Racing Focused Fastener Security

The 3Racing 3RAC-NS40/PK serrated locknuts are intended for tuners who require repeatable clamp force in competition environments. The serrated interface increases friction at the mating surface to resist rotational creep under vibration.

Performance Oriented Construction

Manufactured from lightweight anodised aluminium, these locknuts balance minimal mass with robust locking action. Their finish improves corrosion resistance while keeping unsprung or rotating mass to a minimum.

Application and Setup Notes

Use these locknuts on suspension linkages, wheel fittings and other service items where secure torque retention is critical. For best results, verify thread compatibility and perform initial torque checks followed by a short break-in run to confirm stability.

How do serrated locknuts affect setup tuning?

Serrations increase friction at joints which can stabilise geometry by preventing incremental rotation of attachment points. They should be used where a fixed relationship is required between components.

Any installation precautions for race use?

Confirm thread fit and torque consistently across all identical points. After initial fitting, run a short test session and recheck torque to ensure no settling occurs under load.

Should they be combined with other locking methods?

In high duty applications, serrated locknuts provide good retention alone, but in extreme environments pairing with thread locker or locking washers can add redundancy depending on rules and track conditions.
