NUT - JAM (Mitsubishi MB000034016)

MB000034016: 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 reduces its locking ability. This aftermarket replacement part references the Mitsubishi catalog number MB000034016. The jam nut functions as a thin fastener that locks a primary nut in place by applying friction. A common failure consequence is that a loose jam nut allows the primary fastener to back off, causing mechanical play or separation. Keeping a jam nut in sound condition helps maintain consistent clamping force in bolted joints. Verify the serial number or application, then call (562) 693-7748.
