NUT(L)-JAM (CAT CT20222000)

CT20222000: A jam nut that has loosened can allow threaded connections to back off under vibration. This aftermarket replacement part references CAT as the OE maker and cross-references part number CT20222000. The nut type is a jam nut, which is a thinner nut used to lock a primary nut in place. Its plain mechanical function is to apply clamping force against the primary nut to prevent rotation. A common failure consequence is that a loose jam nut leads to fastener loosening and potential component separation. Keeping a jam nut properly torqued helps maintain joint integrity in threaded assemblies. Verify the serial number or application, then call (562) 693-7748.
