It features a 1\/2-13 UNC thread size with a 1-3\/4 inch length under the head, manufactured from Grade 2 steel in an uncoated finish. The square head profile provides a large bearing surface for wrench engagement, making it well suited for installations where a standard hex head is not practical. This bolt conforms to ANSI\/ASME B18.2.1 dimensional standards, ensuring predictable fitment in code-compliant assemblies. It weighs approximately 0.12 pounds per unit.\u003c\/p\u003e\u003cp\u003eSquare head bolts are commonly used in timber framing, equipment mounting, machinery bases, and agricultural fabrication where a wrench or pipe wrench is the primary tightening tool. The 1\/2-13 UNC thread is a coarse-thread designation compatible with standard 1\/2-13 nuts, T-nuts, and tapped holes of the same specification. This configuration is widely specified in light structural and general maintenance applications across construction, plumbing rough-in, and mechanical trade work.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e1\/2-13 UNC coarse thread for broad compatibility with standard hardware\u003c\/li\u003e\n\u003cli\u003e1-3\/4 inch length under head suits moderate-depth fastening applications\u003c\/li\u003e\n\u003cli\u003eGrade 2 steel construction provides adequate strength for general-purpose use\u003c\/li\u003e\n\u003cli\u003eUncoated finish suitable for indoor or protected environments\u003c\/li\u003e\n\u003cli\u003eSquare head profile allows pipe wrench or adjustable wrench engagement\u003c\/li\u003e\n\u003cli\u003eConforms to ANSI\/ASME B18.2.1 dimensional standards\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a general-purpose replacement or stock fastener for use with standard 1\/2-13 UNC nuts and tapped holes meeting ANSI\/ASME B18.2.1 specifications.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is typically performed by mechanics, millwrights, carpenters, or plumbers using a wrench, adjustable wrench, or pipe wrench sized for the square head. Always ensure the mating nut or tapped hole is the correct 1\/2-13 UNC thread specification before installation. Apply thread engagement of at least one bolt diameter for reliable load transfer. De-energize and lock out any associated equipment before fastener service per applicable safety codes.\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: 1-3\/4 inches\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\u003eHead Type\u003c\/strong\u003e: Square\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: 0.12 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMinimum Order Quantity\u003c\/strong\u003e: 50\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\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: 5028BMQ\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51690316857650,"sku":"5028BMQ","price":7126.89,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/7b079c79e2a8c3b6303c7c43e7bdf2bf.jpg?v=1788268639","url":"https:\/\/voomisupply.com\/products\/value-collection-5028bmq-square-head-bolt-1-2-13-unc","provider":"Voomi Supply","version":"1.0","type":"link"}
