Precision Gold Serrated Locknuts for RC Wheels

Choose 3Racing 3RAC-NS40/GO 4mm aluminium serrated locknuts to ensure secure wheel attachment during strong acceleration and hard braking. The serrated face locks to the wheel surface to help prevent gradual loosening while the anodised gold coating resists wear from track use.

Why Serrations Improve Security

Serrations create a higher friction interface against the wheel, helping to hold clamping force under vibration and shock. This makes them suitable for sprint racing and demanding practise sessions.

General Fitment Notes

These 4mm locknuts are designed for broad compatibility with most 1/10 scale models. They are an easy maintenance upgrade to replace worn or plain nuts for better long term wheel security.

Can I use these on alloy wheel faces without marking them?

The serrations may leave minor contact marks on soft or polished wheel faces; test on a spare wheel if finish preservation is important.

How often should I check the nuts during race day?

Check wheel tightness before each heat and after crash repairs; the serrations reduce back-off but routine checks are still recommended.

Are these a direct upgrade from plastic nuts?

Yes, aluminium serrated locknuts provide a stronger, lighter alternative to plastic nuts and are a common upgrade for durability and consistency.
