3Racing 3RAC-NF40/LB Light Blue 4mm Flanged Locknuts 10 Pack  [3RAC-NF40/LB]

Practical flanged locknuts for everyday RC use

For hobbyists needing a dependable, low weight nut, the 3Racing 4mm flanged aluminium locknuts are a sensible option. The flange increases the seating area, reducing the chance of loosening during rough running while the aluminium body helps keep overall weight down.

Durable, lightweight fastening for common mounts

These locknuts suit a range of fastening points where reduced mass and a clean finish matter. The light blue anodised surface adds a neat visual touch while the aluminium core lowers unsprung weight compared with heavier metals. Typical applications include wheel hubs, shock mounts and linkage points.

Ready for upgrades and maintenance

The 4mm size fits many standard RC threads and comes in a 10 piece pack to cover multiple uses or spares for maintenance. As with all fasteners, check thread engagement and seating before final runs to avoid damage.
