The shoulder measures 1\/2 inch in diameter and 1-1\/2 inches in length, providing a controlled bearing or pivot surface. The threaded portion uses a 3\/8-16 UNC thread form. Drive engagement is via a 1\/4 inch hex socket, allowing installation with a standard hex key or Allen driver. The uncoated finish is standard for this grade. This fastener is installed by machinists, maintenance technicians, and assembly professionals in industrial and mechanical applications.\u003c\/p\u003e\n\u003cp\u003eShoulder screws of this type are commonly used in jigs, fixtures, die sets, linkages, and pivot assemblies where a precise shaft diameter is needed to locate or guide a mating component. The 1\/2 inch shoulder acts as the functional bearing surface, while the 3\/8-16 UNC threaded end anchors the screw into a tapped hole. This part is sold in a minimum order quantity of 5 units, with individual package quantity of 1. Suitable for shop floor, toolroom, and manufacturing environments requiring ANSI and ASME-compliant fasteners.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e1\/2 inch shoulder diameter provides a precise, hardened bearing or pivot surface\u003c\/li\u003e\n  \u003cli\u003e1-1\/2 inch shoulder length accommodates standard fixture and die plate thicknesses\u003c\/li\u003e\n  \u003cli\u003eGrade 8 alloy steel construction for high tensile strength and durability\u003c\/li\u003e\n  \u003cli\u003e3\/8-16 UNC threaded end for secure engagement in standard tapped holes\u003c\/li\u003e\n  \u003cli\u003e1\/4 inch hex socket drive for installation with a hex key or Allen driver\u003c\/li\u003e\n  \u003cli\u003eMeets ANSI B18.3, ASME\/ANSI B18.3, and ASTM A574 standards\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard shoulder screw conforming to ANSI B18.3 and ASME\/ANSI B18.3 specifications, suitable for use in any application requiring a 1\/2 inch diameter shoulder, 1-1\/2 inch shoulder length, and 3\/8-16 UNC threaded engagement.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed using a 1\/4 inch hex key or appropriate Allen driver. Ensure the mating tapped hole is clean and correctly sized for 3\/8-16 UNC thread engagement before installation. Do not use an impact driver, as this can damage the hex socket recess or over-torque the fastener. Follow applicable facility or equipment manufacturer torque guidelines for Grade 8 alloy steel fasteners of this thread size.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShoulder Diameter\u003c\/strong\u003e: 1\/2 inch (0.5000 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShoulder Length\u003c\/strong\u003e: 1-1\/2 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 3\/8-16 UNC\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\u003eDrive Type\u003c\/strong\u003e: Hex Socket\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrive Size\u003c\/strong\u003e: 1\/4 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHead Diameter\u003c\/strong\u003e: 3\/4 inch (0.7500 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHead Height\u003c\/strong\u003e: 5\/16 inch (0.3125 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: ANSI B18.3, ASME\/ANSI B18.3, ASTM A574\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.14 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMinimum Order Quantity\u003c\/strong\u003e: 5\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: VALUE COLLECTION\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 221115PR\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51699889013042,"sku":"221115PR","price":2168.47,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/032dfcf9dc6eeb00e209f35cc4b62e72.jpg?v=1788382642","url":"https:\/\/voomisupply.com\/products\/value-collection-221115pr-shoulder-screw-1-2-in-alloy-steel","provider":"Voomi Supply","version":"1.0","type":"link"}
