Race-Ready 3Racing 3RAC-NF40/PU Fasteners

Engineered for racers who demand repeatable hardware performance, the 3Racing 4mm Aluminum Flanged Lock Nuts provide a low mass, secure fastening solution. The aluminium material reduces rotating and unsprung weight while the flanged geometry ensures broader load distribution on mounting surfaces, minimising loosening during aggressive driving.

Tuning and Setup Benefits

The flange helps maintain clamping across suspension and steering joints, aiding consistent handling lap after lap. The purple finish offers quick visual confirmation of component changes in the pits, speeding setup checks between heats.

Compatibility and Maintenance

These 4mm nuts are compatible with standard RC threads and are suitable for competitive club racing where weight and serviceability matter. Regular inspection and correct torque application will preserve thread life and maintain reliable performance.

Are these nuts suitable for high vibration race conditions?

The flanged design increases resistance to self-loosening under vibration, making them appropriate for many race environments; for extreme conditions, pair with threadlocker or use periodic re-torque checks.

Do they affect wheel balance or rotational mass?

Aluminium nuts reduce rotational mass compared with steel equivalents, offering a small advantage in throttle response and overall balance when used across multiple wheel fittings.

Recommended service interval for racing use?

Inspect fasteners before each race day and re-torque critical items after the first run; replace any nuts that show thread wear or flange deformation.
