Product Specifications and Engineering Overview

The listed metric sizes are based on existing product information. 

Exact availability of each size, thread pitch, rainbow finish and twelve-point drive configuration must be confirmed against current manufacturing records.

The original M6 motorcycle description represents one application example rather than the complete scope of the product family.

What Is a Rainbow Titanium 12-Point Flange Nut?

A titanium twelve-point flange nut is an internally threaded fastener featuring an external twelve-point drive and an integrated bearing flange.

The twelve-point drive is also commonly described as a double-hex profile.

Compared with a conventional six-point hex drive, the twelve-point configuration provides additional angular positions for engaging correctly matched tooling.

For the same nominal orientation, a twelve-point profile offers engagement positions at 30-degree intervals, while a six-point profile offers positions at 60-degree intervals.

This can be useful in assemblies where access for repositioning a socket or wrench is limited.

The integrated flange provides a bearing surface beneath the nut and may help distribute the compressive force over a suitable mating component.

Actual performance depends on flange geometry, mating material, thread engagement, assembly preload and operating conditions.

12-Point Drive vs. Conventional Hex Drive

High-Torque Applications: What Engineers Need to Know

Some motorcycle and motorsport buyers search for high-torque 12-point flange nuts.

However, the twelve-point geometry alone does not establish a higher permissible tightening torque.

Allowable torque depends on the complete fastening system.

Important factors include:

• Drive profile geometry.

• Tool engagement dimensions.

• Titanium alloy material condition.

• Internal thread strength.

• Mating bolt material and mechanical properties.

• Thread engagement length.

• Flange bearing pressure.

• Lubrication and friction.

• Required joint preload.

• Dynamic loading and fatigue.

High-torque suitability must be established through the approved design and application-specific testing.

Grade 5 Titanium: Ti-6Al-4V Material Properties

Grade 5 titanium, commonly designated Ti-6Al-4V and UNS R56400, is a titanium alloy containing approximately 6% aluminum and 4% vanadium.

The alloy is valued for its combination of strength-to-weight potential, corrosion resistance and engineering versatility.

The actual mechanical properties depend on the applicable material specification, product form and material condition.

Material Density Comparison

For equal solid metal volume, Grade 5 titanium is approximately 44% lighter than carbon steel.

Actual finished nut weight depends on the component geometry.

Titanium is denser than aluminum but offers a different combination of mechanical properties.

Why OEM Engineers Specify Titanium Fasteners

Potential engineering benefits include:

• High strength-to-weight potential.

• Lower density than steel.

• Corrosion resistance in many environments.

• Compatibility with precision machining.

• Specialized drive geometry.

• Custom flange dimensions.

• Lightweight equipment design.

• Customer-specific manufacturing possibilities.

The material must be selected according to the complete joint requirements rather than appearance or density alone.

Rainbow and Iridescent Titanium Surface Finishes

The featured product has a multicolor metallic appearance with blue, purple, gold, green and other reflective tones.

Common commercial descriptions include:

• Rainbow Titanium.

• Iridescent Titanium.

• Multicolor Titanium.

• Rainbow Finish Titanium.

• Color-Changing Titanium Appearance.

These terms describe the visual appearance rather than a single standardized finishing process.

Titanium Anodizing

Titanium anodizing can produce interference colors associated with controlled oxide-layer formation.

The appearance depends on processing conditions and surface preparation.

Polished Titanium

Polishing changes the surface texture and reflectivity.

It may be used as a preparation step or as a specified final surface condition.

PVD-Coated Titanium

Physical Vapor Deposition is a separate coating process.

Its appearance and functional characteristics depend on the selected coating system.

Other Titanium Coloring Processes

Controlled oxidation and other finishing processes may also produce colored titanium surfaces.

The photograph alone does not establish which process was used.

OEM Rainbow Finish Control

For appearance-sensitive OEM manufacturing, the approved finishing specification should define:

• Required finishing process.

• Approved physical master sample.

• Surface preparation.

• Acceptable color distribution.

• Gloss and reflectivity.

• Cosmetic inspection criteria.

• Coating or oxide requirements.

• Packaging and handling protection.

Rainbow finishes can exhibit differences in color distribution and reflection.

A digital product image should not be the sole acceptance criterion for production color matching.

Metric Thread Sizes and Inch Diameter References

The listed metric sizes are M4, M6, M7, M8, M14, M18 and M20.

The following table provides standard metric coarse-thread references and nominal inch diameter conversions.

The pitches shown are standard metric coarse-thread references, not verified production specifications for every listed nut.

The final pitch, thread tolerance, drive dimensions, flange diameter and nut height must follow the approved engineering drawing.

The inch values are nominal diameter conversions only.

They are not equivalent UNC or UNF thread specifications.

Metric Fine Threads for Custom OEM Projects

Some performance equipment requires metric fine threads rather than standard coarse threads.

Examples of common metric fine-thread designations include M8 × 1.0, M10 × 1.25 and M12 × 1.25.

These are engineering examples, not confirmed standard offerings for this rainbow product.

JUXIN FASTENERS can review customer-specific metric thread requirements according to approved drawings and manufacturing feasibility.

UNC and UNF Thread References for American OEM Customers

American manufacturers may specify Unified National Coarse or Unified National Fine threads.

JUXIN FASTENERS can evaluate custom inch-series titanium flange nut designs based on customer-supplied engineering drawings.

These are standard inch-series thread designations for engineering reference.

They do not imply that all sizes are stocked or currently manufactured.

Important Thread Compatibility Notice

Metric, UNC, UNF, BSW and BSF are different thread systems.

They must not be directly interchanged.

For example, M6 × 1.0 and 1/4-20 UNC are not interchangeable.

Thread compatibility must be established using the actual mating thread designation and tolerance requirements.
