LOCK WASHER - SPLIT 1/2 INCH (CAT CT29P27C7)

A damaged lock washer can allow threaded fasteners to loosen under vibration, leading to joint failure. The split design creates spring tension that resists rotational loosening in bolted connections. This aftermarket replacement part references CAT as the OE maker and carries the cross-reference number CT29P27C7. The specified size is 1/2 INCH, which matches the catalog listing for this hardware washer type. During assembly, the split edges bite into the mating surfaces to maintain clamping force. A common failure consequence is a fastener backing out, which can cause component separation or misalignment. Verify the serial number or application, then call (562) 693-7748.
