Overview

The Fastrax M4 Aluminium Flanged Locknuts in striking blue are essential upgrade parts for RC enthusiasts looking to enhance both the performance and appearance of their vehicles.

These flanged locknuts are specifically engineered to prevent fasteners from loosening during intense off-road action, making them an indispensable upgrade for any RC model enthusiast.

The pack contains four locknuts, providing enough parts for a complete set of wheels on most RC vehicles or spare upgrades for your spares box.

Key Features

• M4 Size with Flanged Design — The flanged construction features a wider bearing surface that protects wheel rims and distributes clamping force more evenly than conventional nuts, preventing cosmetic damage and ensuring wheels stay perfectly aligned during aggressive driving.
• Locking Nut Technology — These are genuine locking nuts that resist vibration-induced loosening, which is critical when you're pushing your RC buggy or truck hard across challenging terrain or high-speed drift courses where normal fasteners would work themselves loose.
• Aluminium Construction — Lightweight aluminium material reduces unsprung weight on your RC model, contributing to better handling characteristics and improved suspension response, whilst maintaining exceptional strength and durability for competitive use.
• Eye-Catching Blue Colour — The vibrant blue finish matches perfectly with blue RC truck bodywork, blue RC buggy shells, and blue-themed custom builds, giving your model a polished, professional appearance that looks as good as it performs.
• Pack of Four — Each pack contains exactly four locknuts, providing a complete set for all four wheels of your RC vehicle, or allowing you to keep spares on hand for maintenance and repairs.
• Universal RC Compatibility — Designed to work with a wide range of RC platforms including FTX Apache 2.0 RC trucks, FTX Banzai drift cars, FTX Bugsta RC buggies, FTX Carnage models, FTX Crossbow RC truggy trucks, FTX Vantage RC buggies, and FTX Zorro trophy trucks, plus many other brands using M4 fastener systems.

Technical Performance

These M4 Fastrax Aluminium Flanged Locknuts represent a significant upgrade over standard hardware found in ready-to-run RC vehicles. The combination of aluminium construction with a flanged locking design creates a fastening system that performs under the demanding conditions faced by modern RC models. The flanged design is particularly important for protecting expensive wheels and rims from the pressure marks and damage that can be caused by conventional hex nuts, ensuring your investment in quality wheel sets remains protected. Users consistently report that these locknuts are easier to fit than serrated washers and standard nuts, whilst providing superior performance and a more refined appearance. The locking mechanism ensures fasteners remain secure during acceleration, braking, and cornering forces experienced during both casual bashing sessions and competitive RC racing. Available in multiple colours including this striking blue option, these nuts allow you to customise your RC buggy, truck, or drift car to match your chosen colour scheme, creating a fully coordinated and professional-looking setup. The M4 sizing makes these compatible with a vast range of RC platforms from various manufacturers, making them a universal solution for upgrading your RC car UK collection.

Frequently Asked Questions

• Are these Fastrax M4 locknuts compatible with my FTX RC truck? — Yes, Fastrax M4 Aluminium Flanged Locknuts are specifically compatible with numerous FTX models including the Apache 2.0 Trophy Truck (both red and blue variants), Banzai drift car, Bugsta buggy, Carnage 2.0 trucks (brushed and brushless), Carnage NT nitro truck, Crossbow brushless truggy, Vantage 2.0 buggy, and Zorro Trophy Truck. If you own an FTX RC vehicle, these are an excellent upgrade choice.
• What makes flanged locknuts better than standard nuts for RC cars? — Flanged locknuts feature a wider base that distributes clamping pressure more evenly across a larger surface area. This wider bearing surface protects your wheel rims from the indentation marks and cosmetic damage that standard hex nuts can cause. Additionally, the locking mechanism prevents vibration from loosening fasteners during driving, which is essential for maintaining vehicle safety and performance during intense RC bashing or racing sessions.
• Can I use these on any RC model, or are they specific to certain brands? — These M4 locknuts are universal fasteners compatible with any RC vehicle, RC buggy, RC truck, or RC drift car that uses M4 threaded studs or axles. Whether you're running Traxxas, ARRMA, Losi, FTX, or other RC brands, if your model accepts M4 fasteners, these Fastrax locknuts will work perfectly.
• How many do I need for my RC vehicle? — A standard four-wheel RC model requires four locknuts for the wheel studs (one per wheel). This pack contains exactly four, providing a complete set. If you want spares or are upgrading multiple vehicles, consider ordering additional packs.
• Are these suitable for competitive RC racing as well as casual bashing? — Absolutely. These locking nuts are trusted by both weekend RC enthusiasts and serious competition racers. The secure locking mechanism is particularly important during racing where fasteners face continuous vibration and high lateral forces during cornering, acceleration, and braking.
• What is the difference between these and the serrated washers and nuts that came with my RC truck? — The flanged design on these Fastrax locknuts provides a much larger bearing surface than traditional serrated washers and standard nuts. This protects your wheel rims from damage and provides better weight distribution. The locking mechanism also provides superior vibration resistance compared to serrated washers, which can gradually work loose over time. Users report that these nuts are gentler on wheels whilst providing superior security.
