The shoulder diameter measures 0.312 inches with a shoulder length of 0.75 inches, providing a precise bearing surface for rotating or sliding components such as linkages, hinges, and pivot points. The 1\/4-20 UNRC thread has a length of 0.438 inches. Drive engagement is via a 5\/32-inch hex socket. The part ships uncoated and meets ASME B1.1 and ASME B18.3 standards. Licensed machinists, millwrights, and maintenance technicians typically install this fastener in both production and MRO settings.\u003c\/p\u003e\n\u003cp\u003eThis shoulder screw is suited for industrial, commercial, and manufacturing environments where a controlled-diameter shoulder is required to serve as a precision shaft, pivot, or guide post. Typical applications include die sets, automation fixtures, cam mechanisms, and any assembly requiring a ground shoulder to align or retain a bearing, bushing, or sliding component. The rounded head profile keeps the fastener low-profile in confined assemblies. With an overall length of 1.407 inches, it fits standard fastener clearances in medium-duty tooling and machinery.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eGrade 8 alloy steel construction for high tensile strength in load-bearing fastener applications\u003c\/li\u003e\n  \u003cli\u003ePrecision shoulder diameter of 0.312 inches for accurate fit in bored or reamed holes\u003c\/li\u003e\n  \u003cli\u003e5\/32-inch hex socket drive for installation with standard Allen keys or hex bit drivers\u003c\/li\u003e\n  \u003cli\u003e1\/4-20 UNRC threaded end with 0.438-inch thread length for secure clamping engagement\u003c\/li\u003e\n  \u003cli\u003eUncoated finish suitable for use as-received or for post-installation treatment\u003c\/li\u003e\n  \u003cli\u003eMeets ASME B1.1 and ASME B18.3 dimensional and thread standards\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or direct-install shoulder screw for mechanical assemblies requiring a 5\/16-inch shoulder diameter, 3\/4-inch shoulder length, and 1\/4-20 threaded end conforming to ASME B18.3.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by machinists, millwrights, or maintenance technicians using a 5\/32-inch hex key or hex socket driver. De-energize and lock out all machinery before servicing any fastener in a live assembly. Ensure the mating hole is bored or reamed to the appropriate tolerance for shoulder screws per ASME B18.3 to achieve proper fit and prevent premature wear. Do not use impact drivers on hex socket shoulder screws, as this can damage the socket or distort the shoulder.\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: 0.312 inches (5\/16 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShoulder Length\u003c\/strong\u003e: 0.75 inches (3\/4 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 1.407 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 1\/4-20 UNRC\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Length\u003c\/strong\u003e: 0.438 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\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\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: 08022\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HOLO-KROME","offers":[{"title":"Default Title","offer_id":51750728171826,"sku":"08022","price":13417.06,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/7a3e4426dde350dbfc45310d4078e479.jpg?v=1788919049","url":"https:\/\/voomisupply.com\/products\/holo-krome-08022-shoulder-screw-5-16-in-alloy-steel-hex-socket","provider":"Voomi Supply","version":"1.0","type":"link"}
