WASHER - SPLIT LOCK 1/4 (Yale YT18425)

A damaged split lock washer can compromise fastener tension, leading to loosening under vibration. During assembly, this washer type resists rotational loosening by embedding its split edges into the mating surfaces. The catalog reference is Yale part number YT18425, an aftermarket replacement part. Keeping a split lock washer in sound condition helps maintain consistent clamping force in bolted joints. A common failure consequence is gradual fastener back-out, which may allow components to separate. This washer is a 1/4-inch split lock type, serving the general function of preventing nut or bolt rotation. Verify the serial number or application, then call (562) 693-7748.
