NUT - HEX JAM (Clark CL617865)

A damaged hex jam nut can compromise the security of a threaded fastener assembly. During inspection, a loose or worn jam nut may allow bolted connections to back off under vibration. Keeping a hex jam nut in sound condition helps maintain clamping force in mechanical joints. This aftermarket replacement part references Clark catalog number CL617865. The hex jam nut is a thin nut used to lock a primary nut in place by jamming against it. A common failure consequence is gradual loosening of the assembly, leading to rattling or misalignment. Verify the serial number or application, then call (562) 693-7748.
