Jazrider M4-LNF-DB 4mm Blue Flanged Lock Nuts (4 Pcs) - durable blue finish  [M4-LNF-DB]

Keep fasteners tight with Jazrider 4mm flanged lock nuts

Keeping parts secured is essential for any RC project. The Jazrider 4mm flanged lock nuts in blue give reliable thread locking for a wide range of RC models, helping prevent loose hardware during spirited running.

Where these nuts work best

These 4mm flanged lock nuts suit both on-road and off-road builds, offering a broader contact area thanks to their flange. That helps spread clamping force and reduces the chance of damaging mounting surfaces under load.

Built for routine use and quick maintenance

Designed for everyday hobby use, the vibrant blue finish makes them easy to spot during maintenance. Fit them with a standard wrench for a snug, repeatable fastening that works for both experienced builders and those new to RC maintenance.
