Metric Blue UST202006 M10 Standard Flat Washer

Product Description

The METRIC BLUE UST202006 is an M10 standard flat washer manufactured from alloy steel. It provides load distribution and surface protection at the bearing face of a bolt or nut, reducing the risk of fastener pull-through and surface damage. With an inside diameter of 0.453 inches, an outside diameter of 0.7874 inches, and a thickness of 0.1181 inches, this washer meets the dimensional requirements of metric M10 fastener assemblies. It conforms to ASTM F436 and ASTM F606M standards, making it appropriate for structural and industrial fastening applications where material and dimensional compliance are required.

This washer is used in residential, commercial, and industrial construction and maintenance applications wherever M10 metric fasteners are employed. Typical install scenarios include structural steel connections, equipment mounting, and mechanical assemblies that call for a metric-dimensioned flat washer. It is sold individually but carries a minimum order quantity of 100 pieces, making it suited for contractors and trades professionals stocking hardware for ongoing project work.
