The square head profile provides a larger bearing surface than a standard hex head, making it easier to drive with a wrench or hold in place against a mating surface. With a 1 inch length under head and a unified coarse thread form, this bolt is suited for general-purpose fastening in fabrication, structural assembly, and mechanical maintenance applications. Installation is straightforward for any trade professional working with threaded fastener assemblies.\u003c\/p\u003e\n\u003cp\u003eThis bolt is commonly used in light structural connections, equipment mounting, and general mechanical assemblies where a square head profile is required or specified. The 1\/4-20 UNC thread is one of the most common coarse-thread sizes in North American trade applications, compatible with standard 1\/4-20 nuts, inserts, and tapped holes. It is typically installed by millwrights, maintenance technicians, pipefitters, and general construction tradespeople. This SKU ships as a single piece but carries a minimum order quantity of 100 units, making it appropriate for bulk fastener restocking.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSquare head profile provides increased torque surface and anti-rotation grip in slotted or recessed applications\u003c\/li\u003e\n  \u003cli\u003e1\/4-20 UNC thread form matches the most widely used coarse-thread standard in North American fastener applications\u003c\/li\u003e\n  \u003cli\u003eGrade 2 steel construction suitable for general-purpose, non-critical fastening applications\u003c\/li\u003e\n  \u003cli\u003eUncoated finish — no plating or coating that could affect thread tolerance or dimensional fit\u003c\/li\u003e\n  \u003cli\u003eManufactured to ANSI\/ASME B18.2.1 dimensional standards for consistent head geometry and thread accuracy\u003c\/li\u003e\n  \u003cli\u003eMinimum order quantity of 100 units supports bulk inventory and job-lot purchasing\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or standard-stock fastener for any application requiring a 1\/4-20 UNC square head bolt conforming to ANSI\/ASME B18.2.1 dimensional specifications.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation requires a standard open-end or adjustable wrench sized for a 1\/4-20 square head bolt. Ensure mating tapped holes or nuts conform to 1\/4-20 UNC thread standards before installation to avoid cross-threading. Follow applicable torque guidelines from the equipment manufacturer or structural design specification for the fastened assembly. Do not substitute Grade 2 fasteners in applications that specify higher-grade hardware without engineering review.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 1\/4-20\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: 1 inch\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\u003eDimensional Standard\u003c\/strong\u003e: ANSI\/ASME B18.2.1\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.0174 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 31161600\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: R52001047\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51698084512050,"sku":"R52001047","price":1440.65,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/0f7bcbca380c9badb7d72ef39bf2fc3f.jpg?v=1788357506","url":"https:\/\/voomisupply.com\/products\/value-collection-r52001047-square-head-bolt-1-4-20-unc","provider":"Voomi Supply","version":"1.0","type":"link"}
