NUT - JAM (CAT CT20210010)

A jam nut that seizes against another nut to prevent loosening under vibration is a common hardware component. The catalog reference for this aftermarket replacement part is CAT CT20210010. Its plain mechanical function is to lock a fastener assembly by jamming against a primary nut. A generic failure consequence of a worn jam nut is that the primary fastener can back out, leading to component separation. Keeping a jam nut in sound condition helps maintain secure bolted joints in various assemblies. Verify the serial number or application, then call (562) 693-7748. This part is an aftermarket replacement sourced from the CAT catalog.
