NUT - JAM (Nissan NI89-11340)

A damaged jam nut can compromise the security of a threaded fastener assembly. During inspection, a jam nut may show signs of loosening or thread wear. Keeping a jam nut in sound condition helps maintain consistent clamping force on the mating component. This aftermarket replacement part references Nissan as the OE maker and carries the cross-reference part number NI89-11340. The jam nut functions as a secondary nut that locks a primary nut in place by applying friction to the threads. A common failure consequence is that a loose jam nut allows the primary fastener to back out under vibration. Verify the serial number or application, then call (562) 693-7748.
