WASHER (Yale YT215990)

YT215990: A worn washer can compromise the clamping force of a bolted joint, leading to loosening over time. The Yale catalog reference YT215990 identifies this as an aftermarket replacement part. This hardware washer provides a bearing surface for a fastener and distributes load evenly. A missing or degraded washer may allow a nut or bolt to embed into the softer material beneath. During reassembly, a washer also prevents galling between the fastener head and the mating surface. Verify the serial number or application, then call (562) 693-7748. The part is listed as a hardware washer, a common type used in mechanical assemblies.
