WASHER - LOCK - 5/16 STEEL (Yale YT220075475)

YT220075475: A damaged lock washer can allow threaded fasteners to loosen under vibration, leading to mechanical misalignment or component separation. During assembly, a lock washer's split or toothed design resists rotation by biting into the mating surfaces. The aftermarket replacement part cross-references Yale part number YT220075475 and is a 5/16 steel lock washer. Its general function is to prevent nuts and bolts from backing off due to dynamic loads. A common failure consequence is that a worn or missing lock washer may cause a fastener to loosen, resulting in rattling or eventual part detachment. Keeping a lock washer in sound condition helps maintain clamping force in bolted joints. Verify the serial number or application, then call (562) 693-7748. This item ships at approximately 0.004 pounds.
