Bowmalloy KP80417 Sae Uss Flat Washer 9/16 Inch

Product Description

The BOWMALLOY KP80417 is a 9/16 inch SAE USS flat washer manufactured from Grade 9 carbon steel with a clear zinc chromate finish. This washer is designed to distribute fastener load across a bearing surface, reducing the risk of damage to the workpiece and improving joint integrity. It meets ASTM F436 standards and is suited for structural and general-purpose bolted connections where both SAE and USS dimensional tolerances are acceptable. The inside diameter measures 0.5880 inches and the outside diameter measures 1.1800 inches, with a thickness of 0.1250 inches. The zinc chromate finish provides moderate corrosion resistance for indoor and light outdoor applications. Licensed tradespeople and journeymen installers stock this washer for routine fastener assemblies across mechanical and structural work.

This flat washer fits 9/16 inch fastener assemblies and is appropriate for use in residential and light commercial construction, HVAC equipment mounting, electrical panel and conduit support work, plumbing fixture installations, and general mechanical assembly. It is sold individually with a minimum order quantity of 50 pieces, making it practical for job-lot procurement. Its dual SAE and USS rating means it covers a wider range of applications where either standard hole pattern is called out on drawings or specifications.

Installation Notes

Installation is performed by any qualified tradesperson working with bolted mechanical or structural assemblies. Always de-energize equipment and relieve system pressure before disassembling any fastened joint. Use appropriate torque values as specified by the equipment manufacturer or applicable code, as no torque specification is supplied with this washer alone. Inspect washers for deformation or coating damage before installation and discard any that show cracks or excessive corrosion.
