The shoulder diameter measures 0.625 inches with a shoulder length of 1.75 inches, providing a close-tolerance pivot or guide pin surface. The threaded end is 1\/2-13 UNC with a 0.75-inch thread length. Drive engagement is a 5\/16-inch hex socket, accessed with a standard hex key. This fastener carries an uncoated finish and conforms to ASME B1.1 and ASME B18.3 dimensional standards. Mechanical and industrial maintenance technicians install these screws where a precision cylindrical shoulder must carry shear load or act as a locating pin within a machined bore.\u003c\/p\u003e\n\u003cp\u003eShoulder screws like the 08104 are used across industrial machinery, jigs, fixtures, die sets, and automated equipment where a rotating or sliding component must pivot on a hardened, dimensionally consistent shaft. The rounded head profile sits flush against mating surfaces without interference. At 2.875 inches overall length, this screw fits applications requiring a full 1.75-inch exposed shoulder above a standard threaded insert or tapped hole. Maintenance technicians, toolmakers, and millwrights commonly specify this fastener when rebuilding fixtures, replacing worn pivot pins, or constructing new tooling assemblies.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eGrade 8 alloy steel construction for high shear strength and wear resistance\u003c\/li\u003e\n  \u003cli\u003e0.625-inch shoulder diameter with 1.75-inch shoulder length for precision locating and pivoting\u003c\/li\u003e\n  \u003cli\u003e1\/2-13 UNC thread with 0.75-inch thread length for secure engagement in standard tapped holes\u003c\/li\u003e\n  \u003cli\u003e5\/16-inch hex socket drive for controlled torque application with a standard hex key\u003c\/li\u003e\n  \u003cli\u003eRounded head, 0.875 inches in diameter and 0.375 inches tall, for low-profile seating\u003c\/li\u003e\n  \u003cli\u003eMeets ASME B1.1 and ASME B18.3 standards for dimensional accuracy and thread form\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard ASME B18.3 hex socket shoulder screw for use in industrial fixtures, jigs, die sets, and machinery wherever a 0.625-inch shoulder diameter and 1\/2-13 UNC threaded end are specified.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation requires a 5\/16-inch hex key or socket driver rated for the fastener grade. Ensure the receiving bore is machined to a tolerance compatible with a 0.625-inch shoulder for proper fit and function. De-energize and lock out all power and hydraulic sources before servicing any machinery or tooling assembly containing this fastener. Do not substitute a lower-grade fastener in applications where Grade 8 shear strength is specified.\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: 0.625 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShoulder Length\u003c\/strong\u003e: 1.75 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: 0.75 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2.875 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHead Diameter\u003c\/strong\u003e: 0.875 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHead Height\u003c\/strong\u003e: 0.375 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  \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: 08104\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HOLO-KROME","offers":[{"title":"Default Title","offer_id":51731391971634,"sku":"08104","price":22.55,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/09f1fdb61129ed2ed9f658fa4c03531f.jpg?v=1788730420","url":"https:\/\/voomisupply.com\/products\/holo-krome-08104-shoulder-screw-5-8-in-alloy-steel-hex-socket","provider":"Voomi Supply","version":"1.0","type":"link"}
