USS flat washers feature a larger, wider body compared to SAE flat washers, which are machined to a tighter specification with a smaller outside diameter. This USS designation makes the 09417 well-suited for general-purpose bolted connections where maximum load spreading is a priority.\u003c\/p\u003e\n\n\u003ch3\u003eTechnical Specifications\u003c\/h3\u003e\n\u003ctable\u003e\n  \u003ctr\u003e\n\u003cth\u003eMPN\u003c\/th\u003e\n\u003ctd\u003e09417\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003ctr\u003e\n\u003cth\u003eBrand\u003c\/th\u003e\n\u003ctd\u003eMidwest Fastener\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003ctr\u003e\n\u003cth\u003eInner Diameter\u003c\/th\u003e\n\u003ctd\u003e3\/4 inch\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003ctr\u003e\n\u003cth\u003eOuter Diameter\u003c\/th\u003e\n\u003ctd\u003e2 inches\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003ctr\u003e\n\u003cth\u003eThread Size\u003c\/th\u003e\n\u003ctd\u003eUSS\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003ctr\u003e\n\u003cth\u003eMaterial\u003c\/th\u003e\n\u003ctd\u003eSteel\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003ctr\u003e\n\u003cth\u003eFinish\u003c\/th\u003e\n\u003ctd\u003eZinc\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003ctr\u003e\n\u003cth\u003eHardness \/ Grade\u003c\/th\u003e\n\u003ctd\u003eGrade 2 \/ A307\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003ctr\u003e\n\u003cth\u003ePackage Size\u003c\/th\u003e\n\u003ctd\u003e20 pieces\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003ctr\u003e\n\u003cth\u003ePackage Weight\u003c\/th\u003e\n\u003ctd\u003e2.03 lb\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\n\n\u003ch3\u003eTechnical Features\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUSS wide-body profile with 2-inch outer diameter:\u003c\/strong\u003e Provides a larger bearing surface than SAE equivalents, distributing fastener load over a greater area to reduce stress concentration on mated materials.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003e3\/4-inch inner diameter:\u003c\/strong\u003e Sized to fit 3\/4-inch threaded fasteners for a secure, properly aligned fit without excessive play.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSteel construction:\u003c\/strong\u003e Delivers the structural integrity and hardness required for reliable performance in bolted assemblies under mechanical load.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eZinc finish:\u003c\/strong\u003e Provides a corrosion-resistant coating that extends service life in general-purpose environments and protects against surface oxidation.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eGrade 2 \/ A307 hardness rating:\u003c\/strong\u003e Meets established standards for general fastener applications, ensuring consistent mechanical properties across the batch.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSold in 20-piece packages:\u003c\/strong\u003e Allows for efficient procurement for small to mid-scale fastening projects.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eApplications\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003eGeneral construction and structural bolted connections requiring broad load distribution\u003c\/li\u003e\n  \u003cli\u003eWood-to-metal and wood-to-wood fastening assemblies where pull-through resistance is needed\u003c\/li\u003e\n  \u003cli\u003eMachinery assembly and maintenance using 3\/4-inch threaded fasteners\u003c\/li\u003e\n  \u003cli\u003eAny application specifying USS flat washer dimensions in lieu of the tighter-tolerance SAE standard\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Gap Power","offers":[{"title":"Default Title","offer_id":46916628250777,"sku":"09417","price":11.24,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0639\/8138\/7929\/files\/279281219-1.jpg?v=1775339734","url":"https:\/\/gappower.com\/products\/3-4-uss-flat-wash-zn-09417","provider":"Gap Power","version":"1.0","type":"link"}
