The washer is a thin, flat ring placed under a nut or bolt head. Its plain mechanical function is to distribute the fastener's load over a wider surface area. A generic failure consequence is that a crushed or missing washer can allow the fastener to loosen under vibration. Keeping a washer in sound condition helps maintain consistent torque retention in the assembly. Verify the serial number or application, then call (562) 693-7748.
