WASHER (Yale YT221769)

YT221769: A worn washer can compromise the clamping force in a bolted joint, leading to loosening over time. This aftermarket replacement part references the Yale catalog number YT221769. The washer distributes the load of a threaded fastener across a wider surface area. A plain mechanical function of this type is to prevent galling between the fastener head and the mating surface. A concrete generic failure consequence is that a missing or crushed washer can allow the fastener to embed into the softer material, reducing preload. During a routine fastener inspection, a deformed washer may indicate over-torque or surface contamination. Verify the serial number or application, then call (562) 693-7748.
