NUT - JAM (Komatsu KO01501-00805)

KO01501-00805: A damaged jam nut can compromise the security of a threaded assembly, leading to loosening under vibration. During inspection, a jam nut may show signs of thread wear or deformation that reduce its locking ability. This aftermarket replacement part references the Komatsu catalog and carries the cross-reference number KO01501-00805. The jam nut is a thin fastener used to lock another nut or bolt in place by creating friction between threads. A common failure consequence is gradual loosening of the primary fastener, which can cause component misalignment or detachment. Keeping a jam nut in sound condition helps maintain consistent clamping force in static or low-vibration applications. Verify the serial number or application, then call (562) 693-7748.
