3Racing 3RAC-NF40/SI Race Oriented 4mm Flanged Nuts

The 3Racing 4mm Aluminium Flanged Lock Nuts in silver are aimed at hobbyists focused on setup and performance. Their aluminium build reduces rotating and unsprung mass while providing repeatable fastening for quick setup changes and part swaps.

Consistent Fit for Setup Work

The flange gives a stable seating surface that helps maintain alignment under vibration and high cornering loads. Use these nuts where consistent clamp and minimal added weight are priorities during tuning and race preparation.

Workshop and Track Benefits

  • Suitable for precision setup and component changes
  • Lightweight aluminium assists overall vehicle balance
  • Flanged profile secures parts and resists backing off
  • Practical for both practice sessions and race day maintenance

Should I change wheel balance when switching to aluminium nuts?

Aluminium nuts reduce rotational weight slightly; if you are doing precise wheel balancing for competition, note the change and recheck balance after switching hardware.

Do these nuts help with quicker pit stops?

Their light weight and consistent seating aid fast, repeatable wheel and component changes, especially when using the correct driver and torque practice.

Any special advice for race teams?

Keep a set of matched spares and avoid over torque to protect aluminium threads; inspect after heavy use and replace if signs of wear appear.
