NUT - JAM (Mitsubishi MB1037948)

MB1037948: A damaged jam nut can compromise the security of a threaded assembly, leading to loosening under vibration. This aftermarket replacement part references Mitsubishi catalog number MB1037948. The nut type is a jam nut, which is a thinner fastener used to lock a primary nut in place. Its plain mechanical function is to apply a clamping force against the primary nut to prevent rotation. A concrete generic failure consequence is that a loose jam nut can allow the primary fastener to back out, causing mechanical separation. Keeping a jam nut in sound condition helps maintain consistent tension in bolted joints. Verify the serial number or application, then call (562) 693-7748. The item ships at approximately 0.01 pounds.
