WSHR FLT .31 .38 .88 .083 (Yale YT220083878)

A worn flat washer can allow fastener loosening under vibration, leading to component misalignment or detachment. This aftermarket replacement part references the Yale catalog and cross-references part number YT220083878. A flat washer distributes load evenly under a fastener head or nut. Its plain mechanical function is to reduce surface friction and prevent galling between mating surfaces. A generic failure consequence is that a missing or crushed washer can cause a bolted joint to lose preload, resulting in rattling or eventual part separation. In a typical usage context, these washers are placed between a fastener and the part being secured to protect the surface from damage. Verify the serial number or application, then call (562) 693-7748. The item ships at approximately 0.004 pounds.
