WASHER - LOCK (CAT CT2Y-6141)

A damaged lock washer can lead to fastener loosening under vibration. During assembly, a lock washer resists rotational loosening by embedding into the mating surface. The aftermarket replacement part references CAT as the OE maker and cross-references part number CT2Y-6141. This hardware washer type provides a plain mechanical function of increasing friction between the fastener head and the joint. A common generic failure consequence is that a missing or worn lock washer allows the nut or bolt to back off over time. Keeping a lock washer in sound condition helps maintain clamp load in bolted connections. Verify the serial number or application, then call (562) 693-7748.
