WASHER - LOCK (CAT CT2H-3923)

A damaged lock washer can lead to fastener loosening under vibration. During assembly, a lock washer resists rotational loosening by creating tension between the nut and the mating surface. This aftermarket replacement part references CAT as the OE maker and carries the cross-reference part number CT2H-3923. The washer type provides a plain mechanical function of preventing hardware from backing out due to dynamic loads. A common generic failure consequence is that a missing or worn lock washer allows bolts to loosen, causing component misalignment or detachment. Keeping a lock washer in sound condition helps maintain joint integrity in fastened assemblies. Verify the serial number or application, then call (562) 693-7748.
