Protect your build with Jazrider 4mm flanged lock nuts

Loose fasteners are a common cause of on-track issues. The Jazrider 4mm flanged lock nuts in blue provide a straightforward locking option to keep components secure across a range of RC vehicles.

Suitable uses and fitment

These lock nuts are suitable for both competition and casual builds. The flange reduces point loading on parts, which is helpful on plastic or thin metal mounting surfaces during hard use.

Service friendly and visible

The blue colour makes them easy to find during teardown and repairs. They fit easily with ordinary spanners and are a practical upgrade for hobbyists who want reliable hardware without fuss.
