Key Features

• M3 Threaded Size — These locknuts are precisely machined to M3 specifications, making them compatible with M3 fastening points across a wide variety of RC applications and aftermarket upgrades, ensuring perfect fitment.
• Flanged Design — The integrated flange provides an expanded bearing surface that distributes clamping force across a larger area, preventing the nut from sinking into softer materials and providing superior holding strength compared to standard locknuts.
• Locking Mechanism — Built-in locking features ensure these nuts stay securely fastened even under the constant vibration and stress experienced during RC driving, eliminating the need for separate threadlocker compounds in many applications.
• Black Colour Finish — The professional black coating not only provides a clean, finished appearance to your RC build but also offers a degree of corrosion resistance to protect the fasteners during use.
• Pack of Four — You receive four individual locknuts per pack, providing multiple fastening points for comprehensive upgrades or repairs across different areas of your RC model.
• Genuine Fastrax Manufacturing — These are authentic components manufactured by Fastrax, a trusted name in RC hobby hardware, guaranteeing quality and reliability that matches the performance expectations of serious RC enthusiasts.

Technical Performance

The Fastrax M3 Black Flanged Locknuts represent precision engineering tailored for the demands of RC vehicles. The M3 metric thread specification is carefully manufactured to international standards, ensuring compatibility with genuine M3 fastening points and aftermarket components designed for this size. The flanged construction is engineered to provide superior load distribution, which is particularly important in RC applications where vibration and shock loads are constant factors. The locking mechanism integrated into the nut's design works by creating friction between the nut and the bolt thread, preventing self-loosening caused by vibration—a critical consideration for RC car owners who want to avoid losing components during high-speed driving or off-road use. The black finish applied to these locknuts is not merely cosmetic; it provides protection against oxidation and environmental exposure, maintaining the integrity and appearance of your RC model over extended periods of use. Whether you're working on a crawler tackling challenging terrain, a buggy on the track, or any other RC vehicle type, these locknuts deliver the fastening security required for reliable performance. The pack of four provides versatility for multiple fastening applications, allowing you to address several points on your RC build simultaneously.

Frequently Asked Questions

• What is the difference between flanged locknuts and standard locknuts for RC cars? — Flanged locknuts feature an expanded circular base that sits underneath the nut itself. This flange distributes clamping force across a larger surface area, preventing the nut from digging into softer materials and providing superior holding strength. This makes them particularly valuable for RC applications where materials vary and vibration is constant.
• Are these locknuts suitable for beginners working on RC models? — Yes, absolutely. These Fastrax M3 Black Flanged Locknuts are excellent for RC enthusiasts of all experience levels. Whether you're learning how to maintain your first RC car or building a high-performance setup, these reliable fasteners are essential hardware that any RC hobbyist should have in their spares kit. They're particularly useful when replacing worn fasteners or upgrading components.
• What RC models can use M3 locknuts? — M3 locknuts are compatible with a wide range of RC models, particularly those fitted with M3 fastening points. This includes many aftermarket upgrade kits, optional parts, and specific components designed for popular RC vehicles across different scales. Check your RC model's parts diagram or upgrade specifications to confirm M3 compatibility for your particular vehicle.
• Why should I use locknuts instead of regular nuts on my RC vehicle? — The integrated locking mechanism in these locknuts creates friction that prevents self-loosening caused by vibration and shock loads—exactly what your RC car experiences during driving. Using locknuts reduces the risk of nuts gradually unscrewing during operation, which could result in lost components or mechanical failure. This makes them a superior choice for RC applications where reliability is essential.
• Do these locknuts require threadlocker compound? — The built-in locking mechanism typically provides sufficient security without additional threadlocker compound, though some users choose to apply threadlocker for extra assurance on critical fastening points. The locking feature means you have the option to use these nuts without additional products, saving time during assembly and maintenance.
• Can I reuse these locknuts multiple times? — Yes, flanged locknuts can generally be reused several times. However, each time a nut is removed and reinstalled, the internal locking feature experiences some wear. If you notice a nut becoming loose or its holding strength diminishing after several applications, it's advisable to replace it with a fresh unit from a new pack.
