Machined to a 3\/4-10 UNC thread size with 3 inches of length under the head, this bolt meets ANSI\/ASME B18.2.1 dimensional standards. Constructed from Grade 2 steel with an uncoated finish, it suits standard structural and mechanical assemblies. Licensed tradespeople and maintenance technicians install this fastener across a range of industrial, commercial, and utility applications where square head geometry simplifies torquing in tight or awkward spaces.\u003c\/p\u003e\n\u003cp\u003eThis bolt is suited for use in structural framing, mechanical equipment mounting, and utility installations where UNC thread engagement and a large wrench-bearing head are needed. The square head profile provides four wrench contact surfaces, making it practical in applications where a hex head is less accessible. Typical install environments include HVAC equipment supports, plumbing equipment bases, electrical enclosure mounting, and general structural ironwork.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e3\/4-10 UNC thread for standard coarse-thread engagement with nuts and tapped holes\u003c\/li\u003e\n  \u003cli\u003e3 inches length under head for adequate thread engagement in thick stock\u003c\/li\u003e\n  \u003cli\u003eSquare head geometry provides four wrench flats for reliable torquing in confined areas\u003c\/li\u003e\n  \u003cli\u003eGrade 2 steel construction meets general-purpose structural load requirements\u003c\/li\u003e\n  \u003cli\u003eUncoated finish suitable for dry indoor environments or where field coating will be applied\u003c\/li\u003e\n  \u003cli\u003eConforms to ANSI\/ASME B18.2.1 dimensional standards\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard UNC square head fastener compatible with 3\/4-10 threaded nuts, couplers, and tapped components conforming to ANSI\/ASME B18.2.1 specifications.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by mechanics, millwrights, plumbers, or HVAC technicians depending on the application. Use an appropriately sized box-end or adjustable wrench on the square head to avoid rounding corners during torquing. De-energize and depressurize any equipment before replacing structural fasteners in live systems. Apply a flat washer and properly rated nut to achieve full clamping force; do not substitute mismatched thread forms.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 3\/4-10 UNC\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength Under Head\u003c\/strong\u003e: 3 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Grade 2 Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFinish\u003c\/strong\u003e: Uncoated\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: UNC\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDimensional Standard\u003c\/strong\u003e: ANSI\/ASME B18.2.1\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.49 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\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: R52001281\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51720469676338,"sku":"R52001281","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/94c50482963f1d6215cf623c00797896.jpg?v=1788564517","url":"https:\/\/voomisupply.com\/products\/value-collection-r52001281-square-head-bolt-3-4-10-unc","provider":"Voomi Supply","version":"1.0","type":"link"}
