It features a 5\/8-11 UNC thread profile with 3-1\/2 inches of length under the head, providing solid clamping force in through-bolted connections. Manufactured from Grade 2 steel with an uncoated finish, this bolt meets ANSI\/ASME B18.2.1 standards. The square head design allows engagement with pipe wrenches, open-end wrenches, and socket tools where a hex head may not be accessible or appropriate. Licensed tradespeople working in mechanical, structural, and HVAC support applications will find this bolt suited to everyday fastening tasks.\u003c\/p\u003e\n\u003cp\u003eThis square head bolt is used in residential and commercial construction, mechanical equipment mounting, structural framing, and utility installations where UNC fasteners are specified. Its uncoated Grade 2 steel construction makes it appropriate for interior or protected environments. The 5\/8-11 thread size is commonly encountered in equipment anchoring, pipe support brackets, and similar trade applications where coarse-thread fasteners are standard practice.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e5\/8-11 UNC coarse thread for reliable engagement in standard tapped holes and nuts\u003c\/li\u003e\n  \u003cli\u003e3-1\/2 inch length under head suits through-bolting in medium-thickness assemblies\u003c\/li\u003e\n  \u003cli\u003eGrade 2 steel construction meets general-purpose structural fastening requirements\u003c\/li\u003e\n  \u003cli\u003eUncoated finish — intended for dry or protected indoor installations\u003c\/li\u003e\n  \u003cli\u003eMeets ANSI\/ASME B18.2.1 dimensional standards\u003c\/li\u003e\n  \u003cli\u003eSquare head profile allows wrench engagement in tight or awkward access points\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or general-purpose fastener for applications requiring a 5\/8-11 UNC square head bolt with 3-1\/2 inches of length under the head in Grade 2 steel.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is typically performed by licensed mechanical, structural, or HVAC technicians following applicable building and mechanical codes. Always de-energize and isolate any equipment before installing or removing fasteners on live assemblies. Use an appropriately sized open-end wrench, pipe wrench, or socket to torque the bolt evenly — avoid over-tightening, which can strip Grade 2 threads. Uncoated steel fasteners should not be used in wet, corrosive, or exterior environments without appropriate protective measures.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 5\/8-11\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: 3-1\/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\u003eWeight\u003c\/strong\u003e: 0.35 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: 747248BR\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51701806924082,"sku":"747248BR","price":58.38,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/ac4f26919b385e2b03dab4e7f473a414.jpg?v=1788405283","url":"https:\/\/voomisupply.com\/products\/value-collection-747248br-square-head-bolt-5-8-11-unc","provider":"Voomi Supply","version":"1.0","type":"link"}
