Overview

The Traxxas 5mm Red Aluminium Serrated Lock Nuts (TRX8447R) are precision-engineered fastening components designed to keep your RC car's wheels securely in place during intense driving sessions. Whether you're a competitive racer pushing your RC buggy to its limits, a weekend basher enjoying off-road thrills with your RC monster truck, or an RC enthusiast in the UK looking to upgrade and maintain your vehicle, these locking nuts deliver the reliability and aesthetic appeal that Traxxas is renowned for. Sold as a set of four, these nuts are an essential spare part for any serious RC vehicle owner who demands performance and durability.

Lightweight yet incredibly strong, these 5mm anodised aluminium flanged lock nuts represent the perfect balance between form and function. The vibrant red anodised finish doesn't just look great on your RC car—it's a protective coating that guards against corrosion and wear. The serrated flange design combined with the nylon locking washer ensures your wheels stay firmly secured even when you're pushing your RC truck or buggy to its absolute limits on the track or off-road terrain. This is why Traxxas lock nuts are trusted by RC enthusiasts across the UK and beyond.

If you're running a Traxxas Maxx Slash, UDR Unlimited Desert Racer, or WideMaxx Monster Truck, you already understand the importance of quality components. These 5mm flanged nylon locking nuts are compatible with a wide range of current Traxxas models and represent the factory-approved solution for wheel fastening. Whether you need replacements after wear and tear or you're building a competition-grade setup, these nuts deliver the security and performance your RC vehicle demands.

Key Features

• Lightweight Aluminium Construction — Made from precision-machined aluminium, these nuts reduce rotational mass at the wheels, which directly improves your RC car's handling, acceleration and overall responsiveness, particularly important when competing or pushing your vehicle hard.
• Red Anodised Finish — The vibrant red anodised coating provides a protective barrier against corrosion, oxidation and damage from dirt, water and UV exposure, ensuring your RC vehicle looks fresh and your nuts maintain their structural integrity over extended use.
• Serrated Flanged Design — The serrated flange grips firmly against the wheel surface, preventing loosening caused by vibration and impacts during aggressive driving, jumps and rough terrain on UK off-road tracks.
• Nylon Locking Washer — An integrated nylon locking element provides a secure grip that resists vibration-induced loosening, meaning your wheels stay put during even the most intense action, whether you're racing or bashing.
• M5 Thread Size — The 5mm thread size is the standard fastening specification for Traxxas performance vehicles, ensuring perfect compatibility with your RC truck, buggy or monster truck's wheel hubs.
• Set of Four — Comes as a complete set of four nuts, providing fasteners for all four wheels of your RC vehicle, or serving as quality spares to keep on hand for maintenance and repairs.
• Factory Traxxas Quality — These are genuine Traxxas OEM parts, manufactured to exacting standards and used as original equipment on current Traxxas models, guaranteeing reliability and fitment.

Technical Performance

These 5mm flanged nylon locking nuts represent Traxxas's commitment to precision engineering and quality control. Machined from high-grade aluminium and finished with a protective red anodised coating, they deliver the strength-to-weight ratio critical for high-performance RC vehicles. The serrated flange design creates a mechanical lock that prevents loosening through micro-movements and vibration, while the integrated nylon washer provides additional security through friction-based locking. This dual-lock system is engineered to withstand the extreme forces experienced during cornering, acceleration, braking and impacts on RC racing tracks and off-road terrain throughout the UK. The M5 thread specification is precision-manufactured to exacting tolerances, ensuring smooth installation and removal without stripping or damage. Whether you're upgrading your RC short course truck, monster truck, or unlimited desert racer, these nuts deliver OEM-level performance and reliability that keeps your wheels secure throughout extended driving sessions.

Frequently Asked Questions

• Are these genuine Traxxas lock nuts suitable for my RC vehicle? — Yes, these TRX8447R nuts are genuine OEM Traxxas components. They're compatible with a wide range of current Traxxas models including the Maxx Slash 1/8 4WD 6S Brushless Short Course Truck (all colour variants), the UDR Unlimited Desert Racer Pro-Scale 4WD RTR Short Course Truck, and the WideMaxx Monster Truck (all colour variants). Check your vehicle's documentation to confirm M5 thread compatibility.
• Why do my wheel nuts keep loosening during driving? — Standard nuts can work loose due to vibration and the rotational forces experienced during RC driving. The serrated flange and nylon locking washer in these Traxxas lock nuts create a mechanical lock that resists loosening far better than basic fasteners, keeping your wheels secure through intense action on track or off-road.
• What's the difference between these serrated lock nuts and standard wheel nuts? — These nuts feature a serrated flange that grips the wheel surface to prevent rotation, plus an integrated nylon locking washer that provides friction-based security. This dual-lock system is more effective at resisting vibration-induced loosening than standard nuts, making them ideal for high-performance RC vehicles.
• Do I need any special tools to install these nuts? — You'll need a 5mm hex wrench or the appropriate nut driver that fits your vehicle's wheel hubs. Installation is straightforward—simply remove your old nuts and thread these replacements on until snug. Do not over-tighten, as this can damage the nylon locking element.
• How often should I replace my lock nuts? — The nylon locking element gradually wears with each installation and removal cycle. If you notice wheels becoming loose more easily or if the nylon appears worn, it's time to replace them. Keeping spare sets on hand is wise for competitive racers and frequent bashers.
• Can I use these on other RC vehicles besides Traxxas models? — These are M5-threaded nuts, so they'll work on any RC vehicle with M5 wheel studs or threaded hubs. However, they're optimised for Traxxas vehicles and we recommend checking compatibility with non-Traxxas models before purchase.
• Why choose aluminium nuts instead of steel? — Aluminium offers a superior strength-to-weight ratio, reducing unsprung mass at the wheels which improves handling and acceleration. The red anodised coating provides excellent corrosion resistance while maintaining that lightweight advantage over heavier steel alternatives.
