DIN 6927 All-Metal Distorted-Thread Flange Lock Nuts

DIN 6927 All-Metal Distorted-Thread Flange Lock Nuts for Vibration-Resistant OEM Assemblies

JUXIN FASTENERS supplies carbon steel all-metal distorted-thread flange lock nuts for automotive components, industrial machinery, heavy equipment and other OEM fastening applications.

These specialized self-locking hex flange nuts use a controlled metallic thread deformation to generate prevailing torque during installation and removal.

Unlike nylon-insert lock nuts, the locking function does not depend on a polymer insert.

The integrated flange provides an enlarged bearing surface that can distribute the applied clamping load over a wider contact area than a comparable non-flanged hex nut.

Common American industrial terms include Distorted-Thread Flange Nuts, All-Metal Prevailing Torque Flange Nuts, Deformed-Thread Flange Locknuts and Metal Locking Flange Nuts.

The relevant international standard families include DIN 6927, DIN EN 1664 and ISO 7044, subject to the specific dimensional and technical requirements of each standard edition.

JUXIN FASTENERS supports bulk production inquiries, standard-based sourcing and custom engineering requirements for OEM manufacturers, 

Tier-1 and Tier-2 suppliers, mechanical design engineers, production managers and global procurement teams.

What Are Distorted-Thread Flange Lock Nuts?

Distorted-thread flange lock nuts are all-metal self-locking fasteners designed to resist unintended rotation through a prevailing-torque locking feature.

A controlled deformation in the nut thread or body creates interference with the mating bolt thread.

This interference generates resistance to rotation even before the nut reaches the joint seating surface.

The resulting resistance is called prevailing torque.

A properly specified prevailing-torque nut can provide additional resistance to loosening under certain vibration and dynamic loading conditions.

However, prevailing torque is not a substitute for adequate bolt preload, suitable joint design or correct installation.

How the All-Metal Locking Mechanism Works

A conventional free-spinning hex nut can generally be turned along a compatible bolt before it contacts the joint surface.

An all-metal prevailing-torque nut behaves differently.

Its locking feature produces additional rotational resistance as the nut engages the mating thread.

The prevailing-torque feature may be created through controlled deformation of the nut thread or body.

The exact deformation geometry depends on the product design.

Prevailing-On Torque

Prevailing-on torque is the torque required to rotate the nut onto the mating thread before clamp force develops.

Prevailing-Off Torque

Prevailing-off torque is the torque required to rotate the nut during removal after clamp force has been relieved.

Clamp Force

Clamp force is the compressive force generated in the joint through bolt tension.

Important Engineering Distinction

Prevailing torque and tightening torque are not identical.

A specified assembly torque may include the effects of thread friction, bearing friction and the prevailing-torque locking feature.

For critical joints, installation procedures should be developed using the applicable joint engineering requirements and validation data.

DIN 6927, DIN EN 1664 and ISO 7044: Understanding the Standards

DIN 6927

DIN 6927 is a historical German standard designation associated with prevailing-torque all-metal hexagon flange nuts.

It remains widely recognized in industrial purchasing documents and older engineering drawings.

DIN EN 1664

DIN EN 1664 covers prevailing-torque all-metal hexagon nuts with flange.

It replaced the earlier DIN 6927 designation in the German standard system.

ISO 7044

ISO 7044:2012 specifies prevailing-torque all-metal hexagon nuts with flange, style 2, in the M5–M20 range.

The standard includes defined product grades and property classes.

Are These Standards Automatically Interchangeable?

No.

Although the standards address related fastener designs, differences may exist between standard editions in dimensions, geometry and other technical details.

The correct standard and edition should be specified in the purchase order or engineering drawing.

For replacement projects, the buyer should verify:

• Nut height.

• Width across flats.

• Flange dimensions.

• Thread specification.

• Property class.

• Locking performance.

• Surface treatment.

• Assembly clearance.

Do not substitute one standard designation for another without technical review.

ISO 2320: Prevailing-Torque Functional Performance

ISO 2320 specifies functional requirements and test methods for prevailing-torque steel nuts.

Relevant characteristics include:

• Prevailing-on torque.

• Prevailing-off torque.

• Torque and clamp-force behavior.

• Proof-load-related requirements.

• Defined installation and removal test conditions.

ISO 2320 provides a technical basis for evaluating locking performance.

The actual acceptance requirements depend on the nut specification and customer agreement.

All-Metal Distorted-Thread Nuts vs. Nylon-Insert Lock Nuts

Both designs are intended to provide resistance to unintended loosening.

However, their locking mechanisms differ.

All-Metal Distorted-Thread Flange Nuts

• Use a metallic prevailing-torque feature.

• Do not rely on a nylon insert.

• Can be evaluated for applications involving elevated temperatures.

• Require appropriate installation torque control.

• May experience a reduction in prevailing torque after repeated use.

Nylon-Insert Flange Lock Nuts

• Use a non-metallic insert to create thread interference.

• Have temperature limitations associated with the insert material.

• May provide different installation and reuse characteristics.

• Require compatibility with the operating environment.

The correct choice depends on the actual joint design, temperature, vibration, serviceability and customer requirements.

Neither design should be described as universally superior.

Temperature Considerations

All-metal prevailing-torque nuts are commonly considered for applications where polymer inserts may be unsuitable.

ISO 2320 identifies a general application temperature range for conforming all-metal prevailing-torque nuts.

However, the actual allowable operating temperature of a finished fastener assembly also depends on:

• Steel grade.

• Heat treatment.

• Surface coating.

• Lubrication.

• Mating bolt properties.

• Joint design.

• Required prevailing-torque retention.

A specific elevated-temperature rating must be validated for the actual product and assembly.

Integrated Flange Engineering

The flange is an important functional feature.

Compared with a conventional non-flanged hex nut, the flange provides a larger contact area against the mating surface.

Potential advantages include:

• Wider bearing contact.

• Reduced need for a separate plain washer in suitable designs.

• Improved load distribution.

• Compatibility with selected production assembly processes.

• Reduced number of loose assembly components.

Important Limitation

A flange does not automatically make an oversized or damaged mounting hole acceptable.

The flange must provide sufficient bearing area on properly designed and inspected mating surfaces.

Hole size, edge distance, material strength and joint geometry remain important.

Plain Flange vs. Serrated Flange

Some flange nuts have smooth bearing surfaces.

Others incorporate serrations or specialized anti-rotation features.

The featured product should not be assumed to have a serrated flange unless confirmed by the drawing.

Serrated and non-serrated flange designs can affect bearing surfaces, coatings and joint behavior differently.

Carbon Steel Material and Property Classes

The original product range identifies carbon steel in property classes 8 and 10.

Nut property classes must be evaluated according to the applicable mechanical property standard.

Property Class 8

Property Class 8 nuts are used in many industrial bolted joint applications.

Suitability depends on the mating bolt, proof-load requirements and assembly design.

Property Class 10

Property Class 10 nuts are intended for applications requiring the mechanical performance associated with that property class.

They may be selected for certain higher-strength bolted joints.

Bolt and Nut Compatibility

A nut must be compatible with the specified mating bolt property class and the required joint loading.

For example, an ISO property class 10 nut may be relevant to a joint using a suitable property class 10.9 bolt.

However, bolt compatibility should be established through the applicable standards and engineering design.

A property class designation alone does not establish the required installation torque.

Available Metric Thread Sizes

The original product information lists:

• M5

• M6

• M8

• M10

• M12

• M14

• M16

• M20

Common ISO metric coarse thread pitches for reference include:

• M5 × 0.8

• M6 × 1.0

• M8 × 1.25

• M10 × 1.5

• M12 × 1.75

• M14 × 2.0

• M16 × 2.0

• M20 × 2.5

These are common nominal coarse-thread designations.

The actual thread pitch and tolerance class must be confirmed for each ordered product.

Metric and Inch Thread Reference

Some overseas buyers search for flange lock nuts using UNC or UNF terminology.

However, the featured product range is identified using metric thread sizes.

Metric and Unified inch-series threads are not directly interchangeable.

Any request for a corresponding UNC or UNF distorted-thread flange nut should be evaluated as a separate specification.

Availability of inch-series products must be confirmed rather than inferred from metric dimensions.

Surface Treatment and Corrosion Protection

Surface treatment affects corrosion resistance, appearance, friction and assembly behavior.

The original product information identifies several coating options.

Clear Zinc Plating

Clear zinc plating is used for corrosion protection in suitable industrial environments.

Actual performance depends on plating thickness, passivation and environmental exposure.

Blue-Passivated Zinc Plating

Blue-passivated zinc finishes may be specified where the appearance and corrosion requirements are appropriate.

Yellow Zinc Plating

Yellow zinc finishes may be used according to customer requirements.

Modern environmental compliance requirements must be considered when selecting passivation chemistry.

Black Zinc Plating

Black zinc finishes may provide a dark appearance together with a specified corrosion protection system.

Zinc-Nickel Alloy Plating

Zinc-nickel alloy coatings may be selected for more demanding corrosion requirements.

The actual coating thickness, passivation and corrosion performance must be specified.

Zinc-Flake Coating

Zinc-flake systems are used for corrosion protection on industrial fasteners.

Coating performance depends on the approved coating system and application process.

Dacromet-Type Coating

Dacromet is a historical trade name associated with certain zinc-flake coating technologies.

Current coating chemistry, environmental compliance and availability must be confirmed.

A generic zinc-flake coating should not automatically be described as a specific branded Dacromet product.

Coating Standards

Depending on the selected system, relevant standards may include:

• ISO 4042 for electroplated coating systems.

• ISO 10683 for non-electrolytically applied zinc-flake coating systems.

Coating specifications should identify the applicable standard, thickness, corrosion performance and any required post-treatment.

Hydrogen Embrittlement Considerations

Electroplating certain high-strength steel fasteners may introduce hydrogen embrittlement concerns.

The risk depends on material strength, manufacturing process, coating method and applicable requirements.

The selected coating process should be reviewed against the mechanical property class and customer specifications.

Coating Effects on Prevailing Torque

The locking performance of a distorted-thread flange nut can be affected by surface treatment.

Important factors include:

• Coating thickness.

• Thread fit.

• Friction coefficient.

• Lubrication.

• Prevailing-on torque.

• Prevailing-off torque.

• Repeated installation.

• Mating bolt surface treatment.

A coating change should not be assumed to leave the prevailing-torque characteristics unchanged.

For OEM applications, the coated fastener should be evaluated according to the required functional performance.

Installation Torque and Assembly Engineering

All-metal prevailing-torque nuts require attention to the difference between thread locking resistance and joint clamping.

The installation procedure should consider:

• Nut property class.

• Mating bolt property class.

• Thread condition.

• Surface treatment.

• Prevailing-on torque.

• Bearing friction.

• Thread friction.

• Required clamp force.

• Joint geometry.

• Assembly tool calibration.

Why Conventional Torque Tables May Not Be Sufficient

Generic torque tables may not account for the prevailing-torque locking feature or the actual coating friction.

For critical OEM joints, the tightening specification should be developed and validated for the specific nut, bolt, coating and assembly.

Automated Assembly Considerations

Production managers should evaluate:

• Nut feeding.

• Thread engagement.

• Run-down torque.

• Prevailing-torque monitoring.

• Final tightening.

• Tool capacity.

• Cross-threading prevention.

• Process repeatability.

• Inspection and traceability.

The selected fastening system must be compatible with the assembly equipment.

Can Distorted-Thread Flange Nuts Be Reused?

Prevailing-torque performance may decrease after repeated installation and removal.

Reuse should be based on:

• Applicable standard requirements.

• Customer specifications.

• Prevailing-off torque measurements.

• Thread condition.

• Coating condition.

• Joint criticality.

• Maintenance procedures.

A nut should not be reused solely because it can still be threaded onto the bolt.

Likewise, it is inaccurate to describe every all-metal prevailing-torque nut as strictly single-use without considering the relevant specification.

Common Engineering Problems and Corrective Measures

1. Excessive Installation Torque

Possible causes include excessive thread deformation, unsuitable coating friction or incompatible mating threads.

Review prevailing-on torque and thread compatibility.
