For racers and tuners needing controlled hardware behaviour, the 3Racing 4mm Serrated Aluminium Locknuts provide predictable retention without adding unnecessary mass. Manufactured to suit standard 4mm interfaces, these nuts help maintain clamped joints through aggressive driving and repeated setup changes. The serrated face increases friction at the contact surface to reduce unwanted rotation under repeated shock loading.
Use these locknuts on steering and suspension linkages where consistent clamping force is important for predictable handling. They are a simple, effective choice for setup work and quick component swaps during race day maintenance.
