RC 4mm Anodized Light Blue Lock Nuts 10 Pack - 3RAC-N40/LB by 3Racing  [3RAC-N40/LB]

Secure, Anodized 4mm Lock Nuts for Hobby Builds

These light blue 4mm aluminum lock nuts are ideal for hobbyists who want secure fastenings with a clean appearance. The anodized surface helps protect the nuts from corrosion while keeping weight low.

Where to Use Them

Perfect for tightening components across many RC assemblies, these nuts are commonly used on body mounts, accessory brackets, and other standard fixtures that accept 4mm threads.

Why Pick Aluminum Fasteners?

Aluminum offers a good compromise between durability and weight savings. These lock nuts resist rust and are suitable for general-purpose use where a lighter fastener is preferred.
