The screw features a 5\/8-inch shoulder diameter and a 3-1\/4-inch shoulder length, providing a reliable bearing or pivot surface in mechanical assemblies. The 1\/2-13 UNC threaded section measures 3\/4 inch in length. An overall length of 4-3\/8 inches and an uncoated finish make this fastener well suited for use in machinery, fixtures, tooling, and industrial equipment. It is installed by machinists, millwrights, and maintenance technicians using a 5\/16-inch hex key.\u003c\/p\u003e\n\u003cp\u003eThis shoulder screw is used in industrial and commercial mechanical assemblies where a precisely ground shoulder serves as a shaft, guide pin, or pivot point. Common applications include jigs, fixtures, cams, linkages, and conveyor components. The rounded head profile and hex socket drive allow installation in counterbored holes with limited overhead clearance. It is sold and packaged individually, making it suitable for low-quantity repair and maintenance work as well as production builds.\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\u003e5\/8-inch shoulder diameter with 3-1\/4-inch shoulder length for precision fit in bored holes\u003c\/li\u003e\n  \u003cli\u003e1\/2-13 UNC thread at 3\/4-inch length for secure clamping engagement\u003c\/li\u003e\n  \u003cli\u003e5\/16-inch hex socket drive for installation with standard Allen keys or hex drivers\u003c\/li\u003e\n  \u003cli\u003eUncoated finish — no plating buildup that would affect shoulder diameter tolerance\u003c\/li\u003e\n  \u003cli\u003eMeets ASME B18.3 and ASME B1.1 dimensional standards\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or standard-fit shoulder screw for industrial machinery, tooling fixtures, and mechanical assemblies requiring a 5\/8-inch shoulder diameter and 1\/2-13 UNC thread per ASME B18.3.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eShoulder screws are typically installed by machinists or maintenance technicians using a calibrated 5\/16-inch hex key or driver. De-energize and lock out all equipment before removing or installing fasteners in live machinery per applicable OSHA lockout-tagout procedures. The mating counterbore should be machined to the shoulder diameter tolerance specified in ASME B18.3 to ensure proper fit and function. Do not use an impact driver on socket head shoulder screws, as this can damage the hex socket recess or over-stress the threaded section.\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: 0.6250 inches (5\/8 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShoulder Length\u003c\/strong\u003e: 3.2500 inches (3-1\/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\u003eThread Length\u003c\/strong\u003e: 0.7500 inches (3\/4 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 4.3750 inches (4-3\/8 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHead Diameter\u003c\/strong\u003e: 0.8750 inches (7\/8 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHead Height\u003c\/strong\u003e: 0.3750 inches (3\/8 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHead Type\u003c\/strong\u003e: Rounded\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\u003eThread Standard\u003c\/strong\u003e: UNRC\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: ASME B1.1, ASME B18.3\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: HOLO-KROME\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 08116\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HOLO-KROME","offers":[{"title":"Default Title","offer_id":51737456836914,"sku":"08116","price":31.2,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/61712f432426b13da865b6be99d80820.jpg?v=1788788797","url":"https:\/\/voomisupply.com\/products\/holo-krome-08116-shoulder-screw-5-8-in-alloy-steel-hex-socket","provider":"Voomi Supply","version":"1.0","type":"link"}
