LOCK NUT - NYLON INSERT (CAT CT1050286)

A damaged lock nut with a nylon insert can lead to fastener loosening under vibration. This aftermarket replacement part references the CAT catalog and carries the cross-reference number CT1050286. The nylon insert provides prevailing torque by deforming against the threads, resisting self-loosening. A common failure consequence is gradual joint separation, which may cause component misalignment or noise. During routine service, a lock nut that spins freely on the threads indicates the insert has worn out. This item ships at approximately 0.124 POUNDS. Verify the serial number or application, then call (562) 693-7748.
