The screw features a 3\/4-inch shoulder diameter and a 5-inch shoulder length, providing a smooth, hardened bearing surface for rotating or sliding components. Drive engagement is via a 3\/8-inch hex socket. The uncoated finish is standard for this grade. Licensed trades and industrial maintenance professionals install this fastener in mechanical assemblies, jigs, fixtures, and pivot applications where load-bearing accuracy matters.\u003c\/p\u003e\n\u003cp\u003eThis shoulder screw is suited for use in manufacturing equipment, tooling fixtures, conveyor assemblies, and mechanical linkages that require a precision shoulder as a shaft, pivot pin, or guide. The 5\/8-11 UNC threaded end secures into tapped holes in steel or similarly rated material. The 1-inch head diameter and 1\/2-inch head height provide adequate bearing surface at the fastener head. Single-piece packaging makes it practical as an individual replacement or repair fastener.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eGrade 8 alloy steel construction for high tensile strength and shear resistance\u003c\/li\u003e\n  \u003cli\u003e3\/4-inch shoulder diameter with 5-inch shoulder length for extended bearing surface\u003c\/li\u003e\n  \u003cli\u003e5\/8-11 UNC thread for secure engagement in standard tapped holes\u003c\/li\u003e\n  \u003cli\u003e3\/8-inch hex socket drive compatible with standard Allen wrenches and hex-bit drivers\u003c\/li\u003e\n  \u003cli\u003eUncoated finish — suitable for use as-is or with applied lubricant or coating\u003c\/li\u003e\n  \u003cli\u003eMeets ANSI B18.3, ASME\/ANSI B18.3, and ASTM A574 standards\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or general-use shoulder screw for mechanical assemblies requiring a 3\/4-inch diameter, 5-inch shoulder length, Grade 8 alloy steel fastener with a 5\/8-11 UNC thread and hex socket drive.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by machinists, millwrights, or qualified maintenance technicians using a 3\/8-inch hex key or socket driver. Ensure the mating tapped hole is clean, undamaged, and sized for 5\/8-11 UNC thread before installation. De-energize and lock out any machinery before servicing fasteners in moving assemblies. Do not exceed the torque rating of the mating material — consult engineering specifications for the specific assembly.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShoulder Diameter\u003c\/strong\u003e: 0.7500 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShoulder Length\u003c\/strong\u003e: 5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 5\/8-11 UNC\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHead Diameter\u003c\/strong\u003e: 1.0000 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHead Height\u003c\/strong\u003e: 0.5000 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrive Type\u003c\/strong\u003e: Hex Socket\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrive Size\u003c\/strong\u003e: 3\/8 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Alloy Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: 8\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: 0.02 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: ANSI B18.3, ASME\/ANSI B18.3, ASTM A574\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 31161619\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: 221256BR\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51692865225010,"sku":"221256BR","price":23.56,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/95a383dd4f78de0bda4676786c551080.jpg?v=1788304226","url":"https:\/\/voomisupply.com\/products\/value-collection-221256br-shoulder-screw-3-4-in-alloy-steel","provider":"Voomi Supply","version":"1.0","type":"link"}
