Wine Red Anodized 6061 Aluminum Nylon-Insert Hex Flange Lock Nuts

Wine Red Anodized 6061 Aluminum Nylon-Insert Hex Flange Lock Nuts – M2–M8

JUXIN FASTENERS supplies wine red anodized 6061 aluminum nylon-insert hex flange lock nuts for industrial OEM manufacturers, 

bicycle component producers, mountain bike equipment builders, motorsport suppliers, robotics manufacturers and precision engineering applications.

These lightweight fasteners combine a 6061 aluminum alloy body, a non-metallic nylon locking insert and an integrated hexagonal flange. T

he nylon insert produces prevailing torque to resist rotational loosening, while the flange provides a wider bearing surface for appropriately designed mechanical joints.

The wine red anodized finish offers a distinctive burgundy-red appearance for manufacturers requiring lightweight fastening components with coordinated colors, 

corrosion protection and consistent product presentation.

Common North American and European product names include wine red aluminum nylon-insert flange lock nuts, 

burgundy aluminum nyloc flange nuts, 6061 aluminum prevailing-torque locknuts, lightweight aluminum hex flange nuts and DIN 6926-style aluminum locking nuts.

Product Specifications

Engineering and Standards Clarification

This product is manufactured from 6061 aluminum alloy and uses a nylon insert to create prevailing torque.

DIN 6926 and ISO 7043 primarily address steel prevailing-torque hex flange nuts. ISO 7043:2012 specifies sizes M5 through M20 and steel property classes 8, 9 and 10.

The aluminum M2, M2.5, M3 and M4 configurations fall outside the ISO 7043 size range.

Even for M5, M6 and M8, aluminum material properties and locking performance must be specified separately.

These products should therefore be described as DIN 6926-style aluminum nylon-insert flange lock nuts unless compliance with a particular specification has been independently established.

Why Choose 6061 Aluminum Alloy?

6061 is a heat-treatable aluminum alloy containing magnesium and silicon as its principal alloying elements.

It is widely used in lightweight mechanical components, transportation equipment, precision-machined parts and industrial assemblies.

Lightweight Construction

6061 aluminum has a typical density of approximately 2.70 g/cm³, compared with approximately 7.85 g/cm³ for carbon steel.

For equivalent solid metal volumes, aluminum is approximately 65% lighter than steel.

Actual finished nut weight depends on the flange geometry, overall height, thread dimensions and nylon insert.

For bicycle accessories, motorsport equipment, drones and robotics, reducing unnecessary component mass can support lightweight product design.

Mechanical Properties

The mechanical properties of 6061 aluminum depend on its temper and manufacturing condition.

The material designation 6061 alone does not confirm a specific tensile strength, proof-load capability or thread stripping resistance.

For production programs requiring defined mechanical performance, the customer should specify the required material temper and acceptance criteria.

Aluminum lock nuts must not automatically replace Class 8 or Class 10 steel lock nuts in load-bearing applications.

Corrosion Resistance

6061 aluminum provides good atmospheric corrosion resistance in suitable environments.

Anodizing creates an additional oxide surface layer that can improve surface protection and appearance.

However, anodized aluminum is not immune to galvanic corrosion, chemical attack or coating damage.

Machinability and Custom Geometry

6061 aluminum can be machined into precision components with controlled thread and flange dimensions.

For custom OEM designs, engineering review should address material condition, thread tolerances, flange geometry, insert retention and surface treatment.

Wine Red Anodizing: Color, Protection and Product Identification

Wine red anodizing gives the aluminum body a deep red or burgundy appearance.

This finish is particularly relevant to premium bicycle accessories, mountain bike components, motorsport equipment, RC racing hardware and specialized mechanical products.

Benefits of Wine Red Anodizing

• Distinctive appearance for premium product designs.

• Color coordination with bicycle and motorsport accessories.

• Potential component identification during assembly.

• Protective anodized oxide layer.

• Lightweight aluminum construction.

• Custom appearance requirements for OEM production.

Wine Red vs. Bright Red vs. Purple

Wine red is a darker red shade that may have burgundy or maroon characteristics.

Bright red typically has a more vivid appearance, while purple has a different color balance.

Because anodized colors depend on alloy condition, dye chemistry, oxide thickness and sealing, customers should not rely solely on a digital color name.

For OEM production, an approved physical sample is recommended.

Anodizing Process and PVD Clarification

Anodizing and physical vapor deposition (PVD) are different surface treatment processes.

This product is described as wine red anodized aluminum.

PVD should only be specified when supported by the actual production process and coating documentation.

OEM Color Matching and Production Consistency

For industrial bulk orders, wine red anodizing requirements may include:

• Approved physical color sample.

• Anodizing type and coating thickness.

• Surface preparation requirements.

• Color uniformity criteria.

• Surface sealing requirements.

• Cosmetic defect limits.

• Batch-to-batch appearance consistency.

• Outdoor weathering requirements where applicable.

• Packaging protection against scratches.

Color appearance may vary with material temper, machining condition, anodizing process and lighting.

Outdoor Corrosion and Color Stability

Bicycles and motorsport equipment may be exposed to sunlight, rain, road salt, mud, cleaning agents and repeated handling.

Outdoor durability depends on the anodizing process, sealing quality, exposure conditions and coating damage.

Where long-term color retention is important, engineers should define appropriate testing and acceptance requirements.

Metric Thread Sizes M2–M8

The following table provides standard metric coarse-thread pitch references.

These values are thread pitch references only.

Actual flange diameter, nut height, width across flats, thread tolerance and nylon insert geometry must follow the approved product drawing.

M2 and M2.5 Miniature Locknuts

M2 and M2.5 versions may be considered for compact instruments, RC models, miniature robotics and precision mechanical accessories.

Small aluminum threads require careful installation torque control.

M3 and M4 Locknuts

M3 and M4 versions are relevant to drone accessories, RC racing equipment, compact robotics, electronic enclosures and lightweight brackets.

Engineers should verify prevailing torque, thread engagement and joint preload.

M5, M6 and M8 Locknuts

M5, M6 and M8 versions may be considered for bicycle accessories, motorsport equipment mounts, lightweight machinery covers and suitably engineered mechanical assemblies.

Thread diameter alone does not establish suitability for structural or safety-critical joints.

UNC and UNF Inch-Series Thread References

North American OEM manufacturers may request Unified National Coarse (UNC) or Unified National Fine (UNF) threads for custom aluminum lock nuts.

The following table provides common inch-series thread designations for engineering reference.

These are thread references for custom engineering inquiries, not confirmation of available stock or standardized aluminum flange locknut configurations.

ASME B18.16.6 Considerations

ASME B18.16.6 specifies selected inch-series prevailing-torque locknuts, including carbon steel nylon-insert hex flange configurations.

The standardized nylon-insert hex flange range begins at 1/4 inch.

Miniature #2 through #10 aluminum flange locknuts should not be represented as standard ASME B18.16.6 hex flange products.

Any inch-series 6061 aluminum version requires a separately approved drawing, material specification and performance requirements.

Metric and UNC/UNF threads are not interchangeable.

Customers should provide the exact thread designation rather than relying on approximate diameter conversion.

How the Nylon-Insert Locking Mechanism Works

The nylon insert is retained near the upper portion of the hexagonal nut.

During installation, the mating bolt thread enters and deforms the nylon insert.

This creates prevailing torque that resists relative rotation between the nut and bolt.

The locking action can help resist rotational loosening in suitably designed vibration-exposed assemblies.

The integrated flange provides a wider bearing surface than a conventional hex nut without a washer.

Key Functional Benefits

• Lightweight 6061 aluminum alloy construction.

• Prevailing-torque resistance to rotational loosening.

• Integrated flange for broader bearing-load distribution.

• Wine red anodized appearance.

• Compact fastening configuration.

• Potential reduction in separate washer handling.

• Suitability for selected weight-sensitive equipment.

• Customizable dimensions and finishes for OEM production.

Prevailing torque does not replace adequate clamp load.

Insufficient joint preload, poor thread engagement or unsuitable mechanical design can still cause loosening or fastening failure.

Installation and Assembly Engineering Guidelines

Thread Compatibility

Confirm the nominal thread diameter, pitch, tolerance and mating bolt specification.

Metric and UNC/UNF thread systems must not be mixed.

Tightening Torque

Aluminum threads may be damaged by excessive tightening.

The correct installation torque depends on the 6061 material temper, thread size, mating bolt, surface finish and joint design.

Generic high-strength steel torque values must not be transferred directly to aluminum lock nuts.

Prevailing Torque and Joint Preload

The nylon insert generates prevailing torque during installation.

The tightening procedure must account for both the prevailing-torque component and the torque required to establish the intended clamp load.

Nylon Insert Engagement

The mating bolt must sufficiently engage the nylon insert.

Thread engagement and bolt protrusion must follow the approved assembly requirements.

Operating Temperature

The nylon insert limits the permissible operating temperature of the complete fastening system.

Temperature capability depends on the nylon grade, exposure duration, mechanical loading and environmental conditions.

The previously stated -50°C to +100°C range should not be treated as a guaranteed service rating without supporting verification.

Reusability

Nylon-insert lock nuts may be reused when permitted by the applicable specification and when locking performance remains acceptable.

Repeated installation can reduce prevailing torque.

Nuts with damaged inserts or distorted aluminum threads should be replaced.

Galvanic Corrosion

Aluminum may experience galvanic corrosion when coupled with dissimilar metals in the presence of moisture.

Mating steel, stainless steel, titanium and copper-alloy components should be evaluated.

Anodizing may provide surface protection, but exposed threads and damaged coating areas can remain vulnerable.

Flange Bearing Surface

The integrated flange provides a wider contact area but does not automatically eliminate local deformation or the need for a washer.

Verify mating surface condition, hole diameter, flange geometry and joint loading.
