Axial AXIC3150 Serrated Locknut M4 Black

This Axial Serrated Nylon Lock Nut set includes 10 black M4 flanged locknuts with a serrated face that bites into the mounting surface, commonly used as wheel or servo saver nuts across several Axial RC platforms including the RR10 Bomber and Wraith Spawn. The nylon insert resists loosening from vibration.

Because it's a genuine Axial fastener built to the standard M4 serrated flange locknut specification, it's a direct-fit replacement anywhere this size is called for in your build's hardware list, without requiring any substitution.

This is a general hardware replacement item rather than a model-specific part, useful for any Axial build using this locknut size. The set includes 10 locknuts per package.
