It features a 3\/8-16 UNC thread specification and a 2-1\/2 inch length under head, making it suited for applications that require a wrench-gripping bolt head with high torque transfer. Constructed from Grade 2 steel with an uncoated finish, this bolt delivers standard tensile strength for low- to medium-stress installations. Machinists, millwrights, pipefitters, and general contractors commonly use square head fasteners where pipe fittings, flanges, or timber connections call for this traditional bolt profile.\u003c\/p\u003e\n\u003cp\u003eThis bolt is appropriate for use in residential and light commercial construction, equipment fabrication, and maintenance applications. The square head profile seats firmly against square-hole fittings and timber framing, reducing the tendency to rotate during installation. It is a practical choice wherever a traditional square head fastener is specified by plan, code, or original equipment design. Each bolt is sold individually, with a minimum order quantity of 50 pieces per order.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e3\/8-16 UNC thread form for standard inch-series fastener compatibility\u003c\/li\u003e\n  \u003cli\u003e2-1\/2 inch length under head suits medium-depth clamping applications\u003c\/li\u003e\n  \u003cli\u003eSquare head profile allows wrench engagement and resists spinning in square-hole applications\u003c\/li\u003e\n  \u003cli\u003eGrade 2 steel construction meets standard tensile requirements for general-purpose use\u003c\/li\u003e\n  \u003cli\u003eUncoated finish suitable for indoor, dry, or subsequently finished installations\u003c\/li\u003e\n  \u003cli\u003eLightweight at approximately 0.086 pounds per bolt\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a general-purpose replacement or service fastener for assemblies specifying a 3\/8-16 UNC square head bolt with a 2-1\/2 inch length under head in Grade 2 uncoated steel.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eSquare head bolts are typically installed by machinists, ironworkers, or general contractors using an open-end or adjustable wrench. Ensure mating threads are clean and free of debris before installation. Apply fastener torque in accordance with applicable Grade 2 torque specifications from the relevant ASME or AISC standard for the assembly. Do not use impact tools at full power on Grade 2 fasteners, as this can exceed the material yield strength.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 3\/8-16\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: 2-1\/2 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHead Style\u003c\/strong\u003e: Square\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eGrade\u003c\/strong\u003e: 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\u003eWeight\u003c\/strong\u003e: 0.086 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: R52001179\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51721011298610,"sku":"R52001179","price":5740.94,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/9dfb4ac24f9a4d47caa4b3a9a2eb8d0e.jpg?v=1788572251","url":"https:\/\/voomisupply.com\/products\/value-collection-r52001179-square-head-bolt-3-8-16-unc","provider":"Voomi Supply","version":"1.0","type":"link"}
