LOCKNUT (CAT CT0050473)

CT0050473: A damaged locknut can compromise the security of a bolted joint, leading to loosening under vibration. During inspection, a locknut may show signs of thread wear or deformation that reduces its clamping force. This aftermarket replacement part references the CAT catalog number CT0050473. The locknut type uses a prevailing-torque feature to resist self-loosening. A common failure consequence is gradual fastener loosening, which can cause component misalignment or noise. Keeping a locknut in sound condition helps maintain consistent preload in threaded assemblies. Verify the serial number or application, then call (562) 693-7748.
