Overview
The Fastrax M3 Black Nyloc Locknuts (4PCS) FASTM3BK are essential spare parts for RC enthusiasts who demand reliability and durability in their hobby setups. These precision-engineered locknuts are specifically designed to keep your RC car components securely fastened during intense driving sessions, whether you're bashing on UK terrain or competing at your local RC track. If you own an FTX RC vehicle or any other model that requires M3 fasteners, these black nyloc locknuts are an invaluable addition to your spare parts collection.
Locknuts are a critical component in any RC car, providing a self-locking mechanism that prevents fasteners from vibrating loose during operation. The nylon insert in these M3 locknuts creates friction that holds the bolt in place without requiring you to over-tighten, which could damage threads or components. For RC car enthusiasts in the UK who want to maintain their vehicles properly and ensure every nut and bolt stays exactly where it should be, these Fastrax locknuts represent a smart investment in performance and reliability.
This pack of four M3 black nyloc locknuts offers outstanding value for money and ensures you always have spares on hand. Whether you're maintaining your trophy truck, buggy, or any other RC vehicle, having quality locknuts in your spares box is fundamental to keeping your RC car running smoothly and safely.
Key Features
- M3 Thread Size — These locknuts are precisely sized at M3, making them compatible with a wide range of RC vehicle fastening points and ensuring a perfect fit on your components without the risk of cross-threading or loose connections.
- Nyloc Design — The nylon insert built into these locknuts provides a self-locking mechanism that prevents vibration-induced loosening, which is absolutely critical for RC vehicles that experience constant movement, acceleration and braking.
- Black Finish — The black colour coating gives these locknuts a professional appearance whilst also providing a degree of corrosion resistance, helping them maintain their integrity even when exposed to the elements during outdoor RC driving sessions.
- Flanged Design — The flanged construction of these locknuts provides a larger bearing surface, distributing clamping force more effectively across fastening points and reducing the risk of damage to soft materials or components.
- Pack of Four — Four locknuts in each pack means you have multiple spares available, allowing you to replace worn or damaged locknuts across multiple fastening points on your RC vehicle without needing to order additional packs.
- Fastrax Quality — Manufactured by Fastrax, a trusted name in RC spare parts, these locknuts are engineered to exacting standards and reliability that RC enthusiasts depend on for their vehicles.
Technical Performance
These Fastrax M3 Black Nyloc Locknuts are manufactured to precise engineering tolerances that ensure compatibility with standard M3 fastening points found on most RC vehicles. The nylon insert inside each locknut creates a friction-based self-locking mechanism that prevents loosening caused by vibration, a critical requirement for any RC car that experiences constant acceleration, deceleration and directional changes during operation. The flanged design provides a wider bearing surface than standard locknuts, which means the clamping force is distributed over a larger area, reducing the likelihood of damaging softer materials or pushing fasteners through component holes. The black finish provides both aesthetic appeal and enhanced corrosion resistance compared to bare metal, making these locknuts suitable for use in various weather conditions and environments. Whether you're maintaining an FTX Zorro Trophy Truck or any other RC vehicle, the quality engineering behind these locknuts ensures that your vehicle's critical fastening points remain secure throughout extended driving sessions, training runs, or competitive events across the UK.

Frequently Asked Questions
- What does nyloc mean in RC locknuts? — Nyloc refers to the nylon insert inside the locknut that creates friction when bolts are threaded through. This friction prevents the bolt from vibrating loose during RC car operation, which is why nyloc locknuts are standard in the RC hobby. Without the nylon insert, regular locknuts can gradually work themselves loose as your RC vehicle drives over bumps, turns, and experiences vibration from the motor.
- Are these locknuts compatible with my RC vehicle? — These M3 black nyloc locknuts are confirmed compatible with the FTX5556B FTX Zorro Trophy Truck Brushed RTR in Blue and the FTX5557WO FTX Zorro Trophy Truck Brushless RTR in Orange. They will also fit any other RC vehicle that uses M3 fastening points, making them a versatile spare part for most RC cars and trucks available in the UK.
- Why should I use locknuts on my RC car instead of regular nuts? — Regular nuts can vibrate loose over time due to the constant movement and vibration your RC vehicle experiences during operation. Nyloc locknuts feature a nylon insert that creates friction and prevents this vibration-induced loosening without requiring you to over-tighten, which could strip threads or damage components. This makes them essential for maintaining the structural integrity and safety of your RC vehicle.
- How many locknuts do I need? — This pack contains four locknuts, which should cover common fastening points on most RC vehicles. However, depending on your specific model and how many fasteners you want to replace, you may need to order additional packs to outfit your entire vehicle.
- Can I reuse nyloc locknuts? — Whilst technically you can reuse nyloc locknuts multiple times, the nylon insert gradually wears down with each use. For best performance and reliability, Fastrax recommends replacing locknuts periodically, especially if you notice they're not holding bolts as securely as they once did. Having spare packs on hand ensures you're never left unable to maintain your RC vehicle properly.
