Traxxas Motor Screws 3x8mm Washerhead Machine Phillips Drive Pack of 6 TRX3185

Overview

The Traxxas Motor screws (3x8mm washerhead machine) TRX3185 are essential replacement fasteners for RC enthusiasts maintaining and upgrading their Traxxas vehicles. Whether you're a seasoned RC racer, weekend basher, or dedicated hobbyist, having quality replacement screws on hand is crucial for keeping your RC car UK-ready and performing at its best. These precision-engineered motor screws are specifically designed to secure your motor to the motor plate with reliable, consistent holding power, ensuring your brushless or brushed motor stays firmly in place during high-speed runs and intense off-road action.

As a critical component in RC car maintenance, these washerhead machine screws represent the kind of small-but-mighty parts that separate a well-maintained RC vehicle from one that's prone to mechanical issues. The set of six screws provides you with plenty of spares for multiple RC models or for keeping backups in your toolbox for race days and casual driving sessions. Traxxas is recognised globally as a leader in RC innovation and quality, and their fastening solutions are engineered to the same high standards as their vehicles, transmitters, and electronics. If you're running a Traxxas RC truck, buggy, or crawler, genuine Traxxas motor screws ensure compatibility and longevity.

These 3x8mm washerhead machine screws are the OEM (original equipment manufacturer) fasteners found on countless Traxxas models, making them one of the most universally useful spare parts any RC enthusiast can stock. From the iconic Traxxas Rustler and Slash platforms to the advanced TRX-4 crawler range, these screws play a vital role in motor mounting. Whether you're refreshing worn fasteners, replacing lost screws, or simply maintaining a complete spares collection, the TRX3185 offers genuine Traxxas quality at a competitive price.

Key Features

• Washerhead Design — The integrated washer head spreads the clamping force across a larger surface area, preventing the screw head from digging into softer materials and reducing the risk of stripping the motor mounting area during installation or removal.
• Phillips-Drive Head — The Phillips-drive head is compatible with standard Phillips screwdrivers and RC tool sets, making installation and removal straightforward without requiring specialised equipment or hex keys.
• Machine Thread Profile — Machine threads (as opposed to wood screws) provide consistent, reliable engagement in pre-drilled holes, ensuring repeatable torque specifications and preventing over-tightening that could damage your motor mounting plate.
• M3 Metric Size — The M3 (3mm) diameter and 8mm length are precision-engineered dimensions that match Traxxas OEM specifications exactly, guaranteeing perfect fit on Traxxas motor plates without modification or adaptation.
• Set of Six Screws — Six screws provide enough fasteners for complete motor mounting on most Traxxas vehicles, plus spares for your RC car UK spares box, ensuring you're never caught without critical fasteners when you need them most.
• Genuine Traxxas OEM Parts — As official Traxxas replacement parts, these screws are manufactured to factory specifications and quality standards, ensuring compatibility with all Traxxas models that use 3x8mm washerhead motor screws.
• Durable Material Construction — The screws are manufactured from high-quality steel that resists corrosion and maintains consistent clamping force over time, even after multiple installations and removals during maintenance cycles.
• Affordable Multi-Pack — Buying six screws together is more economical than purchasing individual fasteners, making this set perfect for keeping in your pit bag or toolbox for emergency repairs and preventative maintenance.

Technical Performance

The Traxxas Motor screws TRX3185 represent precision fastening engineering designed specifically for the demanding environment of RC vehicles. With their M3 metric thread profile and 8mm length, these screws are engineered to provide secure, repeatable motor mounting on the motor plates found across the Traxxas range. The washerhead design is critical to performance — it distributes clamping loads across a wider surface area than a standard machine screw head, which is essential when mounting lightweight composite or aluminium motor plates that could otherwise suffer surface damage or compression from a small-diameter screw head. The Phillips-drive head accepts any standard Phillips screwdriver, making them accessible to RC hobbyists of all experience levels, from beginners learning basic maintenance to experienced competitors managing pit equipment at UK RC racing events. The machine thread specification ensures that screws inserted into properly drilled and tapped holes will seat consistently, providing the kind of reliable fastening that keeps your motor aligned and secure during high-acceleration launches, cornering loads, and the vibration cycles inherent to RC motorsport. Whether you're running a brushless motor on a high-speed short course truck, a brushed motor in a vintage RC crawler, or any Traxxas model in between, these screws maintain their grip through countless heat cycles and mechanical stresses. The set of six provides complete motor mounting for most Traxxas vehicles (typically requiring four screws) plus two spares, making this an economical choice for maintaining multiple RC cars or keeping backups on hand for competition days.

Frequently Asked Questions

• What are these Traxxas motor screws used for? — These 3x8mm washerhead machine screws are specifically designed to secure your brushless or brushed motor to the motor mounting plate on your Traxxas RC vehicle. They provide the critical fastening that keeps your motor properly aligned and prevents it from shifting during acceleration, braking, or high-speed cornering.
• How many screws are in this set? — This set includes six screws, which is enough to mount a motor on most Traxxas vehicles (typically requiring four fasteners) plus two spare screws for replacement or backup use.
• Are these compatible with all Traxxas RC cars? — These screws are compatible with any Traxxas vehicle that uses 3x8mm washerhead machine motor screws. This includes many popular Traxxas models including the Rustler, Slash, Stampede, and various TRX-4 crawler models. Check your vehicle's parts list to confirm compatibility with your specific model.
• What is the difference between washerhead screws and regular machine screws? — Washerhead machine screws have an integrated flat washer built into the head, which spreads the clamping force across a larger area of the motor mounting plate. This prevents the screw head from digging into soft materials and protects the mounting surface from damage during tightening or repeated removal.
• What tools do I need to install these screws? — These screws feature Phillips-drive heads, so you'll need a Phillips screwdriver (size #1 or #2 typically works best for M3 fasteners). No specialised RC tools or hex keys are required, making installation accessible to any RC enthusiast.
• Are these original Traxxas parts? — Yes, these TRX3185 motor screws are genuine original equipment manufacturer (OEM) Traxxas parts, manufactured to factory specifications and quality standards. When you buy genuine Traxxas fasteners, you're guaranteed compatibility and reliability.
• How tight should I tighten these screws? — Tighten washerhead machine screws until the washer head contacts the motor mounting plate and seats firmly, then turn an additional quarter turn. Do not over-tighten, as this can damage the motor plate or strip the threads. If you're replacing stripped screws, you may need to move the mounting hole or use the next larger screw size.
• Can I use these screws for anything else on my RC car? — While these screws are specifically designed for motor mounting, they can theoretically be used for other 3mm mounting applications on your RC vehicle. However, for best results, always use the fasteners specified in your vehicle's assembly manual or parts list.
