3Racing 3RAC-NF40/LB 4mm Light Blue Aluminium Flange Locknuts 10pcs  [3RAC-NF40/LB]

Secure flange fixings for precision RC builds

Model builders who favour tidy, reliable fittings will find the 3Racing 4mm aluminium flanged locknuts useful. The aluminium body keeps mass down while the flange spreads clamping force to reduce loosening under load. The light blue anodised finish also gives a neat appearance on exposed fittings.

Lightweight retention that looks the part

These flanged locknuts are made for hobbyists who want consistent performance without excess weight. The aluminium construction is kinder to unsprung mass and the flange helps prevent damage to softer mounting surfaces. Typical uses include securing wheels, pivot points and small suspension items.

Compatible across a range of models

These 4mm nuts fit many RC applications from street touring to off-road buggies. The 10 piece quantity provides spares for routine maintenance and upgrades. Always confirm thread match before tightening to avoid cross-threading.
