higher allowable tightening torque.

Permissible installation torque depends on the drive dimensions, titanium material condition, mating bolt, thread engagement, lubrication and joint design.

High-Torque Fastening: What Engineers Must Verify

Some buyers search for high-torque 12-point flange nuts because the drive geometry is associated with specialized mechanical assemblies.

However, high-torque capability must be established through engineering validation rather than inferred from the number of drive points.

Important considerations include:

• Drive profile dimensions and tool engagement.

• Grade 5 titanium material condition.

• Internal thread strength.

• Mating bolt material and strength.

• Thread engagement length.

• Flange bearing pressure.

• Lubrication and friction.

• Tightening procedure.

• Joint preload.

• Fatigue and vibration requirements.

A torque specification developed for a steel nut must not automatically be transferred to a titanium nut.

Why Grade 5 Titanium Alloy?

Grade 5 titanium, also known as Ti-6Al-4V, is a titanium alloy containing approximately 6% aluminum and 4% vanadium.

It is widely recognized for its combination of relatively low density, high strength-to-weight potential and corrosion resistance.

The material is relevant to engineering applications where reducing mass without selecting a low-strength material is important.

Material Density Comparison

For equal solid metal volume, Grade 5 titanium is approximately 44% lighter than carbon steel.

Actual finished fastener mass depends on geometry and the amount of material in the component.

Titanium is denser than aluminum, but its mechanical properties can make it attractive for suitable weight-sensitive designs.

Grade 5 Titanium Material Requirements

Ti-6Al-4V material properties depend on the applicable material specification, product form, heat treatment and manufacturing condition.

For custom titanium flange nuts, engineers should define:

• Material grade and UNS designation.

• Applicable raw material specification.

• Required material condition.

• Mechanical property requirements.

• Chemical composition requirements.

• Dimensional tolerances.

• Surface finish.

• Inspection and documentation requirements.

ASTM B348/B348M is a relevant specification for titanium alloy bars and billets when that product form is selected.

It does not independently establish the finished nut's geometry or mechanical performance.

Burnt Blue and Rainbow Titanium Finishes

The featured titanium nut has a multicolor metallic appearance with blue, gold and purple tones.

In the motorcycle and motorsport accessory markets, this appearance is often described as:

• Burnt Blue Titanium.

• Burnt Titanium Finish.

• Rainbow Titanium.

• Multicolor Titanium Finish.

• Titanium Blue-Purple Finish.

These are useful appearance and commercial search terms.

They do not identify one universally defined coating process.

Polished Titanium

Polishing changes the surface texture and reflectivity.

A polished surface may be specified as a preparation step or as a finished appearance.

Anodized Titanium

Titanium anodizing can produce interference colors associated with oxide-layer thickness.

The resulting appearance depends on the process and surface condition.

PVD-Coated Titanium

Physical Vapor Deposition is a separate coating process.

PVD coatings may be selected for particular decorative or functional requirements, depending on the coating system.

Heat-Colored Titanium

Controlled thermal oxidation may also produce colored titanium surfaces.

The exact appearance and functional consequences depend on processing conditions.

Important Finish Clarification

Polishing, anodizing, PVD and heat coloring are not interchangeable manufacturing descriptions.

The burnt blue appearance shown in the product photograph does not independently confirm which process was used.

JUXIN FASTENERS can review customer-specified finishing requirements according to engineering and production feasibility.

OEM Color Options and Appearance Control

The listed color options include natural titanium, black, gold, blue, red, rainbow and green.

Not every color necessarily uses the same finishing process.

For color-sensitive OEM programs, customers should specify:

• Approved physical color sample.

• Surface preparation.

• Required finishing process.

• Color variation acceptance.

• Coating or oxide requirements.

• Cosmetic inspection criteria.

• Surface handling requirements.

• Packaging protection.

Different colors should not be presented as having different mechanical strength unless supported by product-specific test data.

Metric Thread Sizes and Inch Diameter References

The existing product information identifies M4, M6, M7, M8, M14, M18 and M20.

The following table provides standard metric coarse-thread pitch references and nominal inch diameter conversions.

These pitches are standard coarse-thread references, not verified production drawings for every listed titanium nut.

The final thread pitch, tolerance class, flange dimensions, nut height and drive geometry must follow the approved product specification.

Why M8 Titanium 12-Point Nuts Are Relevant to Motorcycle Buyers

M8 is a common metric nominal thread size used across many mechanical equipment categories.

Motorcycle manufacturers and performance accessory designers may require M8 fasteners with specialized drive geometry, compact dimensions or a titanium appearance.

However, the suitability of an M8 titanium flange nut depends on the specific connection and cannot be determined from nominal thread size alone.

Custom UNC and UNF Thread References for US OEM Customers

American manufacturers may specify Unified National Coarse or Unified National Fine threads for custom titanium flange nuts.

JUXIN FASTENERS can evaluate customer-specific inch-series designs based on technical drawings.

These are standard inch-series thread designations for engineering reference.

They do not imply existing inventory or established production of every size.

Custom UNC and UNF titanium nuts require engineering review of thread geometry, material condition, drive profile, flange design and performance requirements.

Metric and Inch Thread Compatibility

Metric, UNC, UNF, BSW and BSF thread systems are different.

They must not be directly interchanged.

For example, M8 × 1.25 and 5/16-18 UNC are not interchangeable even though their nominal diameters are relatively close.

The mating bolt and nut must use matching thread specifications.

Motorcycle OEM and Performance Motorcycle Accessories

Motorcycle manufacturers and aftermarket equipment producers may evaluate titanium 12-point flange nuts for suitable custom fastening applications.

Potential applications include:

• Approved motorcycle accessory brackets.

• Instrumentation mounts.

• Non-critical fairing accessories.

• Racing electronics brackets.

• Camera and sensor mounts.

• Lightweight equipment covers.

• Custom workshop fixtures.

The burnt blue titanium finish may be particularly relevant to premium motorcycle accessory programs where visible fastener appearance is part of the product design.

Motorcycle Engineering Requirements

Motorcycle fastening systems may experience vibration, thermal cycling, moisture and repeated maintenance.

Engineers should evaluate:

• Required joint preload.

• Installation torque.

• Thread engagement.

• Galling resistance.

• Fatigue loading.

• Mating bolt compatibility.

• Corrosion exposure.

• Service procedures.

Titanium nuts must not automatically replace specified steel nuts in brakes, steering, wheel retention, suspension or other safety-critical motorcycle assemblies.

Superbike, Track Motorcycle and Motorsport Equipment

Track-oriented equipment may place a high priority on mass reduction, tool access and consistent assembly procedures.

Custom Grade 5 titanium 12-point flange nuts may be evaluated for approved accessory or instrumentation assemblies.

Potential applications include:

• Data acquisition equipment.

• Racing electronics accessories.

• Non-critical equipment brackets.

• Instrument mounting systems.

• Specialized maintenance fixtures.

Safety-critical racing applications require project-specific qualification, not merely a material grade declaration.

Motocross and Off-Road Motorcycle Accessories

Off-road motorcycle equipment can experience dirt, impact, vibration, water exposure and frequent disassembly.

For suitable accessory assemblies, titanium may offer useful corrosion resistance and mass reduction.

Engineers must still verify drive accessibility, thread galling, preload, fatigue and maintenance requirements.

Performance Bicycle and Mountain Bike Equipment

Performance bicycle manufacturers may evaluate titanium fasteners for selected lightweight mechanical accessories.

Potential applications include:

• Bicycle computer mounting systems.

• Approved accessory brackets.

• Instrument and sensor mounts.

• Lightweight equipment holders.

• Custom cycling equipment fixtures.

For mountain bike applications, the assembly may experience repeated vibration, moisture and impact.

The twelve-point drive should be selected only where the required tool access and mechanical design justify it.

These titanium nuts must not automatically replace specified fasteners in bicycle brakes, steering, suspension pivots or wheel retention.

Racing Cars and Automotive Motorsport

Motorsport manufacturers may consider custom titanium flange nuts for selected engineered assemblies where weight, packaging space and tool access matter.

Potential applications include:

• Data acquisition hardware.

• Instrumentation brackets.

• Non-critical electronics supports.

• Specialized racing equipment fixtures.

• Approved auxiliary mounting systems.

The use of Grade 5 titanium does not automatically qualify a fastener for high-load racing joints.

Thread strength, fatigue performance, installation procedure and applicable motorsport requirements must be verified.

Automotive OEM and EV Equipment

Automotive and electric vehicle manufacturers may evaluate titanium fasteners for selected custom auxiliary equipment where corrosion resistance, lightweight construction or special geometry is needed.

Potential applications include:

• Approved sensor mounting hardware.

• Non-critical instrumentation brackets.

• Auxiliary equipment fixtures.

• Custom enclosure accessories.

For EV applications, engineers should also evaluate electrical isolation, galvanic compatibility, operating temperature, grounding and fire safety requirements.

Titanium flange nuts are not automatically suitable for high-voltage terminals, current-carrying connections or safety-critical battery retention.

Aerospace Ground Support and Aviation Equipment

Grade 5 titanium is used in aerospace engineering, but material selection alone does not qualify a finished fastener for aircraft installation.

Potential custom industrial applications include:

• Ground support equipment.

• Aircraft maintenance tooling.

• Workshop fixtures.

• Non-flight-critical instrument accessories.

Aircraft-installed hardware requires applicable aerospace fastener specifications, material traceability, dimensional control, testing and formal engineering approval.

JUXIN FASTENERS does not claim that this commercial motorcycle-style titanium nut is an approved aircraft fastener.

Rail Transit and Transportation Equipment

Selected rail equipment may require corrosion-resistant fastening components for auxiliary instrumentation or maintenance equipment.

Potential applications include approved equipment brackets, instrument supports and specialized fixtures.

Rail applications may impose vibration, fatigue, fire, smoke and environmental requirements.

The finished component and assembly must be qualified accordingly.

Marine and Corrosive Industrial Environments

Titanium alloys can offer excellent corrosion resistance in many environments.

Potential applications for custom titanium fastening components include:

• Marine instrumentation.

• Corrosion-exposed equipment accessories.

• Specialized inspection fixtures.

• Selected chemical processing equipment.

• Industrial equipment exposed to aggressive conditions.

However, titanium is not universally corrosion-proof.

The actual environment, chemicals, temperature, crevice conditions and mating materials must be assessed.

Chemical Processing Equipment

Titanium materials are used in chemical processing because of their corrosion performance in suitable media.

Custom titanium nuts may be evaluated for compatible auxiliary equipment and engineered assemblies.

Material selection must consider the specific chemicals, concentrations, operating temperature and galvanic conditions.

Pressure-retaining or safety-critical equipment requires applicable design codes and qualification.

Robotics and Precision Machinery

Robotics and precision equipment manufacturers may require compact custom nuts with specialized drive geometry.

Potential applications include:

• Precision fixtures.

• Instrumentation supports.

• Robotic equipment accessories.

• Custom sensor brackets.

• Lightweight machine components.

Twelve-point geometry can be relevant where tooling access is restricted.

Dimensional accuracy, thread engagement, surface finish and assembly procedures remain critical.

Electrical Cabinets, Power Electronics and Industrial Enclosures

Titanium fasteners may be evaluated for selected specialized enclosure accessories or corrosion-exposed equipment.

Potential applications include:

• Instrument mounting hardware.

• Custom brackets.

• Auxiliary equipment supports.

• Industrial inspection fixtures.

Titanium should not be selected for electrical connections solely because it is corrosion-resistant.

Electrical conductivity, contact resistance, grounding, thermal behavior and material compatibility require separate engineering assessment.

HVAC and Mechanical Equipment

Potential applications include specialized instrumentation brackets, corrosion-exposed auxiliary hardware and custom equipment fixtures.

For ordinary HVAC assemblies, more economical materials may be appropriate.

Titanium should be selected when its material properties provide a justified engineering benefit.

Medical and Laboratory Equipment

Grade 5 titanium may be considered for selected laboratory instruments, equipment fixtures and non-patient-contact mechanical components.

Medical-device applications require separate review of the material specification, surface finish, cleaning compatibility, traceability and regulatory requirements.

The Grade 5 designation alone does not establish implant suitability or medical-device certification.

Construction and Industrial Machinery

Potential applications include specialized equipment fixtures, precision machinery accessories and corrosion-exposed industrial assemblies.

General structural construction connections often require established steel fastener grades and applicable structural specifications.

A titanium 12-point flange nut must not replace such fasteners without formal engineering approval.

Sheet Metal Fabrication and Custom Equipment

The integrated flange may provide a useful bearing surface in suitable fabricated assemblies.

Potential applications include:

• Custom equipment brackets.

• Instrument housings.

• Precision metal enclosures.

• Industrial accessories.

• Specialized machinery covers.

Engineers should verify flange contact area, sheet thickness, bearing pressure, hole diameter and joint preload.

Where access is available from only one side, other fastener types such as blind rivet nuts or self-clinching fasteners may be more suitable.

Titanium Thread Galling and Installation Control

Titanium threaded components may be susceptible to galling, particularly when titanium is assembled against titanium under unfavorable friction conditions.

Galling can cause thread damage, inconsistent tightening or seizure.

Relevant engineering controls may include:

• Appropriate thread surface finish.

• Correct mating thread tolerances.

• Suitable lubrication where permitted.

• Approved surface treatments.

• Controlled assembly speed.

• Validated installation torque.

• Clean threads.

• Defined reuse criteria.

Lubrication changes the torque-to-preload relationship.

Engineers must not apply a dry-thread torque value to a lubricated titanium assembly without reviewing the resulting preload.

Engineering Selection and Failure Prevention

International Standards and Material References

ASTM Grade 5 Titanium / Ti-6Al-4V

Grade 5 titanium is commonly designated Ti-6Al-4V and UNS R56400.

The exact raw material specification and condition must be established through the approved purchasing and engineering documentation.

ASTM B348/B348M

ASTM B348/B348M covers titanium and titanium alloy bars and billets.

It is relevant when the raw material is supplied in a covered product form.

It does not define the finished twelve-point flange nut geometry or automatically certify the finished fastener.

DIN 6923:1983

DIN 6923 is a historical reference associated with hexagon nuts with flange.

It is not a dedicated twelve-point drive nut standard.

A titanium twelve-point flange nut should therefore not be described as fully DIN 6923-compliant without confirming all relevant requirements and the differences in drive geometry.

Custom 12-Point Drive Geometry

For non-standard titanium twelve-point flange nuts, the approved engineering drawing should define:

• Drive profile.

• Tool engagement dimensions.

• Nut height.

• Flange diameter.

• Bearing surface.

• Thread designation.

• Material specification.

• Dimensional tolerances.

• Functional acceptance criteria.

Aerospace and Motorsport Specifications

Application-specific aerospace or motorsport specifications may impose requirements beyond material designation and dimensional geometry.

Compliance must be established through the applicable specification, testing and customer approval.
