The shoulder provides a hardened, smooth bearing surface that allows pivoting, guiding, or locating of mating components with tight dimensional control. Drive engagement is via a 3\/16-inch hex socket. The screw is uncoated and conforms to ASME B18.3 and ASME B1.1 standards, making it a reliable choice for engineered assemblies where dimensional accuracy is required.\u003c\/p\u003e\u003cp\u003eThis shoulder screw is suited for use in jigs, fixtures, machine tools, linkages, and mechanical assemblies where a precise shoulder fit controls movement or positions a component. The 5\/16-18 UNC thread and 1\/2-inch thread length provide secure clamping into a tapped hole, while the rounded head seats flush in standard counterbored applications. Machinists, millwrights, and industrial maintenance technicians commonly install this type of fastener in production equipment and fabricated assemblies.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eGrade 8 alloy steel construction for high tensile strength in demanding applications\u003c\/li\u003e\n\u003cli\u003e3\/8-inch shoulder diameter with precision-ground tolerance for accurate bearing and locating\u003c\/li\u003e\n\u003cli\u003e3\/16-inch hex socket drive for positive torque engagement with a standard hex key\u003c\/li\u003e\n\u003cli\u003e5\/16-18 UNC thread meets ASME B1.1 for reliable engagement with standard tapped holes\u003c\/li\u003e\n\u003cli\u003eUncoated finish suitable for use as-is or with customer-applied coatings\u003c\/li\u003e\n\u003cli\u003eConforms to ASME B18.3 and ASME B1.1 standards\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or standard-fit shoulder screw for industrial machinery, jigs, fixtures, and mechanical assemblies requiring a 3\/8-inch shoulder diameter and 5\/16-18 UNC thread.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by qualified machinists or maintenance technicians using a 3\/16-inch hex key or socket driver. Ensure the receiving tapped hole is clean, correctly sized to 5\/16-18 UNC, and that the counterbore matches the shoulder diameter before installation. De-energize and lock out all equipment before accessing fastener locations in powered machinery. Do not exceed the torque capacity appropriate for Grade 8 alloy steel fasteners of this thread size as specified by applicable engineering standards.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eProduct Type\u003c\/strong\u003e: Shoulder Screw\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\u003eShoulder Diameter\u003c\/strong\u003e: 0.3750 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShoulder Length\u003c\/strong\u003e: 0.5000 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 5\/16-18\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: 0.5000 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 1.2500 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: 0.5430 to 0.5620 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHead Height\u003c\/strong\u003e: 0.2500 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: 3\/16 inches\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\u003ch4\u003eStandard Information\u003c\/h4\u003e\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: 08036\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HOLO-KROME","offers":[{"title":"Default Title","offer_id":51729505419570,"sku":"08036","price":12478.89,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/f8ab588813e23fa423edd5e5b1de4d6c.jpg?v=1788705368","url":"https:\/\/voomisupply.com\/products\/holo-krome-08036-shoulder-screw-3-8-in-alloy-steel-hex-socket","provider":"Voomi Supply","version":"1.0","type":"link"}
