Important Specification Distinction

The original catalog lists several mechanical property classes.

The high-strength designation applies specifically to verified high-strength configurations, particularly Property Class 10 for the featured metric product.

Other property classes must be identified accurately and should not automatically be marketed as Class 10.

What Are High-Strength Steel Flange Nuts?

High-strength steel flange nuts are internally threaded hexagon nuts with an enlarged circular flange at one end.

The flange creates an integral bearing surface.

When the nut is tightened against a compatible joint surface, the flange distributes the contact force over a larger area than the bearing face of a standard hex nut.

This can be useful for mechanical assemblies requiring:

  • Wider bearing contact.

  • Simplified washer management.

  • High-strength threaded fastening.

  • Consistent component geometry.

  • Corrosion-resistant coating options.

  • Efficient production assembly.

The complete joint must still be designed to achieve the required clamp force and mechanical reliability.

How the Integral Flange Works

The flange is formed as part of the nut body.

Unlike a separate washer, the flange remains integrated with the nut.

Potential Engineering Benefits

  • Wider bearing surface.

  • Fewer loose assembly components.

  • Simplified material handling.

  • Potential reduction in washer installation steps.

  • Convenient hexagon wrenching geometry.

  • Compatibility with selected automated assembly systems.

Important Engineering Limitation

A flange nut does not automatically replace every washer.

Hardened washers, sealing washers, spring washers and specialized bearing components may serve different functions.

The flange diameter, bearing surface, joint material and applied load must be evaluated.

Plain Flange vs. Serrated Flange Nuts

Flange nuts are available with different bearing surfaces.

Plain Flange Nuts

Have a relatively smooth bearing surface without locking serrations.

They distribute bearing pressure across the flange contact area.

Serrated Flange Nuts

Have teeth or serrations on the flange face.

The serrations may engage the mating material and provide some resistance to rotation.

However, serrations can damage protective coatings or mark the mating surface.

Featured Product

The product photograph indicates a plain, non-serrated flange.

Therefore, this product should not be described as a serrated flange locknut unless a separate serrated version is confirmed.

Plain Flange Nuts vs. Prevailing-Torque Locknuts

A standard plain flange nut does not contain a built-in prevailing-torque locking feature.

It should not automatically be described as a self-locking nut.

For applications requiring resistance to loosening under vibration, engineers must evaluate the complete joint.

Potential alternatives include:

  • Approved prevailing-torque nuts.

  • Distorted-thread flange locknuts.

  • Nylon-insert flange locknuts.

  • Serrated flange nuts, where appropriate.

  • Other validated locking methods.

These designs have different functional characteristics and are not automatically interchangeable.

Property Class 10 High-Strength Steel Flange Nuts

Property Class 10 is an important designation for higher-strength metric steel nuts.

The applicable mechanical property requirements are addressed by ISO 898-2.

A Class 10 nut must satisfy the specified mechanical requirements for its product configuration.

Engineering Considerations

  • Nut proof load.

  • Mating bolt property class.

  • Thread engagement.

  • Joint preload.

  • Nut height.

  • Flange geometry.

  • Coating friction.

  • Operating temperature.

  • Fatigue loading.

  • Installation procedure.

Class 10 Nut and Class 10.9 Bolt Compatibility

Class 10 nuts may be used in appropriately designed fastening systems involving suitable Class 10.9 bolts.

However, compatibility must be verified against the applicable standards and joint design.

A Class 10 nut designation does not guarantee the performance of the complete bolted joint.

Metric Class 10 vs. SAE Grade 8

American buyers may search for high-strength flange nuts using SAE Grade 8 or Grade G terminology.

These are not the same designation systems as ISO Property Class 10.

The standards differ in their classification methods and technical requirements.

Metric and inch-series products must be specified separately.

DIN 6923 Hexagon Flange Nut Standard

DIN 6923 is a recognized German product standard for hexagon nuts with flange.

It is an important reference for metric flange nut sourcing.

The applicable standard edition and actual product geometry must be verified.

Key Dimensional Characteristics

  • Thread diameter.

  • Thread pitch.

  • Nut height.

  • Width across flats.

  • Width across corners.

  • Flange diameter.

  • Flange thickness.

  • Bearing face geometry.

  • Thread tolerance.

  • Dimensional tolerances.

DIN 6923 and Related International Standards

ISO 4161 is a related international standard for hexagon nuts with flange.

However, dimensional details and applicable product requirements must be checked against the selected standard edition.

DIN 6923 and ISO 4161 should not automatically be described as fully interchangeable for every product.

Metric Thread Sizes

The original product range includes:

  • M4

  • M5

  • M6

  • M8

  • M10

  • M12

  • M14

  • M16

  • M20

Common metric coarse-thread references include:

  • M4 × 0.7

  • 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 nominal engineering references.

The actual thread pitch and availability of Class 10 coated variants must be confirmed.

Metric Fine-Pitch Flange Nuts

Some industrial applications require metric fine-pitch threads.

Potential selection factors include:

  • Thread engagement.

  • Nut dimensions.

  • Mating bolt compatibility.

  • Joint preload.

  • Installation torque.

  • Manufacturing feasibility.

Fine-pitch requirements should be reviewed separately against the approved drawing.

Inch-Series Flange Nuts

The original product information indicates that inch-series options may also be available.

American procurement searches may include:

  • SAE Grade 8 Flange Nuts

  • Grade G Flange Nuts

  • UNC Flange Nuts

  • UNF Flange Nuts

  • High-Strength Inch-Series Flange Nuts

These should be treated as separate product configurations.

Important Thread Compatibility Note

Metric and UNC/UNF threads are not directly interchangeable.

Examples:

  • M6 × 1.0 is not interchangeable with 1/4"-20 UNC.

  • M8 × 1.25 is not interchangeable with 5/16"-18 UNC.

  • M10 × 1.5 is not interchangeable with 3/8"-16 UNC.

Do not substitute an inch-series nut for a metric nut based only on similar nominal dimensions.

Dacromet Zinc-Flake Coating

The featured product uses a Dacromet-type zinc-flake coating.

Dacromet is associated with a family of inorganic zinc-rich protective coating technologies.

In industrial procurement, the term is frequently used when discussing zinc-flake corrosion protection.

However, Dacromet is a specific commercial coating designation.

Other zinc-flake systems may use different formulations, topcoats and proprietary technologies.

Engineering Description

The broader technical term is Non-Electrolytically Applied Zinc-Flake Coating.

This is especially useful for international OEM sourcing because it describes the coating technology rather than relying solely on a trade name.

ISO 10683 Zinc-Flake Coating Systems

ISO 10683:2018 specifies requirements for non-electrolytically applied zinc-flake coating systems on steel fasteners.

The standard covers specified systems with or without:

  • Hexavalent chromium.

  • Topcoats.

  • Integrated lubricants.

  • Additional lubrication.

The coating requirements must be selected according to the customer's technical specification.

Corrosion Protection

Zinc-flake coatings are used to provide corrosion protection to steel fasteners.

Actual performance depends on:

  • Coating formulation.

  • Coating thickness.

  • Basecoat and topcoat.

  • Surface preparation.

  • Application process.

  • Curing.

  • Environmental exposure.

  • Handling damage.

A specific salt spray resistance rating must not be assumed without supporting test evidence.

Hydrogen Embrittlement Considerations

High-strength steel fasteners may be susceptible to hydrogen embrittlement under certain manufacturing and service conditions.

Non-electrolytic zinc-flake coating processes are often considered for high-strength fasteners because they can reduce the risk of introducing hydrogen compared with certain electrolytic coating processes.

However, the risk depends on the complete manufacturing process.

Relevant Engineering Controls

  • Material strength.

  • Heat treatment.

  • Surface preparation.

  • Coating process.

  • Manufacturing quality controls.

  • Operating stress.

  • Customer-specific testing.

Zinc-flake coating does not automatically eliminate every hydrogen embrittlement risk.

RoHS Compliance and Dacromet Coatings

RoHS compliance must be evaluated against the actual coating chemistry.

Some zinc-flake coating systems are formulated without hexavalent chromium.

Other systems may contain hexavalent chromium.

Therefore, a coating should not automatically be described as RoHS-compliant simply because it is zinc-flake coated or meets ISO 10683.

Where RoHS compliance is required, specify an approved Cr(VI)-free coating system and obtain appropriate supporting documentation.

Coating Friction and Torque–Tension Performance

Coating systems influence friction between mating threads and bearing surfaces.

For high-strength flange nuts, friction affects the relationship between applied tightening torque and achieved bolt preload.

Critical Variables

  • Thread friction.

  • Flange bearing friction.

  • Coating formulation.

  • Topcoat.

  • Lubrication.

  • Mating bolt coating.

  • Surface condition.

  • Installation tooling.

A tightening torque developed for an uncoated nut should not automatically be used for a zinc-flake-coated nut.

The OEM must establish the approved torque–tension relationship.

Coating Thickness and Thread Fit

Coating thickness can affect thread fit and assembly performance.

For OEM sourcing, the coating specification should address:

  • Coating thickness.

  • Thread allowance.

  • Thread engagement.

  • Installation friction.

  • Corrosion performance.

  • Surface appearance.

  • Inspection methods.

The finished nut must remain compatible with the specified mating bolt.

Other Surface Treatment Options

The original product family also lists:

  • Iridescent Zinc Plating.

  • Clear Zinc Plating.

  • Blue-Passivated Zinc Plating.

  • Zinc-Nickel Alloy Plating.

  • Black Zinc Plating.

  • Yellow Zinc Plating.

  • Zinc-Flake Coating.

These finishes may be considered for customer-specific applications.

Each coating has different corrosion, friction and process characteristics.

Availability must be confirmed for the selected mechanical property class.

Flange Nuts for Oversized or Irregular Holes

The wider flange may provide additional bearing coverage around a clearance hole.

However, the flange must be large enough to maintain the required contact area.

Engineering Factors

  • Hole diameter.

  • Hole shape.

  • Flange outside diameter.

  • Bearing surface area.

  • Joint material strength.

  • Applied clamp force.

  • Edge distance.

  • Hole position tolerance.

A flange nut is not automatically suitable for every oversized or irregularly shaped hole.

Excessive hole size or insufficient bearing support may require a different joint design.
