Fastrax M3 Flat Washer Blue 1.5mm RC Hardware Pack of 6 FAST142-3

Overview

The Fastrax M3 Flat Washer Blue 1.5mm (6) FAST142-3 is an essential hardware component for RC enthusiasts across the UK who demand precision engineering and reliability in their builds. Whether you're tuning a Traxxas RC car, maintaining an ARRMA off-road buggy, or working on any scale RC model that utilises M3 fasteners, these flat washers are indispensable for achieving professional-grade assembly standards. Fastrax has established itself as a trusted manufacturer of quality option parts and hardware for the RC hobby community, and these washers exemplify their commitment to precision engineering.

Flat washers serve a critical function in RC model assembly—they distribute the load of screws and bolts across a wider surface area, preventing fasteners from pulling through softer materials and creating secure, lasting connections in your RC vehicle. For builders working on everything from RC crawlers to drift cars, trophy trucks to on-road racing machines, having the correct hardware specification makes the difference between a reliable setup and frustrating mechanical failures. These M3 washers are manufactured to exacting standards to ensure consistent performance across your RC builds.

RC Model Shop stocks a comprehensive range of Fastrax option parts and hardware designed to help you maintain, upgrade and customise your RC vehicles to the highest standards. As a dedicated RC retailer serving customers throughout the UK, we understand the importance of quality fasteners and replacement parts in keeping your RC hobby enjoyable and your vehicles performing at their best.

Key Features

• Correct M3 Specification — These washers are precisely engineered to the M3 metric standard, ensuring they work seamlessly with M3 fasteners and parts commonly used throughout the RC industry in models from manufacturers like Traxxas, Team Associated, Losi and more. Using the correct washer specification prevents cross-threading and ensures proper load distribution.
• 1.5mm Thickness — The 1.5mm thickness provides optimal balance between structural support and minimal weight addition to your RC model. This specification is designed specifically for precision RC applications where every gram matters for performance and handling characteristics.
• Blue Anodised Finish — The blue anodised coating provides corrosion resistance and extends the service life of these washers, particularly important for RC vehicles that may be exposed to moisture during outdoor use or wet weather conditions common across UK climate zones. The anodised finish also gives your RC build a professional, polished appearance.
• Pack of Six — Each package contains six washers, providing enough hardware for multiple assembly projects or offering spare parts for future builds and maintenance of your RC collection. Six washers covers typical small-scale repair and upgrade scenarios in RC hobbyist workshops.
• Genuine Fastrax Option Parts — These washers are authentic Fastrax manufactured components, ensuring they meet the exact specifications and quality standards expected by serious RC enthusiasts who demand reliable, properly engineered hardware for their vehicles.

Technical Performance

The Fastrax M3 Flat Washer Blue 1.5mm represents precision engineering optimised for RC applications. With an M3 metric thread specification, these washers are compatible with the vast majority of fastener systems used throughout the RC hobby—from scale crawlers and rock crawlers requiring robust hardware, to high-speed RC buggies and off-road trucks needing lightweight yet durable components. The 1.5mm thickness has been engineered to provide sufficient bearing surface for secure fastening without contributing unnecessary weight that would negatively impact acceleration, handling and speed characteristics in competitive or recreational RC racing. The blue anodised aluminium construction offers superior corrosion resistance compared to raw steel or bare aluminium, making these washers ideal for outdoor RC use across varying UK weather conditions including damp environments, coastal locations, and winter storage scenarios. The anodisation process creates a hard, protective oxide layer that resists scratching and maintains appearance through repeated assembly and disassembly cycles typical in the maintenance and upgrading phases of RC ownership. Each washer is manufactured to exacting tolerances ensuring consistent inner and outer diameters that prevent binding, cross-threading or excessive play when assembled with precision M3 fasteners.

Frequently Asked Questions

• What size fasteners do these M3 washers fit? — These washers are designed specifically for M3 metric fasteners, which are commonly found across RC cars, trucks, buggies and other hobby-grade vehicles. M3 refers to a 3-millimetre nominal diameter thread size used extensively throughout the RC industry for assembling chassis components, electronics mounts, suspension links and general hardware applications.
• Why should I use washers when assembling my RC car? — Flat washers distribute the clamping force of a bolt or screw across a wider surface area, preventing the fastener from pulling through softer materials like plastic, composite chassis plates or anodised aluminium bodies. This is particularly important in RC models where lightweight materials are prioritised and preventing stripped screw holes or material damage ensures the longevity and reliability of your vehicle.
• Will these washers work with my Traxxas RC truck? — Many Traxxas models and other major RC manufacturers use M3 fasteners in their designs. These Fastrax washers are compatible with any RC vehicle that utilises M3 specification fasteners, making them suitable for use as replacement or upgrade parts across multiple brands and model types in your RC collection.
• What is the benefit of the blue anodised coating? — The blue anodised finish provides excellent corrosion resistance, protecting the underlying aluminium from oxidisation and rust particularly important for RC enthusiasts in the UK where moisture exposure is common. The anodised coating also creates a harder surface that resists scratching through repeated assembly and disassembly, and gives your RC build a professional, finished appearance.
• How many washers do I need for my RC project? — This pack contains six washers which is sufficient for most small-scale repair, upgrade or assembly projects. For larger builds or those requiring multiple fastening points, you may wish to order additional packs to ensure adequate inventory for your RC workshop.
