NUT - JAM (Mitsubishi MB0000-10010)

MB0000-10010: A jam nut that has loosened can allow threaded connections to back off under vibration. This aftermarket replacement part references Mitsubishi catalog number MB0000-10010. The nut type is a jam nut, which is a thin hex nut used to lock another nut in place by jamming against it. A common failure consequence is that a loose jam nut permits gradual loosening of the primary fastener, leading to joint separation. During routine service, a jam nut may be found cracked or stripped from overtightening. Keeping a jam nut in sound condition helps maintain clamp load on bolted assemblies. Verify the serial number or application, then call (562) 693-7748.
