Sturdy and Distinctive 3RACING 3RAC-N40/PU Lock Nuts

Choosing the right small hardware matters for long term reliability. These 3RACING 4mm purple aluminum lock nuts give a secure fastening solution while adding a clear visual cue for parts identification during service.

Fitment and Use Cases

The 4mm thread size is suitable for many common RC linkages and mount points, helping keep components tight through hard runs. Use these lock nuts when rebuilding suspension mounts, replacing wheel hardware, or when doing routine maintenance to reduce loosening under vibration.

Durability and Colour Notes

Made from aluminum, these lock nuts resist typical wear from regular hobby use and are light on weight. The purple finish helps you quickly spot matched hardware and makes kit builds easier to organise.
