Secure fastening for hobby builds

RC builders looking for a reliable fastener will find the 3Racing 4mm Aluminium Serrated Locknuts an easy upgrade. Produced from quality aluminium, these locknuts balance light weight with solid holding power for a secure connection on 4mm fittings. The serrated profile helps lock the nut against loosening while running.

Main advantages

Material: Aluminium for a lightweight yet sturdy fastener
Design: Serrated edge to keep the nut in place
Color: Matte black for a discreet finish
Compatibility: Suitable for many models that use 4mm nuts

When to fit these locknuts

These locknuts are a sensible choice for everyday RC use, whether trimming laps or practising off road. They reduce routine checks and let you concentrate on setup and handling.

How tight should I install these locknuts?

Tighten until the serration bites the surface and the joint feels firm, but do not overtighten as this can damage threads or components.

Will the black finish chip easily?

The black finish is robust for normal use, though heavy impacts may mark the surface. Function is not affected by cosmetic wear.

Are these reusable after removal?

You can reuse them in most cases, but inspect serrations and threads for wear before refitting to critical joints.
