LOCKNUT - 5/16-18 (CAT CT302296)

A damaged locknut can allow threaded fasteners to loosen under vibration, leading to mechanical misalignment or component separation. During assembly, a locknut resists self-loosening through its built-in prevailing torque feature. Keeping a locknut in sound condition helps maintain clamping force in bolted joints. This aftermarket replacement part references the CAT catalog number CT302296. The part type is a locknut, a threaded fastener that secures bolts or studs by creating friction against the threads. A generic failure consequence is that a worn locknut may fail to hold torque, causing the joint to loosen over time. Verify the serial number or application, then call (562) 693-7748.
