The threaded portion is sized 1\/2-13 UNC with a 3\/4 inch thread length, giving an overall length of 3-1\/8 inches. Drive engagement is a 5\/16 inch hex socket in a rounded head measuring 7\/8 inch in diameter and 3\/8 inch in height. The uncoated alloy steel construction meets Material Grade 8 and conforms to ASME B1.1 and ASME B18.3. This fastener is installed by machinists, maintenance technicians, and mechanical assemblers wherever a precision-ground shoulder is needed to serve as a locating pin, pivot, or guide for moving components.\u003c\/p\u003e\n\u003cp\u003eShoulder screws of this type are common in jigs, fixtures, machine assemblies, and industrial equipment where a smooth, hardened bearing surface is required through a mating bore. The 5\/8 inch shoulder provides a precise cylindrical surface that controls alignment and allows rotational or sliding motion of bushings, links, or other retained components. The 1\/2-13 thread engages a tapped hole in the base material, clamping the assembly while leaving the shoulder free to function as a bearing surface. This screw is sold individually and is appropriate for both original equipment and maintenance replacement applications.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e5\/8 inch shoulder diameter with a precision-ground 2 inch shoulder length for accurate component alignment\u003c\/li\u003e\n  \u003cli\u003e1\/2-13 UNC thread at 3\/4 inch thread length conforms to ASME B1.1 thread standard\u003c\/li\u003e\n  \u003cli\u003eMaterial Grade 8 alloy steel for high tensile strength in demanding mechanical applications\u003c\/li\u003e\n  \u003cli\u003e5\/16 inch hex socket drive for positive torque engagement with standard Allen keys or hex bit drivers\u003c\/li\u003e\n  \u003cli\u003eUncoated finish — suitable for post-installation plating, coating, or use as-is in dry or lubricated assemblies\u003c\/li\u003e\n  \u003cli\u003eMeets ASME B18.3 socket screw dimensional standards\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or new-installation shoulder screw for mechanical assemblies, fixtures, and jigs requiring a 5\/8 inch shoulder diameter and 1\/2-13 UNC threaded engagement.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is typically performed by machinists or maintenance technicians using a 5\/16 inch hex key or hex socket driver. Ensure the mating bore is sized to accept a 5\/8 inch shoulder with an appropriate fit tolerance before installation. Do not apply torque to the shoulder surface — drive only through the hex socket in the head. Follow applicable facility or equipment manufacturer torque guidelines for 1\/2-13 Grade 8 fasteners.\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: 2 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 1\/2-13\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: UNRC\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: 3.1250 inches (3-1\/8 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHead Type\u003c\/strong\u003e: Rounded\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\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: ASME B1.1, ASME B18.3\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 31161619\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\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: 08106\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HOLO-KROME","offers":[{"title":"Default Title","offer_id":51727241347378,"sku":"08106","price":26.44,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/659484b55698eb47d893d282cd3a7e87.jpg?v=1788675263","url":"https:\/\/voomisupply.com\/products\/holo-krome-08106-shoulder-screw-5-8-in-alloy-steel-hex-socket","provider":"Voomi Supply","version":"1.0","type":"link"}
