SAE flat washers provide a wider bearing surface than USS washers, distributing fastener load across a broader area to protect the workpiece and reduce the risk of pull-through. The zinc plating delivers corrosion resistance for both indoor and light outdoor service. With an inside diameter of 1-3\/8 inches, an outside diameter of 2-1\/2 inches, and a thickness of 0.192 inches, this washer meets standard SAE dimensional specifications for the 1-1\/4 inch screw size. It is a general-purpose hardware component used by trade professionals across mechanical, structural, and equipment assembly applications.\u003c\/p\u003e\n\u003cp\u003eThis SAE flat washer is suited for use in residential and commercial construction, mechanical equipment assembly, HVAC mounting applications, plumbing and pipe support installations, and general structural fastening where a 1-1\/4 inch fastener is specified. The zinc-plated finish makes it appropriate for indoor environments and areas with limited moisture exposure. It is installed by plumbers, pipefitters, HVAC technicians, electricians, and general contractors wherever load distribution under a fastener head or nut is required.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSAE flat washer profile provides wider load-bearing surface compared to standard USS pattern\u003c\/li\u003e\n  \u003cli\u003eGrade 2 steel construction for reliable strength in general-purpose fastening\u003c\/li\u003e\n  \u003cli\u003eZinc-plated finish for corrosion resistance in low-to-moderate moisture environments\u003c\/li\u003e\n  \u003cli\u003e1-3\/8 inch inside diameter sized for 1-1\/4 inch screw or bolt\u003c\/li\u003e\n  \u003cli\u003e2-1\/2 inch outside diameter for broad load distribution\u003c\/li\u003e\n  \u003cli\u003e0.192 inch thickness meets standard SAE dimensional tolerances\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with 1-1\/4 inch screws and bolts in standard SAE fastening applications across mechanical, structural, and trade installation scenarios.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eFlat washers are installed by placing them over the fastener shank before threading the nut or driving into a tapped hole. Ensure the washer inside diameter is compatible with the fastener shank diameter before installation. Follow applicable fastening torque requirements specified by the equipment manufacturer or relevant codes such as AISC or ASME B18 standards. Inspect the washer seating surface for burrs or debris that could affect load distribution prior to final torque.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWasher Type\u003c\/strong\u003e: SAE 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: 1-3\/8 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOutside Diameter\u003c\/strong\u003e: 2-1\/2 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\u003eUNSPSC Code\u003c\/strong\u003e: 31161807\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 10 pounds\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: FWSIS1250-10LBBX\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51700463075634,"sku":"FWSIS1250-10LBBX","price":80.08,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/a5e97d052863949b645aaeb7c41ec681.jpg?v=1788390634","url":"https:\/\/voomisupply.com\/products\/value-collection-fwsis1250-10lbbx-sae-flat-washer-steel","provider":"Voomi Supply","version":"1.0","type":"link"}
