Key Features

• Nyloc locking mechanism — The integrated nylon insert in these locknuts creates a self-locking feature that prevents fasteners from loosening under vibration, which is critical for RC vehicles that experience constant suspension movement, engine vibration, and impact forces during operation.
• M3 size specification — These nuts are precisely manufactured to M3 metric standard, making them compatible with a wide range of fastening points across numerous RC vehicle platforms, including drivetrain components, suspension assemblies, and body mounting points.
• Bright blue finish — The distinctive blue colour makes these nuts easy to identify and locate during assembly, disassembly, and maintenance work, reducing the time spent searching for fasteners and helping to organise your RC workshop or work bench.
• Pack of four units — Each pack contains four locknuts, providing enough fasteners for a typical suspension or drivetrain assembly, though experienced RC builders often keep several packs on hand for comprehensive vehicle builds or multiple model updates.
• Fastrax quality assurance — Manufactured by Fastrax, a trusted producer of RC spare parts and accessories, these locknuts undergo quality control processes to ensure reliable performance and longevity in demanding RC applications.

Technical Performance

The Fastrax M3 Blue Locknuts represent a critical component in RC vehicle assembly and maintenance. These are genuine locking nuts featuring a nylon insert that provides excellent vibration resistance without requiring additional threadlocker compounds or adhesives. The M3 metric thread size is one of the most commonly used fastener sizes in RC vehicles, appearing in suspension mounts, drivetrain assemblies, body posts, and various other connection points across different scales and types of RC cars. The blue anodised or plated finish provides both aesthetic appeal and corrosion resistance, ensuring the nuts maintain their appearance and functionality through multiple seasons of use. The nyloc design means that once these nuts are installed on a bolt or screw, they will remain securely in place even as your RC vehicle encounters rough terrain, jumps, collisions, and the constant micro-movements that occur during high-performance driving. This is far superior to standard non-locking nuts, which can gradually loosen and potentially cause mechanical failures during critical moments. The precision engineering ensures that the nuts will thread smoothly onto standard M3 fasteners without cross-threading or binding, making assembly quick and straightforward whether you're building your first RC car or maintaining a collection of competition vehicles.

Frequently Asked Questions

• What is a nyloc locknut and why do I need it for my RC car? — A nyloc locknut contains a nylon insert that creates friction on the bolt thread, preventing the nut from loosening due to vibration. RC vehicles experience significant vibration from motors, impacts, and suspension movement, so nyloc locknuts are essential to prevent fasteners from gradually loosening and causing mechanical failures during operation.
• Are these M3 locknuts compatible with my RC vehicle? — The M3 size is one of the most widely used fastener sizes in RC vehicles, and these locknuts are compatible with numerous platforms including Udi RC, FTX RC vehicles, and many other RC cars. Check your vehicle's assembly manual or consult with RC specialists to confirm M3 fasteners are correct for your specific model.
• How many locknuts do I need for a complete build? — This depends on your specific RC vehicle and which areas you're securing with locknuts. A typical suspension assembly might use 4-8 locknuts, so having several packs available is recommended. Many experienced builders maintain a stock of various sizes for maintenance and repairs.
• Can I use these blue locknuts multiple times? — Once a nyloc locknut has been installed and removed, the nylon insert may be damaged or worn, which reduces its locking effectiveness. It's best practice to replace locknuts with fresh ones rather than reusing them, ensuring maximum security for critical fastening points on your RC vehicle.
• What makes Fastrax parts reliable for RC use? — Fastrax has built a reputation in the RC hobby for producing quality spare parts and accessories that meet the demanding requirements of RC enthusiasts. Their components are engineered for durability and performance across various RC vehicle types and applications.
