Manufactured from steel with a zinc-plated finish, this washer distributes load across the fastener bearing surface, protecting the mated material and reducing the risk of pull-through. It meets USS (United States Standard) dimensional standards, which specify a larger outer diameter relative to the screw size compared to SAE washers. With a 9\/16-inch inner diameter, 1-3\/8-inch outer diameter, and a thickness of 0.1094 inches, this washer suits general-purpose structural and mechanical assembly applications.\u003c\/p\u003e\n\u003cp\u003eThis washer is used across a wide range of trade and industrial applications including HVAC equipment mounting, plumbing fixture installation, electrical panel and equipment anchoring, and general structural fastening. The USS series is the standard choice when a larger bearing surface is needed to prevent fastener heads or nuts from pulling into softer substrates such as wood framing, sheet metal, and composite panels. It is handled by maintenance technicians, pipefitters, electricians, and general contractors in both residential and light commercial settings.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eUSS flat washer standard — larger OD than SAE for increased load distribution\u003c\/li\u003e\n  \u003cli\u003eSteel construction with zinc-plated finish for corrosion resistance in general-purpose environments\u003c\/li\u003e\n  \u003cli\u003e9\/16-inch inner diameter fits standard 1\/2-inch fasteners with proper clearance\u003c\/li\u003e\n  \u003cli\u003e1-3\/8-inch outer diameter provides wide bearing surface to protect mating material\u003c\/li\u003e\n  \u003cli\u003e0.1094-inch thickness meets USS dimensional tolerances for consistent stack height in assemblies\u003c\/li\u003e\n  \u003cli\u003eInch measurement system — compatible with standard SAE and USS fastener hardware\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or general-use flat washer for applications requiring a 1\/2-inch screw size USS flat washer with inch-system fastener hardware.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstall with the appropriate 1\/2-inch bolt or screw using standard hand tools or a socket set. Ensure the washer seats flush against the bearing surface before torquing the fastener. Zinc plating provides mild corrosion protection and is not rated for continuous outdoor exposure in high-moisture or chemically active environments — consult applicable fastener standards for those applications. No power shutdown is required for washer installation, but follow all applicable site safety protocols when working on mechanical or electrical assemblies.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWasher Type\u003c\/strong\u003e: USS Flat Washer\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eScrew Size\u003c\/strong\u003e: 1\/2 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInner Diameter\u003c\/strong\u003e: 9\/16 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOuter Diameter\u003c\/strong\u003e: 1-3\/8 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThickness\u003c\/strong\u003e: 0.1094 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFinish Coating\u003c\/strong\u003e: Zinc-Plated\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSystem of Measurement\u003c\/strong\u003e: Inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 4.95 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 31161807\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: VALUE COLLECTION\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: R52000123\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51723006476594,"sku":"R52000123","price":63.83,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/fcdf478030633616f90cdae6972c2344.jpg?v=1788599166","url":"https:\/\/voomisupply.com\/products\/value-collection-r52000123-uss-flat-washer-1-2-in-steel","provider":"Voomi Supply","version":"1.0","type":"link"}
