ATM Cabinet Anchoring Solutions: M20 Anchor Screws for Secure Equipment Installation


Engineering Guide to ATM Floor Fixing, Concrete Anchoring, M20 Threaded Fasteners and OEM Equipment Mounting Systems

ATM cabinets, banking equipment enclosures and self-service terminals require fastening systems that match their actual installation conditions.

Although an anchor screw or bolt may appear to be a relatively small component, it forms part of the mechanical connection between the equipment and its supporting structure.

For ATM installations, that connection may need to address equipment stability, service access, environmental exposure, structural loading and, where applicable, security-related anchoring requirements.

Selecting an M20 anchor screw is therefore not simply a matter of matching the thread diameter to a mounting hole.

Engineers must evaluate:

  • Equipment weight and center of gravity

  • Cabinet and base plate geometry

  • Anchor type and installation method

  • Supporting material and concrete condition

  • Tension, shear and overturning loads

  • Anchor spacing and edge distance

  • Effective embedment depth

  • Installation torque or other setting requirements

  • Corrosion protection

  • Inspection and installation documentation

  • Applicable equipment and anchoring standards

  • OEM production and procurement requirements

Juxin Fasteners supplies industrial fastening components and supports drawing-based inquiries for M20 threaded fasteners, anchor-related hardware and customized equipment mounting components.

This guide explains how engineering, manufacturing, installation and procurement teams can evaluate fastening solutions for ATM cabinets and related industrial equipment.

ATM Cabinet Anchoring Solutions: M20 Anchor Screws, Concrete Fixings and OEM Installation Hardware

What Is ATM Cabinet Anchoring?

ATM cabinet anchoring is the process of securing an automated teller machine, its cabinet, base or associated equipment structure to an approved supporting surface.

The installation may involve:

  • Cabinet mounting holes

  • Steel base plates

  • Mechanical anchors

  • Concrete screw anchors

  • Threaded anchor rods

  • Nuts and washers

  • Spacers or leveling components

  • Concrete foundations or other engineered supporting structures

The exact configuration depends on the equipment design and site conditions.

ATM Cabinet Fixing vs ATM Safe Anchoring

These terms are related but should not be treated as identical.

ATM Cabinet Fixing

May refer to mechanical attachment of the external equipment cabinet or associated enclosure.

Its engineering requirements depend on the equipment design and intended use.

ATM Safe Anchoring

Refers to anchoring the security-rated safe or cash-protection enclosure within an ATM system.

Where the equipment is subject to a burglary-resistance standard, the anchoring system may form part of the tested security configuration.

Critical Engineering Distinction

A fastener that is mechanically adequate for a general equipment cabinet is not automatically suitable for a security-rated ATM safe.

The complete approved installation system must be followed.

Why ATM Anchoring Requires More Than a Large Bolt

An ATM cabinet can impose several types of load on its mounting system.

These may include:

  • Permanent equipment weight

  • Forces from opening service doors

  • Maintenance-related loading

  • Accidental impacts

  • Environmental actions

  • Overturning effects

  • Site-specific security loading requirements

The actual design loads must be established by the equipment manufacturer or responsible engineer.

A larger bolt diameter does not automatically provide a higher verified anchoring capacity.

The supporting material and anchoring mechanism are equally important.

What Are M20 Anchor Screws?

The term “M20 anchor screw” is used in industrial purchasing for certain large-diameter threaded anchoring components.

However, the terminology can describe different products.

An M20 designation identifies a nominal metric thread diameter of 20 mm.

For a standard ISO metric coarse thread, the usual designation is M20 × 2.5.

This does not specify:

  • Overall fastener length

  • Head design

  • Anchor mechanism

  • Effective embedment depth

  • Drilled hole diameter

  • Installation torque

  • Steel property class

  • Corrosion resistance

  • Approved base material

  • Anchor load resistance

All these characteristics must be determined from the actual product specification.

M20 Anchor Screw vs M20 Anchor Bolt

An anchor bolt may be a cast-in or post-installed fastening component.

A concrete screw anchor develops resistance through engagement with the concrete along a specially designed thread.

A mechanical expansion anchor uses an expansion mechanism to transfer load into the base material.

A threaded rod may form part of an approved bonded anchoring system.

These products are not automatically interchangeable.

Important Product Qualification Rule

A conventional M20 threaded bolt is not automatically a qualified M20 concrete anchor.

If a project requires verified anchoring resistance, the actual anchor system must have suitable technical evidence for the specified application.

ATM Cabinet Anchoring Solutions: M20 Anchor Screws, Concrete Fixings and OEM Installation Hardware

Common Types of Equipment Anchoring Systems

Mechanical Expansion Anchors

Mechanical expansion anchors transfer load into the base material through an expansion mechanism.

Examples include selected wedge and sleeve anchor designs.

Their suitability depends on the specific product and approved conditions.

Concrete Screw Anchors

Concrete screw anchors use specially designed threads that engage with the concrete.

Their installation and performance requirements differ from those of ordinary machine screws.

Bonded Anchors

Bonded anchoring systems use a specified adhesive or resin system together with a compatible anchor rod or reinforcing element.

Performance depends on the complete qualified system, including hole preparation and curing requirements.

Cast-In Anchor Bolts

Cast-in anchors are positioned before concrete placement.

Their design, placement and installation differ from post-installed anchors.

Custom Threaded Mounting Components

Custom bolts, studs, threaded rods, nuts, spacers and other hardware may be used in an engineered mounting assembly.

These components can support the connection, but they should not be represented as independently approved concrete anchors without the necessary evaluation.

Comparison of Anchoring Methods

Anchoring methodGeneral mechanismMain engineering considerations
Mechanical expansion anchorExpansion against the base materialConcrete condition, edge distance, spacing, installation torque
Concrete screw anchorThread engagement with concreteApproved hole preparation, embedment, installation requirements
Bonded anchor systemAdhesive bond and load transferHole cleaning, cure time, temperature, approved components
Cast-in anchor boltEmbedded mechanical anchoragePositioning, concrete design, construction coordination
Custom threaded mounting boltMechanical connection within a designed assemblyThread engagement, strength, mating hardware and mounting geometry

The correct selection depends on the project specification and the anchor manufacturer's technical documentation.

Concrete Anchoring: Why Base Material Matters

Concrete anchoring performance is influenced by the condition and geometry of the base material.

Engineers should consider:

  • Concrete strength

  • Cracked or uncracked concrete

  • Slab thickness

  • Reinforcement location

  • Anchor edge distance

  • Anchor spacing

  • Installation location

  • Expected loading

  • Environmental exposure

Cracked vs Uncracked Concrete

Cracks can change the way an anchor transfers load into the concrete.

An anchor approved only for uncracked concrete should not automatically be used where cracked-concrete performance is required.

For many engineering applications, cracked concrete must be considered unless the design basis justifies otherwise.

Thin Concrete Slabs

A slab may be unsuitable for a particular anchor even when the anchor diameter appears adequate.

Insufficient concrete thickness can increase the risk of:

  • Splitting

  • Concrete breakout

  • Rear-face damage

  • Inadequate embedment

Installation Near Slab Edges

Anchors placed near concrete edges may have reduced resistance or greater installation-related splitting risk.

Engineering Rule

Use the minimum edge distance, spacing and concrete thickness requirements from the actual approved anchor system.

Do not apply generic values based solely on M20 thread diameter.

Understanding Anchor Loads

Tension

Tensile force acts approximately along the anchor axis.

It may arise from overturning or other uplift effects.

Shear

Shear force acts approximately parallel to the supporting surface.

It may arise from lateral loads or equipment movement.

Combined Tension and Shear

ATM mounting systems may experience combinations of these forces.

The design must evaluate the applicable interaction requirements.

Overturning Moment

An overturning moment can increase tension in some anchors while increasing compression elsewhere in the base.

Eccentric Loading

The equipment center of gravity, base geometry and load application points can create unequal anchor forces.

Engineering Insight

A cabinet with four mounting holes does not necessarily distribute all loads equally among four anchors.

Anchor group behavior depends on stiffness, geometry and load direction.

Common Concrete Anchor Failure Modes

Potential failure mechanisms include:

  • Anchor steel failure

  • Concrete cone breakout

  • Anchor pullout

  • Concrete splitting

  • Concrete edge breakout

  • Pryout under shear

  • Failure of the cabinet mounting plate

  • Failure of associated nuts or washers

The governing failure mode is not necessarily the tensile strength of the M20 threaded component.

Concrete Breakout

A portion of the concrete may fracture around an anchor when the applied load exceeds the relevant resistance.

Anchor Pullout

An anchor may lose its engagement with the base material.

Steel Failure

The anchor steel may fracture under excessive loading.

Base Plate Failure

A cabinet mounting plate may bend, tear or deform before the anchor itself fails.

Engineering Information Gain

A fastening system must be evaluated as a load path:

Equipment cabinet → mounting plate → anchor hardware → anchoring mechanism → supporting structure.

If any element is inadequate, increasing the bolt diameter alone may not solve the problem.

ATM Cabinet Anchoring Solutions: M20 Anchor Screws, Concrete Fixings and OEM Installation Hardware

M20 Anchor Thread and Dimensional Specification

A properly prepared OEM drawing should identify more than the nominal M20 thread.

Relevant information may include:

  • Thread designation

  • Thread tolerance

  • Overall length

  • Threaded length

  • Head or drive geometry

  • Shank geometry

  • Washer arrangement

  • Nut specification

  • Material

  • Mechanical properties

  • Surface finish

  • Installation requirements

Metric Thread Example

M20 × 2.5 identifies a nominal 20 mm metric thread with a 2.5 mm pitch.

Other thread pitches may be specified where appropriate.

The correct pitch must be confirmed from the drawing.

Inch Thread Considerations

Some North American equipment uses Unified inch threads.

An M20 thread must not be treated as interchangeable with a nearby UNC or UNF size.

Even when diameters appear similar, thread geometry and pitch differ.

Thread Engagement

The required thread engagement depends on the materials, thread geometry and mechanical requirements.

A steel bolt engaging a lower-strength material may require different design considerations from a steel bolt and compatible steel nut.

Equipment Mounting Plate Design

The cabinet base plate is an essential part of the anchoring system.

Engineers should evaluate:

  • Plate thickness

  • Material grade

  • Hole diameter

  • Hole position

  • Hole spacing

  • Local stiffness

  • Washer bearing area

  • Welded connections

  • Surface coating

  • Installation clearance

Oversized Mounting Holes

Oversized holes may provide installation tolerance, but they can affect bearing behavior and load transfer.

The design must specify suitable washers, plates or other approved details where required.

Thin Cabinet Bases

A thin mounting plate may deform locally around the anchor.

This can affect clamp load and connection stiffness.

Access to Fasteners

ATM cabinets may restrict tool access after equipment installation.

The design should account for:

  • Socket clearance

  • Tool approach

  • Door and service-panel geometry

  • Anchor positioning

  • Installation sequence

Production Engineering Insight

A technically suitable anchor may still create costly installation delays if the cabinet mounting holes are difficult to access or poorly aligned.

Corrosion Protection for ATM Anchoring Hardware

ATM installations may be located indoors, outdoors or in partially sheltered environments.

The corrosion environment should be established before selecting the fastener material and coating.

Carbon Steel Fasteners

Carbon steel components may use appropriate protective coatings.

Possible options include:

  • Zinc plating

  • Zinc-nickel plating

  • Other customer-specified protective systems

Stainless Steel Components

Stainless steel may be suitable for selected environments.

However, stainless steel grades differ in mechanical properties and corrosion behavior.

A stainless steel replacement should not be assumed to provide the same mechanical performance as a specified high-strength carbon steel component.

Outdoor ATM Installations

Outdoor installations may involve:

  • Rainwater

  • Condensation

  • Atmospheric pollution

  • Deicing salts

  • Coastal exposure

  • Temperature changes

Galvanic Corrosion

Contact between dissimilar metals in the presence of an electrolyte may contribute to galvanic corrosion.

The complete mounting assembly should be reviewed.

Coating Selection and Installation

A coating can affect:

  • Thread friction

  • Nut tightening

  • Installation torque

  • Thread fit

  • Corrosion resistance

For qualified anchoring systems, coating and component substitutions must comply with the applicable approval.

Hydrogen Embrittlement Considerations

Certain high-strength steel fasteners may be susceptible to hydrogen embrittlement associated with manufacturing or service conditions.

Material hardness, coating process and application requirements should be evaluated.

International Standards for ATM and Concrete Anchoring

EN 1992-4

EN 1992-4 provides European design rules for fastenings used in concrete.

It addresses relevant concrete anchoring design conditions, including tension, shear and other failure modes.

Its use must be coordinated with the actual anchor's approved technical characteristics.

European Technical Assessment (ETA)

An ETA may provide assessed performance information for a specific anchoring product.

The ETA and associated documentation may identify:

  • Approved base material

  • Anchor dimensions

  • Installation conditions

  • Relevant resistance values

  • Edge distance

  • Spacing

  • Minimum member thickness

  • Intended use conditions

Not every generic M20 threaded component has an ETA.

ACI 318 Chapter 17

ACI 318 Chapter 17 provides provisions for anchoring to concrete in applicable North American structural design contexts.

The governing edition depends on the adopted code and project requirements.

ICC-ES AC193

ICC-ES AC193 provides acceptance criteria for evaluating certain mechanical anchors in concrete.

An evaluation report may be relevant when the project requires evidence of product performance under applicable conditions.

EN 1143-1

EN 1143-1 addresses burglary resistance of specified secure storage units, including ATM safes.

For applicable ATM safe configurations, the anchoring system may be part of the tested security arrangement.

Important Distinction

EN 1143-1 is not a general dimensional standard for M20 screws.

Compliance of a complete ATM safe does not automatically establish certification of every individual fastener.

ISO Metric Thread Standards

Applicable ISO metric thread standards may be relevant to the threaded component's geometry and tolerance.

However, thread conformity alone does not establish concrete anchoring resistance.

Security-Rated ATM Anchoring

Some ATM installations require more than ordinary equipment stability.

For security-rated systems, the installation may need to follow:

  • ATM safe manufacturer's instructions

  • Approved mounting configuration

  • Specified anchoring components

  • Required base construction

  • Security certification conditions

  • Installation documentation

  • Site approval procedures

Why This Matters

A replacement anchor that appears dimensionally similar may not preserve the approved security configuration.

Engineering and Procurement Rule

Do not substitute a different M20 fastener in a security-rated ATM installation without confirming the equipment manufacturer's requirements and any applicable certification conditions.

Installation Documentation

Depending on the project, documentation may include:

  • Approved installation drawing

  • Base construction details

  • Anchor product identification

  • Installation records

  • Inspection results

  • Installer confirmation

  • Site acceptance records

These documents can be important for OEM quality management and installation traceability.

ATM Cabinet Anchoring Solutions: M20 Anchor Screws, Concrete Fixings and OEM Installation Hardware

ATM Anchor Installation Process

The installation procedure must follow the specific approved anchor system.

A typical engineering-controlled workflow includes the following considerations.

Confirm the Supporting Structure

Verify the base material, concrete condition and relevant dimensions.

Check the Approved Drawing

Confirm the anchor positions and mounting-hole geometry.

Verify Anchor Identification

Confirm the correct product, size, material and surface condition.

Prepare the Installation Location

Follow the specified hole preparation and installation procedure.

Install the Anchor

Use the method required for the selected anchoring system.

Apply the Required Setting Procedure

Some anchors require controlled tightening torque.

Others may require a different setting method.

Inspect the Connection

Check the relevant installation and acceptance criteria.

Record the Installation

Maintain the documentation required by the OEM, installer or project specification.

Why There Is No Universal M20 Installation Torque

The required installation torque depends on the actual anchor design.

A torque-controlled expansion anchor may use tightening to activate its expansion mechanism.

A concrete screw anchor may have different installation requirements.

A bonded anchor system has separate curing and setting considerations.

Therefore, specifying one torque value for every M20 anchor would be technically incorrect.

Why Drilled Hole Diameter Cannot Be Assumed from M20

An M20 threaded designation does not determine the drilled hole diameter for every anchoring system.

The hole diameter must be taken from the specific anchor manufacturer's approved instructions.

Why Embedment Depth Matters

Effective embedment depth influences the way load transfers into the supporting material.

The required depth depends on the selected anchor and the design conditions.

A longer fastener does not automatically provide a greater verified load resistance.

Common ATM Anchoring Installation Failures

Incorrect Anchor Type

A fastener is selected without confirming its suitability for the supporting material.

Insufficient Embedment

The anchor does not meet the required installation depth.

Incorrect Hole Preparation

Drilling or cleaning does not comply with the product instructions.

Insufficient Edge Distance

The anchor is positioned too close to the slab edge.

Incorrect Spacing

The anchor group does not meet the applicable design requirements.

Wrong Installation Torque

The installation procedure does not match the anchor product.

Base Plate Deformation

The mounting plate is insufficiently stiff.

Coating Damage

Installation damages the protective finish.

Unapproved Substitution

A different anchor is installed without verifying compatibility or approval.

Missing Installation Records

The installation cannot be adequately traced or verified.

  • Custom studs

  • CNC machined mounting components

  • Spacers and standoffs

  • Nuts and related fastening hardware

  • Customer-specified materials

  • Surface treatments

  • Drawing-based inspection requirements

Specific manufacturing processes and product configurations must be confirmed for each project.

Important Qualification Boundary

Custom manufacturing capability does not automatically mean that a newly designed concrete anchor has been tested, evaluated or approved for structural or security use.

Where anchor qualification is required, the relevant engineering and testing evidence must be established.

Manufacturing Considerations

Depending on the component, manufacturing may involve:

  • Material preparation

  • Forming

  • Machining

  • Thread production

  • Heat treatment where required

  • Surface finishing

  • Inspection

  • Packaging

The actual process depends on the drawing and product requirements.

  • Coating thickness

  • Corrosion-related requirements

  • Surface defects

Documentation

OEM customers may require:

  • Material documentation

  • Dimensional reports

  • Inspection records

  • Lot identification

  • Customer-specific quality records

Actual documentation availability must be agreed upon for the order.

Production Manager Considerations

For repeated ATM cabinet assembly or installation programs, consistency matters.

Production teams should evaluate:

  • Hole-position tolerance

  • Fastener dimensional consistency

  • Packaging by installation set

  • Part identification

  • Installation-tool compatibility

  • Assembly instructions

  • Rework procedures

  • Traceability

Engineering Information Gain: Packaging as an Installation-Control Tool

For multi-site equipment installations, packaging may be designed around a complete approved installation set.

For example, a project-specific kit may contain the required number of identified threaded components, compatible nuts and washers, and installation documentation.

Such a kit must reflect the approved equipment design.

It should not mix unverified components from different anchor systems.

Why This Matters

Consistent packaging and identification can help reduce picking errors, missing components and installation delays.

ATM Cabinet Anchoring Solutions: M20 Anchor Screws, Concrete Fixings and OEM Installation Hardware

Procurement and Supplier Development Considerations

Purchasing teams should evaluate more than the unit price of an M20 component.

Frequently Asked Questions

What is an M20 anchor screw?

The term generally refers to an anchoring-related threaded component with a nominal 20 mm metric thread. 

The exact anchoring mechanism and performance depend on the product design.

Is M20 × 2.5 a standard thread?

M20 × 2.5 is a common ISO metric coarse thread designation. It does not specify the anchor's overall dimensions or load capacity.

Can any M20 bolt be used to anchor an ATM?

No. The component must be suitable for the actual mounting system, supporting structure and applicable engineering requirements.

Does an M20 anchor guarantee ATM security?

No. ATM security depends on the complete equipment, anchoring configuration, installation and applicable security requirements.

What is the difference between an anchor bolt and a concrete screw?

They may use different anchoring mechanisms. A concrete screw relies on specially designed thread engagement with concrete, 

while other anchor bolts may use expansion, bonding or cast-in anchorage.

How deep should an M20 anchor be installed?

The required depth depends on the exact anchor product, supporting material and design conditions. 

There is no universal depth for all M20 anchors.

What installation torque should be used for an M20 anchor?

Use the installation procedure specified for the particular approved anchor. A universal M20 torque value would be inappropriate.

Can M20 anchors be installed in cracked concrete?

Only where the selected anchor system is suitable and approved for the relevant cracked-concrete conditions.

What is EN 1992-4?

It provides European design rules for fastenings used in concrete.

What is EN 1143-1?
