Manufactured from steel with a zinc-plated finish, this washer distributes load across the fastener bearing surface, reducing the risk of pull-through and surface damage in structural and mechanical assemblies. The USS pattern specifies a larger outer diameter relative to screw size compared to SAE washers, making it well suited for applications where broader load distribution is needed. Licensed tradespeople and experienced contractors rely on this washer type in heavy-duty framing, equipment mounting, and general industrial fastening work.\u003c\/p\u003e\n\u003cp\u003eThis washer is used across residential and commercial construction, HVAC equipment mounting, plumbing fixture installations, and general mechanical assembly wherever a 1-3\/8 inch fastener is employed. The 1-1\/2 inch inner diameter provides proper clearance for the screw or bolt shank, while the 3-1\/4 inch outer diameter delivers wide load distribution on wood, metal, or composite substrates. The zinc-plated steel construction offers corrosion resistance suitable for indoor and light-duty outdoor applications.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eUSS flat washer pattern for broader load distribution compared to SAE equivalents\u003c\/li\u003e\n  \u003cli\u003e1-1\/2 inch inner diameter fits 1-3\/8 inch screw or bolt shank with standard clearance\u003c\/li\u003e\n  \u003cli\u003e3-1\/4 inch outer diameter spreads clamping load over a wide bearing area\u003c\/li\u003e\n  \u003cli\u003e0.153 inch thickness provides solid, consistent bearing surface\u003c\/li\u003e\n  \u003cli\u003eZinc-plated steel finish for corrosion resistance in indoor and protected outdoor environments\u003c\/li\u003e\n  \u003cli\u003eInch measurement system; compatible with standard US fastener sizing\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or maintenance stock washer for use with 1-3\/8 inch USS-standard bolts and screws in structural, mechanical, and equipment-mounting applications.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by electricians, plumbers, HVAC technicians, pipefitters, and general contractors as part of fastener assemblies. Always ensure the fastener and washer material are compatible with the substrate to prevent galvanic corrosion. Tighten fasteners to the torque specification called out in the equipment or structural design documentation. Use appropriate hand tools or power tools sized for the fastener being driven.\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: 1-3\/8 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInside Diameter\u003c\/strong\u003e: 1-1\/2 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOutside Diameter\u003c\/strong\u003e: 3-1\/4 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThickness\u003c\/strong\u003e: 0.153 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFinish\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\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: USFW1380025OZ\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51696307962162,"sku":"USFW1380025OZ","price":9291.28,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/8eeb62a9d506a65ad5e62574f59757c9.jpg?v=1788341300","url":"https:\/\/voomisupply.com\/products\/value-collection-usfw1380025oz-uss-flat-washer-steel","provider":"Voomi Supply","version":"1.0","type":"link"}
