It carries a 1\/2-13 UNC thread size and measures 3-1\/4 inches in length under the head. Manufactured from Grade 2 steel with an uncoated finish, it meets ANSI\/ASME B18.2.1 dimensional standards. Machinists, ironworkers, millwrights, and general contractors install this fastener in applications where the square head provides positive wrench engagement and resistance to rounding under high torque.\u003c\/p\u003e\u003cp\u003eThis bolt is suited for general-purpose structural and industrial fastening in both residential and commercial settings. The square head profile makes it a practical choice in timber framing, equipment mounting, and other applications where clearance limits the use of hex-head tooling or where a through-bolt configuration is preferred. It is sold in a minimum order quantity of 25 pieces per purchase.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e1\/2-13 UNC thread for broad compatibility with standard nuts and tapped holes\u003c\/li\u003e\n\u003cli\u003e3-1\/4 inch length under head suits medium-depth clamping applications\u003c\/li\u003e\n\u003cli\u003eSquare head geometry provides firm wrench purchase and reduces cam-out risk\u003c\/li\u003e\n\u003cli\u003eGrade 2 steel construction meets ANSI\/ASME B18.2.1 dimensional requirements\u003c\/li\u003e\n\u003cli\u003eUncoated finish suitable for indoor or protected installations\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a general-purpose replacement or new-installation square head bolt compatible with any standard 1\/2-13 UNC nut or tapped fitting conforming to ANSI\/ASME B18.2.1.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by mechanics, carpenters, millwrights, or ironworkers using standard open-end, box, or adjustable wrenches sized for a 1\/2-inch square head bolt. Always power down or de-energize any machinery before fastening bolts in proximity to electrical or mechanical drives. Pair with a hardened flat washer and appropriate nut grade to match the bolt grade. Inspect threads for damage before assembly to ensure full engagement.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 1\/2-13 UNC\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength Under Head\u003c\/strong\u003e: 3-1\/4 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: UNC\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGrade\u003c\/strong\u003e: Grade 2\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Steel\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: 0.20 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMinimum Order Quantity\u003c\/strong\u003e: 25 pieces\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: 5052BMQ\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51710226039090,"sku":"5052BMQ","price":24265.2,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/6022abbdb93e502610ea53dbeb51104d_1e5f7204-e612-4310-8cc7-3dabf701551a.jpg?v=1788464533","url":"https:\/\/voomisupply.com\/products\/value-collection-5052bmq-square-head-bolt-1-2-13-unc","provider":"Voomi Supply","version":"1.0","type":"link"}
