WSHR FLT .31 .38 .88 .083 (Toyota TY0120108)

A damaged washer can cause fluid leaks or fastener loosening in mechanical assemblies. During inspection, a flat washer may show deformation or corrosion that compromises its sealing or load-spreading function. The aftermarket replacement part cross-references Toyota part number TY0120108. This washer type provides a plain mechanical function by distributing load under a fastener head. A concrete generic failure consequence is that a worn or missing washer can allow a bolt to loosen under vibration. Keeping a flat washer in sound condition helps maintain consistent clamping force in bolted joints. Verify the serial number or application, then call (562) 693-7748.
