Jazrider M4-LNF-LB 4mm Flanged Lock Nuts - Light Blue, Pack of 4  [M4-LNF-LB]

Fasten with Confidence Using Jazrider M4-LNF-LB

These Jazrider M4-LNF-LB 4mm flanged lock nuts are aimed at model builders who want reliable, low-profile fastenings. The light blue finish helps you spot fittings quickly while the flange supports a firmer hold.

How the Flange Improves Stability

The flange increases contact area so the nut distributes load more evenly and is less likely to back off when exposed to vibration. That makes it a helpful upgrade for faster or rough-terrain models.

Versatile Use Across Models

Designed for common M4 thread sizes, these nuts are useful on chassis points, servo mounts, and accessory fittings. They are a straightforward way to improve reliability without changing major components.
