Titanium Grey Means Color – Not Titanium Alloy

Titanium grey describes the anodized surface appearance.

The nut body is 6061 aluminum alloy. It is not manufactured from titanium metal or titanium alloy.

The product should not be confused with titanium fasteners, titanium-coated steel nuts or titanium nitride-coated components.

Titanium grey, titanium gray, metallic grey and gunmetal grey may be used as descriptive search terms, but they are not automatically identical color specifications.

Where appearance is critical, the final anodizing shade should be established using an approved physical reference sample.

6061 Aluminum Alloy: Lightweight Material for Precision Fastener Manufacturing

6061 aluminum is a magnesium-silicon aluminum alloy widely used in machined components, transportation equipment and lightweight mechanical assemblies.

It offers a useful combination of low density, machinability and corrosion resistance for appropriately engineered fastening applications.

Weight Reduction

The typical density of 6061 aluminum is approximately 2.70 g/cm³.

Carbon steel has a typical density of approximately 7.85 g/cm³.

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

The actual weight difference between finished lock nuts depends on the flange diameter, overall height, thread dimensions and nylon insert.

For weight-sensitive bicycle accessories, motorsport equipment, drones and robotics, engineers may evaluate aluminum fastening components where the mechanical requirements permit their use.

Material Temper and Mechanical Performance

6061 aluminum is available in different material conditions.

The alloy designation alone does not establish a specific tensile strength, proof-load capacity, fatigue performance or thread stripping resistance.

6061-T6 is a particular heat-treated condition and must not be assumed without supporting material documentation.

For custom OEM manufacturing, the customer should identify the required temper and mechanical acceptance criteria.

Aluminum nylon-insert lock nuts must not automatically replace high-strength steel lock nuts in structural or safety-critical joints.

Machinability and Dimensional Control

6061 aluminum is suitable for many precision-machined mechanical components.

For custom locknut manufacturing, the approved drawing should define:

  • Nominal thread size and pitch.

  • Thread tolerance.

  • Nut height.

  • Width across flats.

  • Flange diameter and thickness.

  • Bearing surface requirements.

  • Nylon insert geometry and retention.

  • Surface treatment requirements.

  • Mechanical and functional acceptance criteria.

Manufacturing feasibility and inspection requirements should be reviewed before bulk production.

Titanium Grey Anodizing for OEM Equipment Manufacturing

Titanium grey anodizing provides a metallic grey appearance for equipment manufacturers seeking coordinated component finishes.

The color can complement precision-machined aluminum parts, bicycle accessories, robotics equipment, industrial instruments and specialty mechanical products.

The anodized oxide layer can also provide surface protection when the process is correctly specified.

However, anodizing color alone does not establish superior strength, locking performance or corrosion resistance.

OEM Color Matching and Anodizing Consistency

Color consistency is important for manufacturers assembling visible hardware into finished products.

For repeatable OEM production, JUXIN FASTENERS can review customer requirements for:

  • Titanium grey color references.

  • Approved physical master samples.

  • Surface preparation.

  • Anodizing process specifications.

  • Coating thickness.

  • Surface sealing.

  • Appearance and cosmetic acceptance criteria.

  • Color consistency between manufacturing batches.

  • Scratch protection during packaging.

  • Outdoor exposure requirements where applicable.

Actual anodizing appearance may vary with alloy condition, surface preparation, process parameters and lighting.

For color-sensitive programs, customers should approve a physical sample before bulk production.

Titanium Grey vs. Black, Silver and Other Anodized Colors

This product belongs to the same 6061 aluminum nylon-insert flange locknut family as other anodized color versions.

The underlying fastening design, material requirements and locking mechanism remain consistent unless the approved engineering specification states otherwise.

Titanium grey is selected for its metallic grey appearance.

Black, silver, gold, green, purple and other colors serve different appearance requirements.

A change in decorative color does not automatically change the mechanical strength or prevailing-torque performance of the fastener.

For manufacturers using several anodized colors in one product family, consistent drawings and clearly defined color codes can help reduce purchasing and assembly errors.

Metric Thread Sizes M2–M16

The listed product range includes M2, M2.5, M3, M4, M5, M6 and M8.

Metric ThreadStandard Coarse Pitch (mm)
M20.40
M2.50.45
M30.50
M40.70
M50.80
M61.00
M81.25

These are standard metric coarse-thread pitch references.

Actual dimensions, thread tolerances and nylon insert geometry must follow the approved manufacturing drawing.

M2–M4 Miniature Aluminum Lock Nuts

M2, M2.5, M3 and M4 configurations may be considered for compact instruments, miniature robotics, RC racing equipment and lightweight mechanical accessories.

Small aluminum threads require careful torque control and appropriate thread engagement.

M5–M8 Aluminum Lock Nuts

M5, M6 and M8 configurations may be evaluated for selected bicycle accessories, motorsport equipment mounts, machinery covers and lightweight industrial brackets.

The thread diameter alone does not establish suitability for high-load or safety-critical applications.

Titanium Grey Anodized 6061 Aluminum Nylon-Insert Hex Flange Lock Nuts

UNC and UNF Inch-Series Thread References for US OEM Manufacturing

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

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

Nominal Inch SizeUNC ThreadUNF Thread
#2#2-56 UNC#2-64 UNF
#4#4-40 UNC#4-48 UNF
#6#6-32 UNC#6-40 UNF
#8#8-32 UNC#8-36 UNF
#10#10-24 UNC#10-32 UNF
1/4"1/4-20 UNC1/4-28 UNF
5/16"5/16-18 UNC5/16-24 UNF

These thread designations are provided for custom OEM engineering inquiries.

They are not confirmation of existing inventory or established production specifications for this titanium grey aluminum locknut.

Custom inch-series manufacturing requires review of:

  • Thread designation and tolerance.

  • Mating bolt requirements.

  • Aluminum material and temper.

  • Flange geometry.

  • Nylon insert design.

  • Prevailing-torque performance.

  • Production quantity and tooling feasibility.

  • Inspection and acceptance criteria.

Metric and UNC/UNF threads are not interchangeable.

Similar nominal diameters do not establish thread compatibility.

How Nylon-Insert Prevailing-Torque Lock Nuts Work

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

During installation, the mating bolt engages the nylon insert and creates controlled interference.

This interference generates prevailing torque, which resists relative rotation between the nut and bolt.

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

Functional Advantages

  • Lightweight 6061 aluminum alloy construction.

  • Prevailing-torque resistance to rotational loosening.

  • Integrated flange bearing surface.

  • Titanium grey anodized appearance.

  • Compact fastening configuration.

  • Potential reduction in separate washer handling.

  • Custom dimensions for OEM assemblies.

  • Color-matched hardware for industrial products.

Prevailing torque does not replace adequate joint preload.

Correct tightening, thread engagement, bearing stress and mechanical design remain essential.

Installation and Assembly Engineering Guidelines

Tightening Torque

Aluminum threads may be damaged by excessive tightening.

Installation torque must be established from the actual 6061 material temper, thread size, mating bolt, surface condition and joint requirements.

High-strength steel fastener 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 locking resistance and the torque required to establish the intended clamp load.

Thread Engagement

The mating bolt must engage the nylon insert sufficiently to establish the required locking function.

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 load and environment.

A service range such as -50°C to +100°C must not be guaranteed without supporting material and performance verification.

Reusability

Reuse may be possible when permitted by the approved specification and when prevailing-torque performance remains acceptable.

Repeated installation can reduce locking resistance.

Damaged nylon inserts or aluminum threads require replacement.

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 does not eliminate corrosion risk at exposed or damaged areas.

Flange Bearing Surface

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

Engineers should verify bearing stress, hole diameter, mating surface condition and flange geometry.
