Made from Grade 2 steel with a zinc-plated finish, this washer distributes load across a wider bearing surface than standard SAE washers, reducing fastener pull-through and surface damage. The zinc coating provides basic corrosion resistance suitable for dry and mildly corrosive environments. With an inside diameter of 1.368 inches, an outside diameter of 3.03 inches, and a thickness of 0.192 inches, this washer meets USS dimensional standards for 1-1\/4 inch screw and bolt assemblies. Installation requires no special tooling beyond standard wrenches or impact equipment.\u003c\/p\u003e\u003cp\u003eThis washer is commonly used in construction, equipment assembly, HVAC equipment mounting, plumbing fixture installation, and general maintenance applications where a larger bearing surface is required. The USS (United States Standard) pattern is the go-to choice when working with coarse or rough-cut surfaces, oversized holes, or where load distribution is a priority over compact fit. It is appropriate for both indoor structural use and sheltered outdoor applications where the zinc finish provides adequate protection.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eUSS flat washer pattern for maximum load distribution compared to SAE-style washers\u003c\/li\u003e\n\u003cli\u003eGrade 2 steel construction provides reliable strength for general-purpose fastening\u003c\/li\u003e\n\u003cli\u003eZinc-plated finish offers basic corrosion resistance in dry and mildly corrosive environments\u003c\/li\u003e\n\u003cli\u003eInside diameter of 1.368 inches fits 1-1\/4 inch screws and bolts with proper clearance\u003c\/li\u003e\n\u003cli\u003eOutside diameter of 3.03 inches and 0.192 inch thickness meet USS dimensional standards\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with 1-1\/4 inch USS-pattern screw and bolt assemblies in general industrial and construction applications.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by any trade professional using standard hand or power tools. Always place the washer flat against the mating surface with the bolt head or nut seated squarely on the washer face. Inspect mating surfaces for burrs or debris before assembly to ensure proper seating and accurate torque transfer. Follow applicable mechanical or structural codes for fastener torque requirements specific to the assembly.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\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: 1-1\/4 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInside Diameter\u003c\/strong\u003e: 1.368 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOutside Diameter\u003c\/strong\u003e: 3.03 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThickness\u003c\/strong\u003e: 0.192 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: Grade 2\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\u003eWeight\u003c\/strong\u003e: 1 pound\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 31161807\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\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: FWUIS1250-5LBBX\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51701023965490,"sku":"FWUIS1250-5LBBX","price":77.27,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/780bb985a25c22125f0b816f06611ab9.jpg?v=1788396949","url":"https:\/\/voomisupply.com\/products\/value-collection-fwuis1250-5lbbx-uss-flat-washer","provider":"Voomi Supply","version":"1.0","type":"link"}
