Product Specification
Peach Pink Anodized 6061 Aluminum Nylon-Insert Lock Nuts
Custom Color-Matched Lightweight Locknuts for Bicycle Accessories, Motorcycle Components, Motorsport Equipment and OEM Manufacturing
JUXIN FASTENERS manufactures custom industrial fasteners for OEM, Tier-1 and Tier-2 manufacturers, mechanical engineers, production managers and international procurement teams.
Our peach pink anodized 6061 aluminum nylon-insert hex lock nuts combine a lightweight aluminum alloy body with a retained non-metallic locking insert and a distinctive metallic pink finish.
The product is intended for suitable assemblies where visible hardware, controlled color appearance, reduced component mass and prevailing-torque performance are relevant to the finished design.
Unlike standard silver industrial locknuts, this version emphasizes customer-approved anodized color matching for branded bicycle accessories,
mountain bike equipment, motorcycle components and specialized mechanical products.
The locking insert creates rotational resistance when engaged by a mating threaded fastener.
This feature can help resist unintended loosening when the complete joint has been correctly engineered and assembled.
JUXIN FASTENERS supports OEM/ODM custom manufacturing, CNC machining, made-to-drawing components, approved surface finishes and industrial batch production.

Why Peach Pink Aluminum Locknuts Are Different
Peach pink is a specialized anodized appearance that may be selected by bicycle accessory brands, motorcycle equipment manufacturers and producers of customized mechanical products.
Its commercial value is primarily associated with coordinated product appearance.
However, the fastener must also satisfy the functional requirements of the assembly.
For OEM engineering teams, product selection involves three separate decisions:
Is aluminum alloy 6061 mechanically suitable for the joint?
Does the nylon insert provide the required prevailing-torque performance?
Can the anodized finish meet the approved appearance and production requirements?
A successful design must address all three.
Peach Pink vs. Coral Pink vs. Rose Gold
These terms are sometimes used inconsistently in commercial fastener listings.
| Color Description | General Appearance | Procurement Consideration |
|---|---|---|
| Peach Pink | Warm pink with peach or orange influence | Recommended Primary Description |
| Coral Pink | Pink with stronger orange-red influence | Related Search Term |
| Salmon Pink | Muted pink-orange | Alternative Visual Description |
| Rose Gold | Metallic pink-gold appearance | Not Automatically Equivalent |
| Fuchsia | Strong pink-magenta | Different Color Family |
The actual product color should be determined by an approved physical master sample.
A photograph or color name alone is not a sufficient acceptance specification.
Anodized Color Matching for OEM Bicycle and Motorcycle Brands
Anodized aluminum finishes may vary according to material and processing conditions.
For branded accessory manufacturing, color consistency is especially important when several components are installed together.
A customer may require matching fasteners, brackets, decorative hardware and other anodized aluminum parts.
However, identical processing conditions do not always produce identical appearance across different alloys or surface textures.
Recommended OEM Color Approval Process
| Stage | Required Information | Engineering Purpose |
|---|---|---|
| Design Review | Product Drawing and Material | Confirm Component Feasibility |
| Color Definition | Physical Master Sample | Establish Appearance Target |
| Sample Evaluation | Prototype or Production Sample | Review Color and Geometry |
| Finish Approval | Approved Anodizing Requirements | Establish Process Expectations |
| Production Inspection | Agreed Appearance Criteria | Evaluate Batch Consistency |
| Packaging Review | Surface Protection Requirements | Reduce Cosmetic Damage |
Where appearance is important, customers should specify the inspection lighting, viewing conditions and acceptable variation.
A digital image should not be the sole color acceptance reference.
Polishing, Anodizing and PVD: Different Manufacturing Processes
Polishing is a mechanical surface preparation process that changes surface texture and reflectivity.
Anodizing is an electrochemical process that forms an oxide layer on aluminum.
PVD is a separate coating process involving deposition of material onto a surface.
These processes are not interchangeable.
The actual manufacturing and finishing route must be specified for each order.
6061 Aluminum Alloy: Material Engineering
6061 is an aluminum-magnesium-silicon alloy used in many machined components.
Its low density is relevant to lightweight equipment design.
However, mechanical strength depends on the alloy temper and processing condition.
6061-T6, for example, must not be treated as mechanically identical to annealed 6061.
The required material temper should be identified on the drawing or purchase specification.
Material Density Reference
| Material | Approximate Density |
|---|---|
| Aluminum Alloy 6061 | 2.70 g/cm³ |
| Grade 5 Titanium Alloy | 4.43 g/cm³ |
| Carbon Steel | 7.85 g/cm³ |
| Stainless Steel | 7.9–8.0 g/cm³ |
For equal solid metal volume, 6061 aluminum is approximately 66% lighter than carbon steel.
Actual nut weight depends on geometry.
Lower density does not establish equal loadability.
How the Nylon-Insert Locking Feature Works
The nut contains a retained polymer insert positioned to engage the mating bolt.
During installation, the bolt thread locally deforms the insert.
This creates resistance to rotation, known as prevailing torque.
Prevailing torque is not the same as the torque required to produce joint preload.
Engineers should consider both values when establishing an installation procedure.
The locking performance depends on the insert design, polymer formulation, mating bolt, thread tolerances, temperature, lubrication and reuse history.
Nylon-Insert vs. All-Metal Prevailing-Torque Nuts
A nylon-insert locknut uses polymer-to-thread interference.
An all-metal prevailing-torque locknut uses controlled metallic deformation.
These are different locking systems.
Selection should account for operating temperature, mechanical loading, chemical exposure, reuse and assembly requirements.
Metric Thread Sizes and Inch Diameter References
The listed metric product family includes M3, M4, M5, M6, M8, M10 and M12.
| Metric Thread | Standard Coarse Pitch | Nominal Diameter in Inches |
|---|---|---|
| M3 | 0.50 mm | 0.1181 in |
| M4 | 0.70 mm | 0.1575 in |
| M5 | 0.80 mm | 0.1969 in |
| M6 | 1.00 mm | 0.2362 in |
| M8 | 1.25 mm | 0.3150 in |
| M10 | 1.50 mm | 0.3937 in |
| M12 | 1.75 mm | 0.4724 in |
These are standard metric coarse-thread references.
Actual thread pitch, tolerance and product availability must be verified.
The inch values represent nominal diameter conversions only.
They do not represent interchangeable American thread sizes.
Metric Fine-Thread Engineering Options
Custom metric fine-thread requirements may be evaluated.
Examples include M6 × 0.75, M8 × 1.0, M10 × 1.25 and M12 × 1.25.
These are engineering examples rather than confirmed stock specifications.
UNC and UNF Threads for American OEM Manufacturing
JUXIN FASTENERS can evaluate custom American inch-series thread designs according to customer drawings.
| Nominal Size | UNC | UNF |
|---|---|---|
| #4 | #4-40 | #4-48 |
| #6 | #6-32 | #6-40 |
| #8 | #8-32 | #8-36 |
| #10 | #10-24 | #10-32 |
| 1/4 in | 1/4-20 | 1/4-28 |
| 5/16 in | 5/16-18 | 5/16-24 |
| 3/8 in | 3/8-16 | 3/8-24 |
| 7/16 in | 7/16-14 | 7/16-20 |
| 1/2 in | 1/2-13 | 1/2-20 |
| 9/16 in | 9/16-12 | 9/16-18 |
| 5/8 in | 5/8-11 | 5/8-18 |
| 3/4 in | 3/4-10 | 3/4-16 |
These are recognized thread designations for engineering reference.
They do not imply that every combination is stocked or already qualified for manufacture.
Important Thread Compatibility Notice
