NUT - JAM 1/4-28 (Bobcat BC8D-4)

BC8D-4: A damaged jam nut can compromise the security of a threaded assembly. During inspection, a loose or missing jam nut may allow fastened components to shift or vibrate. The jam nut's primary function is to lock another nut or bolt in place by applying friction against the threads. This aftermarket replacement part references the Bobcat catalog number BC8D-4. It is a 1/4-28 thread size nut, commonly used to prevent loosening under dynamic loads. A common failure consequence is that a jam nut that strips or backs off can lead to fastener failure and component separation. Verify the serial number or application, then call (562) 693-7748.
