Built to ASTM F436 standards, this washer delivers consistent load distribution and surface protection across a wide range of fastening applications. The Bowma-Guard finish provides corrosion resistance suited to both indoor and outdoor installations. With a Rockwell C38-42 hardness rating, it handles high-clamp-load assemblies without deforming under torque. Each package contains 200 washers, making this SKU appropriate for job-site stock or production-line use by contractors and tradespeople working with structural or mechanical fastening systems.\u003c\/p\u003e\u003cp\u003eThis SAE flat washer is used wherever a 1\/4 inch fastener requires a broader bearing surface to prevent pull-through or surface damage. Typical applications include HVAC equipment mounting, structural connections, plumbing fixture installations, and general mechanical assemblies requiring inch-series hardware. The SAE outside diameter provides a wider bearing surface compared to USS equivalents at the same screw size, which is relevant when working with softer base materials or oversized clearance holes.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eASTM F436 fastener standard for consistent dimensional and mechanical compliance\u003c\/li\u003e\n\u003cli\u003eRockwell C38-42 hardness resists deformation under high-clamp-load conditions\u003c\/li\u003e\n\u003cli\u003eBowma-Guard finish provides corrosion resistance for extended service life\u003c\/li\u003e\n\u003cli\u003eSAE washer type with 0.2710 inch ID and 0.6250 inch OD for proper 1\/4 inch screw fitment\u003c\/li\u003e\n\u003cli\u003e0.0730 inch thickness maintains consistent stack height in assemblies\u003c\/li\u003e\n\u003cli\u003ePackage quantity of 200 supports bulk job-site or shop inventory needs\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with 1\/4 inch screw fasteners in inch-series mechanical and structural assemblies conforming to SAE washer dimensional standards.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by licensed tradespeople or qualified mechanics using standard hand or power tools. Always de-energize or depressurize the assembly before disassembling fastened joints. Follow applicable code requirements, including NEC or IFGC references where fastener hardware is used in equipment mounting. Do not substitute SAE washers for USS or metric equivalents without verifying inside diameter, outside diameter, and thickness compatibility with the fastener and joint design.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eWasher Type\u003c\/strong\u003e: SAE\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eScrew Size\u003c\/strong\u003e: 1\/4 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInside Diameter\u003c\/strong\u003e: 0.2710 inches (9\/32 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOutside Diameter\u003c\/strong\u003e: 0.6250 inches (5\/8 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThickness\u003c\/strong\u003e: 0.0730 inches (5\/64 inch)\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 9\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFinish\u003c\/strong\u003e: Bowma-Guard\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHardness\u003c\/strong\u003e: Rockwell C38-42\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFastener Standard\u003c\/strong\u003e: ASTM F436\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSystem of Measurement\u003c\/strong\u003e: Inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 200\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.01 pounds\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: BOWMALLOY\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: BOW500113\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"BOWMALLOY","offers":[{"title":"Default Title","offer_id":51971187802418,"sku":"BOW500113","price":142.64,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/3cf537aecc08208936202a9946378782_80dada8a-305b-4043-af2c-4c4827043a03.jpg?v=1789954372","url":"https:\/\/voomisupply.com\/products\/bowmalloy-bow500113-sae-flat-washer-1-4-in-steel-200pk","provider":"Voomi Supply","version":"1.0","type":"link"}
