Traxxas 3x8mm Washerhead Machine Screws Motor Mount Set 6 Pieces

Overview

The Traxxas Screws, 3x8mm washerhead machine (large head for motor mount) represent essential replacement components for any serious RC car enthusiast in the UK. Whether you're maintaining a Traxxas Rustler XL, fine-tuning your brushless RC monster truck, or performing routine maintenance on your off-road buggy, these precision-engineered fasteners are indispensable. Designed specifically for motor mount applications, these screws feature the larger washerhead design that distributes load effectively across your motor mounting points, ensuring secure and reliable attachment that will withstand the rigours of competitive racing and weekend bashing alike.

As an authorised Traxxas retailer, RC Model Shop stocks genuine OEM parts that meet Traxxas' exacting quality standards. These screws are manufactured to tolerances that ensure perfect compatibility with your Traxxas RC vehicle, eliminating the frustration of generic fasteners that don't fit quite right. For anyone who takes their RC hobby seriously—whether you're running a ready to run RC car, competing in local races, or building a high-performance custom setup—having the correct replacement parts on hand is crucial. A single worn or stripped screw can compromise your entire motor mount integrity, affecting handling, performance and safety.

The set of six screws provides excellent value, ensuring you have spares available for future maintenance or repair work. Rather than searching for suitable alternatives that might damage your Traxxas components, purchasing genuine Traxxas fasteners guarantees perfect fitment and longevity. These machine screws with Phillips-drive heads make installation and removal straightforward, requiring only a standard Phillips screwdriver or power drill bit.

Key Features

• Large Washerhead Design — The generous washer head on these machine screws distributes fastening pressure across a wider area of your motor mount, preventing the screw head from digging into softer materials and ensuring even load distribution that keeps your motor mount securely fastened under high-torque conditions.
• Precisely Engineered 3x8mm Dimensions — These screws measure exactly 3mm in diameter with an 8mm length, providing the perfect spec for Traxxas motor mount applications and guaranteeing compatibility without the guesswork associated with generic fasteners from non-specialist retailers.
• Phillips-Drive Heads — The Phillips-drive head type allows easy installation and removal using standard Phillips screwdrivers or power drill bits, making maintenance quick and convenient whether you're at the track, at home, or in the field during practice sessions.
• Machine Thread Construction — Unlike self-tapping or wood screws, these machine threads engage with pre-drilled holes in your motor mount with precision, preventing cross-threading and damage that could render your motor mounts unusable.
• Set of Six Pieces — You receive six screws in this pack, providing immediate spares for your current project plus extras for future maintenance, repair work, or experimentation with different mounting configurations on your RC car.
• Silver Finish — The silver-coloured finish provides a professional appearance whilst offering corrosion resistance, maintaining the integrity of your fasteners even when exposed to moisture from wet grass, water crossings, or humid storage conditions typical of UK weather.
• Genuine Traxxas OEM Part — As official Traxxas-manufactured components, these screws are guaranteed authentic and meet all factory specifications, ensuring perfect compatibility and reliability that aftermarket alternatives simply cannot match.

Technical Performance

These 3x8mm washerhead machine screws represent the gold standard in motor mount fastening for Traxxas RC vehicles throughout the UK and beyond. The engineering behind these seemingly simple components is more sophisticated than many casual enthusiasts realise. The washerhead design is crucial because it prevents the relatively small-diameter screw shaft from causing stress concentration in the plastic or composite material of your motor mount. When you tighten a conventional screw head directly into plastic, the concentrated force creates micro-fractures around the hole, gradually weakening the structure until the screw pulls free or the mount cracks entirely. The Traxxas washerhead design eliminates this problem by spreading the clamping force across a much larger surface area. The 3mm diameter provides sufficient strength for transmitting motor torque without being so large that it requires excessive tightening force, which would risk stripping the threads or cracking the motor mount. The 8mm length is precisely calculated to engage adequately with the threaded hole whilst leaving the correct amount of screw shaft in reserve should you need to adjust mounting positions or replace the screw later. The machine thread construction ensures that these screws engage consistently with the threaded inserts in your motor mounts, providing the level of repeatability that competitive racing demands. Whether you're running a high-powered brushless motor on a 4WD off-road buggy or a more modest setup on a ready to run RC car, these fasteners provide the secure mounting foundation your power system requires.

Frequently Asked Questions

• Why should I use genuine Traxxas screws instead of generic fasteners from a DIY store? — Generic fasteners are manufactured to loose tolerances that may result in poor fitment, cross-threading, or stripped threads in your valuable motor mounts. Traxxas screws are engineered specifically for RC applications with tight tolerances that guarantee perfect compatibility. Moreover, genuine parts protect your investment in your RC vehicle and ensure that all components work together as the engineers intended.
• Are these screws suitable for beginners working on their first RC cars? — Yes, absolutely. Whether you're a complete beginner learning to maintain your first ready to run RC car or an experienced competitor, these replacement screws are essential maintenance items. Beginners especially benefit from using genuine OEM parts because they eliminate compatibility uncertainties, allowing you to focus on learning basic maintenance techniques rather than troubleshooting fitment problems.
• What size Phillips screwdriver or drill bit do I need to install these screws? — These screws feature standard Phillips-drive heads, so a standard Phillips screwdriver or Phillips drill bit of appropriate size will work. Most RC mechanics keep a set of precision screwdrivers handy for RC work, and a Phillips bit is invariably included in these sets.
• How many sets of these screws should I keep in stock? — A single set of six screws is typically sufficient for one motor mount replacement. However, many competitive racers and serious enthusiasts keep two or three sets on hand. Since motor mounts are high-wear components subjected to constant vibration and torque, having spare fasteners ensures you're never caught without the correct replacement parts when you need them.
• Will these screws work with my brushless RC motor setup? — Yes, these screws are compatible with both brushed and brushless motor installations. The washerhead design and 3x8mm specification make them suitable for virtually all standard Traxxas motor mounts, regardless of whether you're running a brushed or brushless motor powering your RC car.
• What is the difference between these 3x8mm screws and other sizes? — The 3x8mm specification is optimised specifically for Traxxas motor mounts. Using the wrong size screw risks either insufficient thread engagement (too short) or screws that protrude too far (too long), potentially interfering with motor clearance or other chassis components. Always use the exact size specified for your vehicle.
