The MS21042L04 is an all-metal self-locking hex nut with an integral extended washer (style H) conforming to NASM21042 specifications. The extended washer distributes bearing load across mating surfaces while the self-locking feature resists vibration-induced loosening in aerospace assemblies. Commonly used in airframe panel attachments and structural connections where a separate washer would be impractical.
The prevailing-torque design maintains clamp load without deforming threads. Installation requires verification of thread compatibility and proper torque application per applicable maintenance manuals.
