It features a 1-1\/4-7 UNC thread size with a 6-inch length under head, providing substantial grip for demanding connections. Manufactured from Grade 2 steel with an uncoated finish, this bolt conforms to ANSI\/ASME B18.2.1 standards. The square head profile allows for secure engagement with a wrench or socket in tight or high-torque fastening scenarios where a standard hex head may not provide adequate purchase.\u003c\/p\u003e\n\u003cp\u003eThis bolt is suited for general-purpose structural and industrial fastening where large-diameter coarse-thread fasteners are required. Typical applications include timber framing, heavy equipment assembly, agricultural machinery, and structural steel connections. The uncoated steel finish is appropriate for interior or controlled-environment installations where corrosion exposure is limited. Installers working in wet or corrosive environments should evaluate whether additional corrosion protection is needed for the application.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e1-1\/4-7 UNC coarse thread for strong, reliable engagement in steel and structural applications\u003c\/li\u003e\n  \u003cli\u003e6-inch length under head provides ample fastening depth for thick material assemblies\u003c\/li\u003e\n  \u003cli\u003eSquare head profile allows firm wrench grip and resists rotation during installation\u003c\/li\u003e\n  \u003cli\u003eGrade 2 steel construction meets ANSI\/ASME B18.2.1 dimensional standards\u003c\/li\u003e\n  \u003cli\u003eUncoated finish suitable for dry or controlled-environment use\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a general-purpose large-diameter coarse-thread square head bolt for structural, industrial, and mechanical fastening applications requiring a 1-1\/4-7 UNC thread specification.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is typically performed by millwrights, ironworkers, or maintenance mechanics using appropriate hand or power tools rated for large-diameter fasteners. A properly sized square socket or adjustable wrench should be used to seat the bolt head and prevent slippage. Follow applicable torque guidelines from the design engineer or structural specifications for the assembly. Ensure mating nuts and hardware share the same thread standard and grade rating before installation.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 1-1\/4-7 UNC\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength Under Head\u003c\/strong\u003e: 6 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHead Type\u003c\/strong\u003e: Square Head\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\u003eStandard\u003c\/strong\u003e: ANSI\/ASME B18.2.1\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 2.581 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: R52001017\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51715860169010,"sku":"R52001017","price":26.37,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/560c5d06e992c87fd5fe7ecfe522b754.jpg?v=1788519125","url":"https:\/\/voomisupply.com\/products\/value-collection-r52001017-square-head-bolt-1-1-4-7-unc","provider":"Voomi Supply","version":"1.0","type":"link"}
