NUT HEX JAM (CAT CT1050279)

A damaged hex jam nut can compromise threaded joint security in mechanical assemblies. This aftermarket replacement references CAT as the OE maker and cross-references part number CT1050279. The hex jam nut provides a thinner profile than standard hex nuts, allowing it to lock against another nut or serve in confined spaces. A loose or missing jam nut may allow vibration to loosen the primary fastener, leading to joint failure. Keeping a hex jam nut in sound condition helps maintain consistent clamping force on threaded connections. The item ships at approximately 0.039 pounds. Verify the serial number or application, then call (562) 693-7748.
