LOCKNUT - NYLON (CAT CT2I2984)

A damaged locknut can allow threaded fasteners to loosen under vibration, leading to component separation. This aftermarket replacement part references the CAT catalog and carries the cross-reference number CT2I2984. The locknut type uses a nylon insert to create friction against the bolt threads, resisting self-loosening. A common failure consequence is that a worn or stripped locknut fails to maintain clamping force, risking joint failure. Keeping a locknut in sound condition helps secure bolted connections in mechanical assemblies. The part is a nylon-insert locknut, a hardware nut category item. Verify the serial number or application, then call (562) 693-7748.
