Setup focused locknut performance

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.

Technical highlights

  • Material: Aluminium for low mass and adequate strength in competitive applications
  • Design: Serrated contact surface to improve holding power in tuned setups
  • Color: Black finish that minimises reflection and blends with race hardware
  • Compatibility: Intended for assemblies accepting 4mm nuts commonly found in racing components

Application notes

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.

Yes, aluminium serrated locknuts are durable for multiple teardown cycles provided threads and serrations are inspected and not damaged during removal.
Their secure grip helps keep adjustments in place, making them useful when frequent fine tuning is required during setup sessions.
For endurance or extreme vibration conditions, a medium strength threadlocker can complement the serrations. For quick serviceability during races, rely on the serration alone unless extra security is necessary.
Clean mating surfaces before installation and torque to a consistent setting so handling changes are predictable between runs.
