The Jazrider M4-LNF-LB 4mm flanged lock nuts are engineered for hobbyist practicality. These four nuts combine a locking profile with a built-in flange to increase contact area and help maintain preload under vibration.
The flanged base reduces compressive stress on mounting surfaces and improves clamp distribution compared to a standard hex nut. This makes them suitable for repeated assembly and disassembly in typical RC maintenance cycles.
These M4 lock nuts are appropriate for use on servo horns, linkages, body fastenings and accessory mounts where a low-profile, secure nut is required. They are a straightforward upgrade to help reduce roadside loosening.
