Made from steel with a Bowma-Guard finish, it meets ASTM F436 requirements and carries a Rockwell hardness rating of C38-42, making it suitable for high-load bearing applications. The washer features an inside diameter of 0.271 inches, an outside diameter of 0.750 inches, and a thickness of 0.073 inches. Licensed contractors, millwrights, and maintenance technicians working with structural connections will find this washer appropriate for standard load-distribution tasks where a USS-pattern flat washer is specified.\u003c\/p\u003e\u003cp\u003eThis washer fits 1\/4 inch fastener assemblies in residential and light commercial construction, mechanical equipment mounting, and structural steel connections. USS flat washers provide a larger outer diameter than SAE-pattern washers, distributing clamp load over a wider bearing surface. The Bowma-Guard finish provides corrosion resistance suitable for general indoor and protected outdoor installations. This item is sold in a package quantity of 200 pieces.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eUSS pattern with 0.750 inch outside diameter for broad load distribution\u003c\/li\u003e\n\u003cli\u003eSteel construction graded to Material Grade 9 per ASTM F436\u003c\/li\u003e\n\u003cli\u003eRockwell C38-42 hardness for high-load structural use\u003c\/li\u003e\n\u003cli\u003eBowma-Guard finish for corrosion resistance\u003c\/li\u003e\n\u003cli\u003e0.271 inch inside diameter fits standard 1\/4 inch fasteners\u003c\/li\u003e\n\u003cli\u003ePackage quantity of 200 pieces per order\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement and general-use USS flat washer for 1\/4 inch screw and bolt assemblies where ASTM F436 compliance is required.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstall by qualified tradespeople following applicable structural or mechanical fastening codes.
