The screw features a 5\/8-inch shoulder diameter and a 4-1\/4-inch shoulder length, with a 1\/2-13 UNRC thread and a 3\/4-inch thread length. The rounded head accepts a 5\/16-inch hex socket drive. Grade 8 alloy steel construction provides the tensile strength needed in demanding mechanical assemblies. The uncoated finish is standard for this type of precision fastener. Machinists, millwrights, and maintenance technicians install these in jigs, fixtures, dies, and mechanical linkages.\u003c\/p\u003e\n\u003cp\u003eShoulder screws of this type are used wherever a precise cylindrical surface is needed to guide, pivot, or retain a mating component. Common applications include die sets, fixture plates, pivot points for levers and linkages, and linear guide assemblies in industrial machinery. The 5\/8-inch shoulder diameter and extended 4-1\/4-inch shoulder length suit this screw for medium to heavy-duty assemblies requiring a long bearing surface. Meets ASME B18.3 and ASME B1.1 standards.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eGrade 8 alloy steel construction for high tensile and shear strength\u003c\/li\u003e\n  \u003cli\u003e5\/8-inch shoulder diameter with precision ground surface for bearing and pivot use\u003c\/li\u003e\n  \u003cli\u003e4-1\/4-inch shoulder length provides extended bearing surface for deep assemblies\u003c\/li\u003e\n  \u003cli\u003e1\/2-13 UNRC thread with 3\/4-inch thread length for secure clamping engagement\u003c\/li\u003e\n  \u003cli\u003e5\/16-inch hex socket drive for installation with standard Allen or hex key tooling\u003c\/li\u003e\n  \u003cli\u003eMeets ASME B18.3 and ASME B1.1 standards\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard shoulder screw replacement or new-installation fastener for industrial jigs, fixtures, dies, and mechanical assemblies requiring a 5\/8-inch precision shoulder diameter with a 1\/2-13 thread.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eShoulder screws should be installed by qualified machinists or maintenance technicians familiar with precision fastener applications. Ensure the mating bore diameter matches the shoulder diameter specification before installation to achieve proper fit and function. Do not overtighten, as the clamping force is applied through the thread length only, not the shoulder. Power down and de-energize any equipment before servicing assemblies that incorporate this fastener.\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: 4.2500 inches (4-1\/4 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 5.3750 inches (5-3\/8 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 1\/2-13 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\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\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: 08119\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HOLO-KROME","offers":[{"title":"Default Title","offer_id":51732991607090,"sku":"08119","price":47.34,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/f4297dc97ab00a1836cbd1e0fd154160.jpg?v=1788750142","url":"https:\/\/voomisupply.com\/products\/holo-krome-08119-shoulder-screw-5-8-in-alloy-steel-hex-socket","provider":"Voomi Supply","version":"1.0","type":"link"}
