The shoulder measures 0.625 inches in diameter and 4.25 inches in length, providing a reliable pivot or bearing point for rotating or sliding components. The 1\/2-13 UNC threaded section anchors the fastener securely into a tapped hole. Drive engagement is through a 5\/16-inch hex socket, requiring a hex key or Allen driver for installation. The screw arrives with an uncoated finish. This fastener is installed by machinists, maintenance technicians, and mechanical assembly professionals.\u003c\/p\u003e\n\u003cp\u003eShoulder screws of this type are commonly used in jigs, fixtures, tooling plates, and mechanical assemblies where a shaft, bushing, or linkage component must rotate or slide freely around the shoulder. The 4.25-inch shoulder length accommodates thicker assemblies or stacked components. Typical applications include die sets, cam followers, hinge points, and guide pins in both industrial and precision-manufacturing environments. The Grade 8 alloy steel construction provides high tensile strength suitable for demanding load conditions.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e0.625-inch shoulder diameter provides a precise bearing or pivot surface\u003c\/li\u003e\n  \u003cli\u003e4.25-inch shoulder length accommodates thick assemblies or stacked components\u003c\/li\u003e\n  \u003cli\u003eGrade 8 alloy steel construction for high tensile strength under load\u003c\/li\u003e\n  \u003cli\u003e1\/2-13 UNC thread for positive engagement in standard tapped holes\u003c\/li\u003e\n  \u003cli\u003e5\/16-inch hex socket drive for torque application with standard Allen tools\u003c\/li\u003e\n  \u003cli\u003eMeets ANSI B18.3 and ASME\/ANSI B18.3 and ASTM A574 standards\u003c\/li\u003e\n  \u003cli\u003eUncoated finish; suitable for use as-is or with added corrosion protection\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard shoulder screw conforming to ANSI B18.3, ASME\/ANSI B18.3, and ASTM A574 specifications, making it interchangeable with other compliant 5\/8-inch shoulder diameter, 1\/2-13 UNC shoulder screws used in industrial tooling and mechanical assembly applications.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by hand-threading the screw into a properly tapped 1\/2-13 UNC blind or through hole, then tightening with a 5\/16-inch hex key. Ensure the mating hole is clean and free of debris before installation. Do not use an impact driver on hex socket shoulder screws, as this can damage the socket or over-torque the threaded section. Follow applicable machinery safety lockout\/tagout procedures before servicing any assembly containing this fastener.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShoulder Diameter\u003c\/strong\u003e: 0.625 inches (5\/8 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShoulder Length\u003c\/strong\u003e: 4.25 inches (4-1\/4 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\u003eHead Diameter\u003c\/strong\u003e: 0.875 inches (7\/8 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHead Height\u003c\/strong\u003e: 0.375 inches (3\/8 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: 5\/16 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\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: 0.02 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: 221196BR\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51693777355058,"sku":"221196BR","price":24.63,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/8b56f633564fbca79d86f95a102daeb6.jpg?v=1788317214","url":"https:\/\/voomisupply.com\/products\/value-collection-221196br-shoulder-screw-5-8-in-alloy-steel","provider":"Voomi Supply","version":"1.0","type":"link"}
