NUT - HEX JAM (Bobcat BC8D8)

BC8D8: A damaged hex jam nut can compromise the security of a threaded assembly. During inspection, a loose or worn jam nut may indicate that clamping force has been lost. Keeping a hex jam nut in sound condition helps maintain consistent tension on the fastener stack. This aftermarket replacement part references the Bobcat catalog and carries the part number BC8D8. The hex jam nut is a thin-profile nut used to lock another nut or bolt in place. A common failure consequence is that a degraded jam nut can allow the primary fastener to back out under vibration. Verify the serial number or application, then call (562) 693-7748.
