WASHER - LOCK WITH TEETH (Yale YT0296360)

YT0296360: A damaged lock washer can allow threaded fasteners to loosen under vibration. The Yale catalog reference for this part is YT0296360. This aftermarket replacement part is a washer with internal teeth that bite into the mating surface. Its plain mechanical function is to resist rotational loosening of a nut or bolt. A concrete generic failure consequence is that a missing or worn lock washer may lead to fastener back-out and joint separation. Keeping a lock washer in sound condition helps maintain clamp load in bolted assemblies. Verify the serial number or application, then call (562) 693-7748.
