Product Specification

High-Strength High-Profile Hex Flange Nuts – Class 10 Steel

Extended-Height Hex Flange Nuts for Automotive OEMs, Industrial Equipment and High-Strength Bolted Assemblies

JUXIN FASTENERS supplies high-strength high-profile hex flange nuts for automotive OEM manufacturers, Tier-1 and Tier-2 suppliers, commercial vehicle producers, 

industrial equipment manufacturers, and international engineering and procurement teams.

High-profile hex flange nuts combine an extended-height hexagonal body with an integrated flange bearing surface.

 Compared with shorter nut configurations of otherwise comparable geometry, the taller body provides greater available wrench engagement height and internal thread length.

The integrated flange increases the bearing contact area compared with a conventional hex nut without a flange. 

In compatible joints, this can eliminate the need for a separate washer and simplify component handling.

The featured product specification includes carbon steel or specified alloy steel, including 40Cr, metric Property Class 10 requirements,

 and RoHS-compliant yellow/iridescent zinc plating with a specified 192-hour neutral salt spray requirement.

JUXIN FASTENERS supports custom OEM flange nut sourcing based on approved engineering drawings, mechanical requirements, 

coating specifications, quality documentation, and production quantities.

Important Product Classification

High-profile flange nuts, standard-profile flange nuts, low-profile flange nuts, and distorted-thread flange locknuts are different product configurations.

The featured product should be classified according to its actual body height, thread geometry, flange design, and mechanical properties.

A taller body does not automatically indicate a locking feature or conformity to a particular dimensional standard.

What Are High-Profile Flange Nuts?

High-profile flange nuts are hexagonal nuts designed with greater body height than a specified standard-profile reference.

The extended body offers additional available tool engagement height and internal thread length.

The flange provides an integrated bearing surface.

These features can be useful where a joint requires:

  • Increased wrench or socket contact height.

  • Additional available internal thread length.

  • An integrated flange bearing surface.

  • High-strength threaded fastening.

  • Controlled assembly and inspection.

  • A customer-specific nut geometry.

The suitability of the design depends on the mating bolt or stud, actual thread engagement, installation access, and joint loading.

High-Profile vs. Standard-Profile Flange Nuts

A standard-profile flange nut has the body height defined by its applicable design or standard.

A high-profile flange nut uses an extended body height.

Potential Advantages of an Extended-Height Design

  • More available wrench engagement height.

  • Additional available internal thread length.

  • Potential suitability for specific extended-engagement joints.

  • Greater flexibility for customer-defined nut dimensions.

Engineering Limitation

A taller nut does not automatically provide higher proof-load capacity.

Mechanical performance depends on the nut property class, effective thread engagement, material, heat treatment, and mating fastener.

The exact height difference must be confirmed dimensionally. A universal percentage increase should not be assumed.

High-Profile Flange Nuts vs. Hexagonal Jam Nuts

These products should not be confused.

A hexagonal jam nut is generally a thin nut used in specified adjustment or locking arrangements.

A high-profile flange nut is an extended-height configuration.

A product cannot be accurately classified as both a thin jam nut and a high-profile nut without explaining a special design.

For OEM procurement, the drawing dimensions take precedence over legacy catalog terminology.

High-Profile Flange Nuts vs. Distorted-Thread Locknuts

A distorted-thread locknut uses an intentionally deformed internal thread region to produce prevailing torque.

A high-profile flange nut is primarily defined by its extended height and integrated flange.

The featured product should not be described as a prevailing-torque locknut unless its thread design includes a verified locking feature.

High-Profile Flange Nuts vs. Serrated Flange Nuts

Flange nuts may use plain or serrated bearing surfaces.

Plain Flange Nuts

Use a non-serrated bearing face to transfer clamping load.

Serrated Flange Nuts

Use serrations intended to engage the mating surface.

The flange underside must be identified from the approved engineering drawing.

A plain flange should not be marketed as a vibration-locking feature.

Extended Wrench Engagement for Automotive Assembly

One potential advantage of a high-profile nut is its increased available wrench engagement height.

In automated or manual assembly, tool engagement affects installation reliability.

Important Engineering Factors

  • Width across flats.

  • Hexagonal body height.

  • Socket depth.

  • Tool clearance.

  • Socket-to-nut fit.

  • Installation orientation.

  • Surface coating.

  • Assembly torque.

Practical Engineering Insight

Increasing nut height can improve available socket contact, but it may also reduce installation clearance.

Production engineers should verify the complete tool envelope before approving an extended-height nut.

Additional Thread Length and Effective Engagement

A taller nut provides more available internal thread length.

However, this does not guarantee that more threads are engaged during installation.

Effective engagement depends on:

  • Mating bolt or stud thread length.

  • Nut internal thread length.

  • Thread pitch.

  • Thread tolerance.

  • Thread runout.

  • Joint stack height.

  • Required bolt protrusion.

Engineering Selection Principle

A longer nut is beneficial only when the mating fastener provides the required usable thread length and the joint geometry supports the design.

The actual thread engagement should be calculated or verified rather than assumed.

Integrated Flange Bearing Surface

The flange distributes clamping load over a wider contact area than the base of a comparable hex nut without a flange.

This can be useful when the joint design requires additional bearing support.

Potential Benefits

  • Wider bearing area.

  • Reduced local bearing pressure under suitable conditions.

  • Integrated washer-like function.

  • Reduced loose-component handling.

  • Simplified assembly inventory.

Important Limitation

An integrated flange is not a universal substitute for every washer.

Some joints require a hardened washer, insulating washer, locking washer, or customer-specific bearing component.

The flange diameter and bearing face must be compatible with the mounting surface.

Oversized and Irregular Mounting Holes

An integrated flange can provide additional bearing coverage around certain oversized or irregularly shaped holes.

However, flange coverage alone does not establish joint suitability.

Engineering Checks

  • Hole diameter and shape.

  • Minimum remaining bearing area.

  • Flange outside diameter.

  • Material thickness.

  • Bearing stress.

  • Joint slip resistance.

  • Bolt position.

  • Clamp-force requirements.

Critical Design Consideration

A flange nut should not be used to compensate for an unacceptable hole condition without engineering approval.

The joint must maintain adequate bearing support and structural integrity.

Metric Property Class 10 High-Strength Steel

The featured product is specified as metric Nut Property Class 10.

This is a mechanical property classification for certain metric nuts.

It is different from Property Class 10.9, which is commonly used for bolts and studs.

Relevant Mechanical Standard

ISO 898-2 specifies mechanical properties for certain carbon steel and alloy steel nuts.

Actual conformity depends on the applicable dimensions, property class, testing requirements, and standard scope.

Mechanical Verification May Include

  • Proof load.

  • Hardness.

  • Thread strength.

  • Material properties.

  • Heat treatment.

  • Dimensional conformity.

  • Mating fastener compatibility.

A nominal Class 10 designation must be supported by the appropriate production and inspection requirements.

Selecting Compatible High-Strength Bolts and Studs

Nut and bolt selection must be based on the complete joint specification.

Important Variables

  • Bolt property class.

  • Nut property class.

  • Thread diameter.

  • Thread pitch.

  • Thread tolerance.

  • Effective engagement.

  • Required preload.

  • Fatigue loading.

  • Operating temperature.

  • Surface treatment.

A high-strength nut should not be selected solely because its nominal strength designation appears similar to that of the bolt.

Carbon Steel and 40Cr Alloy Steel

The featured material information identifies carbon steel and specified alloy steel, including 40Cr.

Material selection must account for:

  • Chemical composition.

  • Heat treatment.

  • Mechanical strength.

  • Hardness.

  • Thread performance.

  • Fatigue requirements.

  • Coating compatibility.

  • Dimensional stability.

The approved material specification determines the final manufacturing requirements.

RoHS-Compliant Yellow/Iridescent Zinc Plating

The featured finish is environmentally compliant yellow or iridescent zinc plating.

For professional OEM procurement, coating specifications should identify the actual process rather than appearance alone.

A coating specification may include:

  • Zinc electrodeposition.

  • Chromium(VI)-free passivation.

  • Coating thickness.

  • Optional sealer.

  • Friction requirements.

  • Corrosion performance.

  • Appearance requirements.

Important Compliance Distinction

A yellow or iridescent appearance does not independently establish RoHS compliance.

The actual coating chemistry and supporting material declarations must meet the applicable requirements.

192-Hour Neutral Salt Spray Requirement

The featured product is specified with 192 hours of neutral salt spray performance.

Neutral salt spray testing is commonly conducted according to ISO 9227 or ASTM B117.

The test report should identify:

  • Test method.

  • Exposure duration.

  • Coating system.

  • Specimen condition.

  • Acceptance criteria.

  • White corrosion evaluation.

  • Red rust evaluation.

  • Test results.

Engineering and Procurement Insight

A statement of “192 hours NSS” is incomplete unless the required corrosion endpoint is defined.

For example, the absence of white corrosion products and the absence of red rust are different acceptance criteria.

The final product specification must match the approved coating test report.

Neutral salt spray results are accelerated laboratory measurements and should not be treated as a direct prediction of field service life.

High-Strength Fasteners and Hydrogen Embrittlement Risk

Electroplated high-strength steel fasteners require careful process control because hydrogen introduced during manufacturing or plating may create an embrittlement risk.

Important Controls May Include

  • Material hardness.

  • Surface preparation.

  • Plating process.

  • Hydrogen embrittlement prevention.

  • Appropriate post-plating treatment.

  • Mechanical testing.

  • Customer-specific specifications.

The applicable process and verification requirements should be defined by the OEM and coating specification.

Coating Friction and Torque–Tension Performance

The coating system affects friction during tightening.

Important Factors

  • Thread friction.

  • Flange bearing friction.

  • Zinc coating.

  • Passivation.

  • Sealer or lubricant.

  • Bolt surface condition.

  • Tightening method.

  • Assembly temperature.

Engineering Requirement

Changing the coating or lubricant may change the relationship between applied torque and achieved clamping force.

Torque values must be validated for the actual joint configuration.

Information Gain: Why Nut Height Alone Is Not Enough

A taller flange nut may appear mechanically superior because it contains more material and provides additional thread length.

However, engineering approval requires more than a height comparison.

1. Thread Engagement Must Be Real

Additional internal thread length has no benefit if the mating bolt does not engage the additional threads.

2. Bearing Area Must Be Adequate

A larger flange must be supported by sufficient mounting material.

3. Tool Access Must Be Verified

A taller nut can improve socket contact while creating interference in restricted spaces.

4. Property Class Must Be Verified

Nut height does not replace mechanical property testing.

5. Coating Must Be Included in Joint Validation

Coating friction and corrosion requirements can affect fastening performance.

6. Locking Performance Is a Separate Requirement

A taller body and integrated flange do not automatically prevent vibration loosening.

These six checks help engineering and procurement teams avoid selecting a fastener based solely on its appearance or catalog name.

DIN 6923 and ISO 4161 Dimensional References

DIN 6923 is a recognized reference for hexagon flange nuts.

ISO 4161 specifies Style 2 hexagon flange nuts within its defined dimensional and thread scope.

Important Standard Qualification

A custom high-profile flange nut may have dimensions outside the relevant standard.

The actual height, flange geometry, thread size, and other dimensions must be compared with the applicable standard before claiming conformity.

Where the product differs, the approved customer drawing should define the required configuration.

ISO 898-2 Mechanical Requirements

ISO 898-2 is a relevant reference for mechanical properties of specified carbon steel and alloy steel metric nuts.

For Property Class 10, the required mechanical performance must be verified according to the applicable standard and customer specification.

Metric Thread Size Range

The original product information identifies the following nominal sizes:

M5Drawing Confirmation Required
M6Drawing Confirmation Required
M8Drawing Confirmation Required
M10Drawing Confirmation Required
M12Drawing Confirmation Required
M14Drawing Confirmation Required
M16Drawing Confirmation Required
M20Drawing Confirmation Required

Important Size Qualification

The original catalog size range does not independently confirm that every size is supplied in Property Class 10 or in the same high-profile geometry.

Availability and conformity must be verified by part number and drawing.

Metric Coarse and Fine Threads

Metric flange nuts may use different thread pitches.

The correct designation must be specified.

For example, M10 alone does not identify every possible fine-thread configuration.

The approved drawing must define the required pitch and tolerance.

American Inch-Series Thread References

American OEMs may specify Unified inch-series threads such as:

  • 1/4"-20 UNC

  • 5/16"-18 UNC

  • 3/8"-16 UNC

  • 1/2"-13 UNC

  • 1/2"-20 UNF

  • 5/8"-11 UNC

  • 5/8"-18 UNF

These are market reference designations, not confirmation of availability for this specific product.
