ARRMA is renowned for producing high-quality RC cars and trucks, and their genuine spare parts maintain the same exacting standards. This particular item is a pack of two large cap head motor screws, each measuring M3x6mm, designed to fit ARRMA vehicles with motor mounting requirements. The large cap head design is a critical feature that sets this screw apart from standard alternatives, offering superior performance and durability in demanding RC applications.

For anyone maintaining a brushless RC car or electric RC vehicle, having genuine ARRMA spare parts ensures optimal performance and longevity. Whether you are replacing worn screws or building a spare motor assembly, these screws are manufactured to exact specifications and are fully compatible with all ARRMA RC models that require M3x6mm motor fasteners.

Key Features

• Large Cap Head Design — The oversized screw head distributes clamping pressure evenly across a wider surface area, preventing damage to the motor housing and plastic mounting plates whilst providing a secure, safe fitment that resists vibration-induced loosening during high-speed runs.
• Precision M3x6mm Specification — These screws are manufactured to exact metric specifications, ensuring perfect fitment in ARRMA motor mounts and maintaining proper alignment with other chassis components, which is critical for motor stability and vehicle performance.
• Pack of Two — You receive two screws per pack, which is ideal for replacing both sides of a motor mounting assembly or keeping spares in your RC hobby toolkit for future maintenance and repairs.
• Genuine ARRMA Part — As an authentic ARRMA spare part, these screws are engineered to the same quality standards as the original equipment, guaranteeing compatibility and reliability with your RC vehicle.
• Safe and Secure Fastening — The large head eliminates the risk of the screw head sinking into softer plastic components, which is a common problem with standard screws and can lead to loose motors and poor handling characteristics.

Technical Performance

The ARRMA Large Cap Head Motor Screw 3x6mm represents precision engineering for the RC car UK market. Manufactured from hardened steel with a durable finish, these M3x6mm fasteners are designed to withstand the vibrations, impacts and stresses inherent in high-performance RC vehicles. The large cap head is not merely a cosmetic feature—it is a functional engineering solution that addresses a genuine problem in RC vehicle design. When standard screws are used on plastic motor mounts, the smaller head can dig into the material, causing the screw to become loose over time as the plastic creeps and compresses. The larger head distributes the clamping load more evenly, maintaining a consistent, vibration-resistant connection that keeps your motor securely mounted during aggressive acceleration, cornering and jumping. These screws are compatible with ARRMA's range of brushless and brushed RC cars, trucks and buggies, making them a versatile addition to your spares collection. Whether you operate your RC vehicle in dry conditions or encounter muddy terrain, these metal fasteners resist corrosion and maintain their structural integrity throughout multiple seasons of use.

Frequently Asked Questions

• What is the difference between large cap head screws and standard motor screws? — The large cap head design offers a significantly larger surface area beneath the screw head, which distributes the clamping force across a wider area of the motor mount. This prevents the screw head from sinking into plastic components and provides superior vibration resistance compared to standard screws with smaller heads.
• Are these screws compatible with all ARRMA RC vehicles? — These M3x6mm large cap head motor screws are designed specifically for ARRMA RC vehicles that require M3x6mm fasteners for motor mounting. Compatibility depends on your specific model, so we recommend checking your vehicle's manual or parts diagram to confirm the correct screw specification before purchase.
• Will these screws work on my RC car UK setup if I have upgraded the motor? — Yes, these screws are suitable for motor mounting on ARRMA vehicles regardless of whether you are running a standard brushed motor or a higher-performance brushless motor, provided your vehicle's motor plate accepts M3x6mm fasteners.
• How often should I replace my motor screws? — Motor screws should be inspected regularly during maintenance checks and replaced if you notice any signs of wear, corrosion, or damage. It is good practice to replace screws if your motor mount ever becomes loose, as the threads may have become stripped. Keeping spare screws in your RC toolkit ensures you can perform quick replacements without interrupting your driving sessions.
• Is this suitable for beginners? — Yes, these screws are ideal for RC hobbyists of all experience levels. Beginners should find them easy to install using a standard metric Allen key or Phillips head driver, and keeping spares on hand is a sensible approach to RC vehicle maintenance.
• Why is the large cap head important for RC vehicles? — In RC applications, vibration is constantly working to loosen fasteners. The large cap head minimises the risk of the screw head sinking into plastic components, which can cause the connection to loosen over time and potentially lead to motor misalignment and handling issues.
