Team Associated Blue Aluminium Bulkhead Washers 7.8 x 0.5mm AS31384

Overview

The Associated Blue Aluminium Bulkhead Washers 7.8 x 0.5mm represent an essential hardware component for any serious RC car builder or racer in the UK. These precision-engineered shims are specifically designed for vehicles that utilise bulkhead fasteners and arm mount applications, making them indispensable for both off-road and on-road RC setups. Whether you're building a competition-grade 1/10 scale buggy, assembling a touring car, or maintaining an existing RC model, these bulkhead washers provide the perfect solution for accurate shimming and hardware finishing.

Team Associated is a globally recognised manufacturer of high-quality RC components and complete vehicles, trusted by hobbyists and professional racers alike. This particular product has been engineered to meet the exacting standards that Associated is known for, and these washers are now available as a convenient separate purchase. If you're sourcing spares for your RC car UK collection or building a new model from scratch, having quality bulkhead washers on hand ensures you can achieve proper fitment and a professional appearance on your finished vehicle.

Supplied in a pack of ten pieces, these blue aluminium washers offer excellent value and eliminate the need to purchase entire hardware kits when you only need the washers. The distinctive blue colour provides a neat aesthetic finish that complements the anodised components found on many Associated RC vehicles, and the large outside diameter design makes them suitable for a wide range of applications across the entire Associated vehicle lineup.

Key Features

• Premium Aluminium Construction — Manufactured from quality aluminium material, these washers are lightweight yet durable, providing reliable performance in demanding RC applications without adding unnecessary weight to your vehicle.
• Professional Blue Anodised Finish — The distinctive blue colour provides a neat, finished appearance to your RC car builds and matches the aesthetic of many Associated anodised components, giving your vehicle a factory-quality look.
• Large Outside Diameter Design — The 7.8mm outer diameter provides excellent surface coverage for bulkhead mounting and arm shimming applications, distributing load effectively across mounting points and preventing fasteners from pulling through plastic or composite materials.
• Precise 0.5mm Thickness — Manufactured to exact specifications, the 0.5mm thickness is ideal for fine adjustment and shimming requirements in both off-road buggies and on-road touring cars, allowing you to achieve perfect alignment and eliminate slop in critical areas.
• Pack of Ten Units — This generous quantity ensures you have sufficient washers for complete builds or to maintain a spare stock for future projects and repairs, reducing the need for multiple purchases.
• Universal Compatibility — These washers are designed to work with a vast range of Associated 1/10 scale vehicles, from classic models through to the latest racing platforms, making them a versatile addition to your RC spares collection.
• Off-Road and On-Road Applications — Suitable for shimming bulkhead mounts in both off-road short course trucks, stadium trucks and buggies as well as on-road touring cars, these washers are truly multipurpose hardware components.

Technical Performance

These bulkhead washers represent the kind of precision engineering that Associated has built its reputation upon. Manufactured from quality aluminium and finished in an anodised blue coating, they offer excellent durability whilst maintaining a lightweight profile essential in competitive RC racing. The 7.8 x 0.5mm dimensions have been carefully specified to work across the entire Associated vehicle range, providing adequate surface coverage at bulkhead mounting points and arm attachment areas without introducing excessive thickness that could affect clearances or alignment. The large outside diameter is particularly important in RC car construction, as it distributes the clamping force across a wider area of the chassis or arm, preventing fasteners from pulling through softer materials and ensuring long-term reliability even under the demanding conditions faced by competitive racers. Whether you're building a precision on-road touring car where alignment tolerances are measured in fractions of millimetres, or assembling a robust off-road short course truck designed to handle aggressive bashing, these washers provide the quality and precision you need. The blue anodised finish is not merely decorative; the anodising process creates a protective layer that resists corrosion and wear, ensuring these washers will maintain their appearance and functionality through multiple seasons of racing and recreational use.

Frequently Asked Questions

• What are bulkhead washers and why do I need them for my RC car? — Bulkhead washers are shims designed to provide proper spacing and load distribution at critical mounting points on your RC vehicle. They prevent fasteners from pulling through composite or plastic chassis and arms, whilst also allowing for precise shimming and adjustment of alignment. In competitive RC racing and serious building, proper shimming is essential for achieving optimal suspension geometry, eliminating slop in arm mounts, and ensuring your vehicle handles correctly.
• Will these washers fit my Associated RC car? — Yes, these washers are designed to be compatible with an extensive range of Associated 1/10 scale vehicles, including all major buggy platforms such as the RC10B6 series, latest touring cars like the TC7.2, and short course trucks including the SC10 range. If your vehicle uses bulkhead fasteners, these washers will almost certainly be suitable, though we recommend checking your vehicle's manual or contacting our expert team if you're uncertain about compatibility.
• What is the difference between 0.5mm and other washer thicknesses? — Washer thickness is critical in RC vehicle building because it directly affects suspension geometry, arm angle, and overall alignment. The 0.5mm thickness is designed for fine adjustment and shimming in areas where precise tolerances matter. Associated offers washers in different thicknesses as part of their shimming system, allowing racers to achieve the exact adjustments their vehicles need. If you require different thicknesses for your specific application, we stock the complete range of Associated shims.
• Are these washers suitable for both on-road and off-road RC vehicles? — Absolutely. These bulkhead washers are equally at home in precision on-road touring car applications where alignment is critical, and in rugged off-road buggies and short course trucks where durability is paramount. The aluminium construction is strong enough to handle the demands of both applications, and the large 7.8mm outside diameter provides adequate surface coverage regardless of whether you're running a high-speed tarmac racer or an aggressive basher.
• How many washers do I need for a complete build? — This depends entirely on your vehicle and how extensively you plan to shim it. A typical build might use anywhere from four to ten washers at various mounting points, including bulkhead mounts, suspension arms, and other critical areas. This pack of ten provides enough for a complete build with spares remaining, which is ideal for having backup hardware on hand for maintenance and repairs.
• Can I use these washers with fasteners from other manufacturers? — These washers are designed to work with standard metric fasteners commonly used in RC vehicles. However, we always recommend verifying that your fasteners are compatible with the 7.8mm outside diameter to ensure proper fit and function. If you're unsure about fastener compatibility, our expert team at RC Model Shop is happy to help you source the correct components.
• What makes Team Associated hardware superior to generic alternatives? — Team Associated components are engineered to exact specifications and manufactured to rigorous quality standards. The blue anodised finish is not merely cosmetic; the anodising process creates a protective layer that resists corrosion and wear, ensuring longevity and reliable performance. Associated's precision engineering ensures these washers will perform consistently through multiple seasons of use, whether you're racing competitively or enjoying recreational bashing.
