It features a 5\/8-inch shoulder diameter and an 8-inch shoulder length, making it well suited for applications that require a precise cylindrical bearing surface. The thread is 1\/2-13 UNC, and the hex socket drive accepts a 5\/16-inch hex key. The head measures 7\/8 inch in diameter and 3\/8 inch in height. This fastener is manufactured to ANSI B18.3, ASME\/ANSI B18.3, and ASTM A574 standards, ensuring dimensional and mechanical consistency for industrial and mechanical assembly work.\u003c\/p\u003e\n\u003cp\u003eShoulder screws of this type are used across a wide range of mechanical assembly applications including linkage pivot points, jig and fixture construction, die sets, and shafting guides where a hardened, close-tolerance cylindrical surface is needed. The 8-inch shoulder length is longer than standard, making it appropriate for deep-stack assemblies, guide rails, and applications that require an extended bearing journal. Maintenance technicians, tool and die makers, and machine builders are the typical installers of this fastener type.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e5\/8-inch shoulder diameter with a precision ground cylindrical surface for bearing and pivot use\u003c\/li\u003e\n  \u003cli\u003e8-inch shoulder length accommodates deep-stack or extended-reach assembly applications\u003c\/li\u003e\n  \u003cli\u003e4140 alloy steel construction provides high tensile strength and wear resistance\u003c\/li\u003e\n  \u003cli\u003e1\/2-13 UNC thread engages standard tapped holes in steel and aluminum structures\u003c\/li\u003e\n  \u003cli\u003e5\/16-inch hex socket drive for torque application with a standard Allen key\u003c\/li\u003e\n  \u003cli\u003eUncoated finish suitable for use where secondary coating or plating will be applied\u003c\/li\u003e\n  \u003cli\u003eMeets ANSI B18.3, ASME\/ANSI B18.3, and ASTM A574 dimensional and mechanical standards\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or direct-use shoulder screw for mechanical assemblies requiring a 5\/8-inch diameter shoulder, 1\/2-13 UNC threaded end, and hex socket drive in conformance with ANSI B18.3 specifications.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by machinists, tool and die makers, or maintenance technicians using a 5\/16-inch hex key or socket driver. Ensure the mating tapped hole is clean and sized for 1\/2-13 UNC thread before installation. Do not use an impact driver on the hex socket, as this may damage the socket recess or over-torque the thread. Confirm shoulder bore clearance fits the 5\/8-inch diameter within the tolerance required for the bearing or pivot application before final assembly.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eProduct Type\u003c\/strong\u003e: Shoulder Screw\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShoulder Diameter\u003c\/strong\u003e: 5\/8 inch (0.6250 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShoulder Length\u003c\/strong\u003e: 8 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 1\/2-13 UNC\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: 5\/16 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHead Diameter\u003c\/strong\u003e: 7\/8 inch (0.8750 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHead Height\u003c\/strong\u003e: 3\/8 inch (0.3750 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: 4140 Alloy Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFinish\u003c\/strong\u003e: Uncoated\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\u003eWeight\u003c\/strong\u003e: 0.01 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: 711253BR\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51697417355570,"sku":"711253BR","price":53.85,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/e6128c5b4e51643a53d170ddf5d07290.jpg?v=1788351455","url":"https:\/\/voomisupply.com\/products\/value-collection-711253br-shoulder-screw-5-8-in-8-in-4140-steel","provider":"Voomi Supply","version":"1.0","type":"link"}
