It features a 3\/4-10 UNC thread size with a 2-1\/2 inch length under head. The square head profile provides flat bearing surfaces on all four sides, making it well suited for applications where a wrench or pipe wrench grip is needed or where the head must be set into a square recess to prevent rotation. Plumbers, pipefitters, millwrights, and general tradespeople use this fastener in structural assemblies, pipe flanges, machinery frames, and similar heavy-duty connections.\u003c\/p\u003e\u003cp\u003eThis bolt is appropriate for residential and commercial applications where UNC coarse-thread fasteners are specified. It fits typical installations in wood framing with timber connectors, steel fabrication, and mechanical equipment mounting where Grade 2 steel strength is sufficient and surface coating is not required. The uncoated finish suits interior or protected installations where corrosion resistance is not a primary concern.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSquare head profile provides four flat grip surfaces for wrench or pipe wrench engagement\u003c\/li\u003e\n\u003cli\u003e3\/4-10 UNC coarse thread for fast assembly and reliable engagement in standard tapped holes\u003c\/li\u003e\n\u003cli\u003e2-1\/2 inch length under head to suit moderate-depth fastening applications\u003c\/li\u003e\n\u003cli\u003eGrade 2 steel construction meets ANSI\/ASME B18.2.1 dimensional standards\u003c\/li\u003e\n\u003cli\u003eUncoated finish keeps the part ready for field painting, plating, or use as-is in protected environments\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard UNC coarse-thread square head bolt for use in structural, mechanical, and general industrial assemblies requiring a 3\/4-10 thread and 2-1\/2 inch length under head per ANSI\/ASME B18.2.1.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstall using a properly sized open-end, box-end, or pipe wrench on the square head. Power down or de-energize any associated equipment before fastener replacement on mechanical assemblies. Follow applicable structural or mechanical codes when specifying Grade 2 fasteners in load-bearing connections, as higher-grade fasteners may be required by design specifications. Apply thread lubricant or anti-seize only when permitted by the application requirements.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 3\/4-10\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: UNC\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength Under Head\u003c\/strong\u003e: 2-1\/2 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: Uncoated\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStandard\u003c\/strong\u003e: ANSI\/ASME B18.2.1\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 31161600\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.41 pounds\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: R52001278\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51714362343730,"sku":"R52001278","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/d7141a9730dde12806171b00880b7877.jpg?v=1788500251","url":"https:\/\/voomisupply.com\/products\/value-collection-r52001278-square-head-bolt-3-4-10-unc","provider":"Voomi Supply","version":"1.0","type":"link"}
