The hex socket drive accepts a 5\/32-inch hex key for installation. With a 1\/4-20 UNC thread and a 0.438-inch thread length, this fastener is engineered to function as a precision pivot, guide, or linkage pin in mechanical assemblies. The uncoated finish is standard for grade 8 alloy steel. Overall length is 1.907 inches. Manufactured to ASME B1.1 and ASME B18.3 standards, it suits applications where dimensional accuracy and load capacity are critical.\u003c\/p\u003e\n\u003cp\u003eShoulder screws of this type are used in industrial machinery, jigs and fixtures, tooling, and automation equipment where a hardened, precision-ground shank serves as a bearing surface or pivot point. The 5\/16-inch shoulder diameter and grade 8 material make this screw appropriate for moderate- to high-load pivot and guide-pin applications. Machinists, tool-and-die makers, maintenance technicians, and mechanical assemblers typically install these fasteners in production tooling, cam mechanisms, and link assemblies across manufacturing and industrial maintenance environments.\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 durability\u003c\/li\u003e\n  \u003cli\u003e5\/16-inch shoulder diameter (0.3120 inches decimal) provides a precision bearing surface\u003c\/li\u003e\n  \u003cli\u003e1-1\/4-inch shoulder length suits common pivot and guide-pin applications\u003c\/li\u003e\n  \u003cli\u003e1\/4-20 UNC thread with 0.438-inch thread length for secure fastening\u003c\/li\u003e\n  \u003cli\u003e5\/32-inch hex socket drive for installation with a standard hex key\u003c\/li\u003e\n  \u003cli\u003eMeets ASME B1.1 and ASME B18.3 dimensional standards\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard ASME B18.3 shoulder screw for use in mechanical assemblies requiring a 5\/16-inch precision shoulder with a 1\/4-20 UNC threaded end.

Ensure the mating clearance hole matches the 5\/16-inch shoulder diameter for correct fit and function. Thread the fastener into a pre-tapped 1\/4-20 UNC hole and torque to the value specified in the applicable assembly drawing or engineering documentation. Do not use an impact driver, as this may damage the hex socket recess or the thread.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShoulder Diameter\u003c\/strong\u003e: 5\/16 inches (0.3120 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShoulder Length\u003c\/strong\u003e: 1-1\/4 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 1\/4-20 UNC\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Length\u003c\/strong\u003e: 0.438 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 1.907 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHead Diameter\u003c\/strong\u003e: 0.419 to 0.438 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHead Height\u003c\/strong\u003e: 0.209 to 0.219 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\/32 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHead Type\u003c\/strong\u003e: Rounded\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: 08026\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HOLO-KROME","offers":[{"title":"Default Title","offer_id":51730432491826,"sku":"08026","price":13026.12,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/d79fe5b337caaaf85255a0810612e71d.jpg?v=1788717366","url":"https:\/\/voomisupply.com\/products\/holo-krome-08026-shoulder-screw-5-16-in-alloy-steel-hex-socket","provider":"Voomi Supply","version":"1.0","type":"link"}
