Technical Fastening Notes for 3RACING 3RAC-NS40/SI

These serrated aluminium locknuts are aimed at racers who need predictable clamp and repeatable hardware behaviour. The serrations create localized surface bite that increases friction without altering thread engagement geometry, helping maintain preload on linkages and mounts in dynamic conditions.

Performance Characteristics

The serrated face resists micro-rotation from vibration, preserving assembly tension during high rpm and rough track use. For competitive setups, they provide a reliable method to reduce time spent checking fasteners between runs.

Application and Maintenance

Use these locknuts where metal-to-metal contact is present for optimal serration performance. Inspect serration edges and mating surfaces periodically; replace if serrations are deformed or if threads show galling to retain consistent clamping force.

What is the recommended use case for these locknuts in a race setup?

Fit them on suspension and steering attachment points where vibration and shock loads can cause conventional nuts to loosen, to keep setup geometry steady.

Can these be used with assembly lubricants or anti-seize?

Avoid heavy lubricants on the serrated face as they can reduce grip; light anti-seize on threads is acceptable if corrosion prevention is needed.

Are these locknuts suitable for precision suspension tuning?

Yes, they help maintain component position between runs, which supports repeatable suspension settings and consistent handling.
