Whether you're racing a high-performance brushless RC truck or maintaining your favourite RC car, these replacement nuts are essential components that keep your vehicle running smoothly during intense action. Compatible with a wide range of Traxxas models including the Rustler Ultimate VXL, Slash Ultimate 4x4 VXL, Stampede 4X4 HD VXL, TRX-4 crawlers, and many more, these locking nuts provide the reliability and durability that competitive RC racing demands.

If you're investing in a ready to run RC model or building a custom setup, having quality replacement parts on hand is crucial for weekend bashing or track days. These 4mm flanged nylon locking nuts are manufactured to Traxxas standards and represent genuine OEM components that enthusiasts across the UK trust to keep their RC vehicles secure.

This pack contains eight individual nuts, giving you a complete set for all four wheels of your RC truck or buggy with spares for maintenance or replacement. Whether you're upgrading from worn fasteners, replacing damaged components, or simply stocking spare parts for your RC hobby, these Traxxas locking nuts represent excellent value and proven performance.

Key Features

• Serrated Flange Design — The serrated flange on each nut creates a locking grip that prevents vibration loosening during aggressive driving. This feature is particularly important for RC enthusiasts who engage in high-speed bashing or competition racing, where loose wheel fasteners can cause safety issues and performance degradation.
• Nylon Locking Mechanism — Each nut incorporates a nylon insert that creates friction when the bolt is installed, preventing the nut from backing off even under the intense vibration and stress of high-performance RC driving. This is more reliable than standard non-locking fasteners and reduces the need for frequent wheel maintenance checks.
• 4mm Thread Size — The 4mm thread diameter is the standard specification for wheel fasteners on most modern Traxxas vehicles, ensuring perfect fitment on your RC monster truck, short course truck, crawler, or other compatible models without modification.
• Steel Construction — These nuts are manufactured from hardened steel, providing superior strength and durability compared to aluminium alternatives. Steel fasteners resist stripping, maintain consistent clamping force over time, and withstand the repeated stress cycles that RC vehicles experience during regular use.
• Set of Eight Nuts — This pack provides a complete set of replacement nuts for both front and rear wheel assemblies, with two spare nuts for future maintenance or component replacement. Having extras on hand ensures you're never without essential fastening components during repair sessions or at the track.
• Genuine Traxxas Component — As an official Traxxas replacement part, these nuts are engineered to exact specifications and undergo quality control testing to ensure compatibility and performance with your Traxxas RC vehicle. Using genuine OEM parts guarantees reliability and maintains your vehicle's warranty eligibility.

Technical Performance

The Traxxas 4mm flanged nylon locking nuts represent a critical engineering solution to a common problem in RC vehicle maintenance. The combination of steel construction with a serrated flange and nylon locking insert creates a three-stage security system that addresses different failure modes. The serrated flange bites into the mounting surface, providing mechanical resistance to rotation. The nylon insert in the nut's bore creates a deformation fit that generates friction forces resisting loosening from vibration. Together, these design elements ensure that your wheels remain securely fastened through aggressive acceleration, deceleration, cornering, and the inevitable impacts encountered during RC bashing or competitive driving. The use of hardened steel rather than softer materials means these nuts maintain consistent clamping force across hundreds of fastening and unfastening cycles, which is essential for RC enthusiasts who regularly maintain their vehicles. The 4mm thread specification is precisely calibrated to match the wheel hubs on compatible Traxxas models including the Ford Fiesta ST Rally vehicles, Rustler series, Slash series, Stampede 4X4 models, and the full range of TRX-4 crawlers. This universal fitment across multiple vehicle platforms makes these nuts an economical choice for hobbyists with multiple RC cars in their collection.

Frequently Asked Questions

• Are these locking nuts suitable for all Traxxas RC vehicles? — No, these 4mm nuts are specifically designed for Traxxas models that use 4mm wheel fastener threads. Compatible vehicles include the Traxxas Rustler Ultimate VXL 4x4, Slash Ultimate 4x4 VXL, Slash HD XL-5, Stampede 4X4 HD VXL, TRX-4 series crawlers including the Chevrolet K10 Cheyenne, Ford F-150 Ranger XLT, Chevy K5 Blazer, Defender, and Nissan Pathfinder variants, as well as Ford Fiesta ST Rally models. Check your vehicle's manual or parts list to confirm the correct nut size before ordering.
• Why do RC vehicle wheels need locking nuts? — Standard nuts can gradually loosen under the intense vibration and stress of RC driving, potentially leading to loose wheels or complete wheel loss during use. Locking nuts with nylon inserts and serrated flanges resist this loosening through friction and mechanical grip, ensuring your wheels stay secure during high-speed runs, aggressive cornering, and impacts with obstacles. This is particularly important for serious RC racers and bashers who push their vehicles to the limit.
• How often should I replace these locking nuts? — Locking nuts typically maintain their security characteristics for hundreds of fastening cycles. You should replace them if you notice they no longer hold tight when reinstalled, if the nylon insert becomes damaged or compressed, or if the threads become stripped from over-tightening. Regular inspection during routine maintenance is recommended, especially if you're an active RC enthusiast who drives frequently.
• Will these nuts work with aftermarket wheels and hubs? — These nuts will fit any wheel hub with a standard 4mm thread, though compatibility depends on your specific aftermarket components. If you're upgrading to custom wheels or hubs, verify that your new parts use 4mm fastener threads. Some speciality RC components may use different thread sizes, so measurement is important before purchasing replacement fasteners.
• What is the difference between these serrated flange nuts and standard locking nuts? — These nuts feature a serrated flange on the underside that grips the mounting surface, providing mechanical resistance to rotation in addition to the nylon insert's friction-based locking action. This dual-mechanism approach makes them more reliable than basic nylon-insert nuts alone, especially for high-performance RC applications where vibration and stress are extreme.
