Metric Blue UST202007 M12 Standard Flat Washer

Product Description

The METRIC BLUE UST202007 is an M12 standard flat washer manufactured from alloy steel. It distributes load evenly beneath fastener heads and nuts, protecting mating surfaces and reducing the risk of loosening under vibration. With an inside diameter of 0.56 inches, an outside diameter of 1.038 inches, and a thickness of 0.146 inches, this washer conforms to ASTM F436 and ASTM F606M fastener standards. It is suited for structural and mechanical applications where a metric-dimensioned washer is required. Installation is performed by trades working in steel construction, mechanical assembly, and industrial maintenance.

This washer is appropriate for use in residential, commercial, and industrial settings wherever M12 metric fasteners are specified. Typical applications include steel framing connections, equipment mounting, and general mechanical assembly. The alloy steel construction provides the strength needed for load-bearing installations subject to torque and vibration.
