AN924-5J - Nut

Part number AN924-5J is an aerospace-standard jam nut designed for locking and securing threaded fittings, bulkhead fittings, and bearing assemblies in aircraft hydraulic, fuel, pneumatic, and structural systems. The thin-profile hex design allows the nut to be tightened against another nut or fitting to prevent loosening and maintain positional adjustment under vibration and operational loads.

Manufactured from corrosion-resistant steel, the “J” suffix indicates a corrosion-resistant finish/material configuration suitable for aerospace service environments. The compact design makes it ideal for installations with limited clearance and applications requiring lightweight hardware.
