It features a 1\/2-inch shoulder diameter and a 7-inch shoulder length, making it suited for applications that demand precise shaft alignment, pivoting, or guided motion. The threaded end is 3\/8-16 UNC, and the hex socket head accepts a 1\/4-inch drive. Shoulder screws of this type are installed by machinists, millwrights, and maintenance technicians in industrial and mechanical assembly work where tight tolerances on the shoulder are critical to function.\u003c\/p\u003e\n\u003cp\u003eThis fastener is used in industrial machinery, jigs and fixtures, linkage assemblies, and precision mechanical components where a hardened, accurately ground shoulder is required to act as a pivot point, guide pin, or spacer. The 7-inch shoulder length accommodates deeper assemblies or stacked components. The uncoated alloy steel construction is appropriate for controlled indoor environments or applications where a secondary coating will be applied on-site.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e1\/2-inch shoulder diameter with 7-inch shoulder length for deep-reach pivot and guide applications\u003c\/li\u003e\n  \u003cli\u003e3\/8-16 UNC threaded end for secure fastening into tapped holes\u003c\/li\u003e\n  \u003cli\u003e4140 alloy steel construction for high strength and wear resistance\u003c\/li\u003e\n  \u003cli\u003e1\/4-inch hex socket drive for precise torque application with standard Allen keys or hex bits\u003c\/li\u003e\n  \u003cli\u003e3\/4-inch head diameter and 5\/16-inch head height provide a low-profile bearing surface\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 for use in industrial machinery, tooling, and mechanical assemblies requiring a 1\/2-inch diameter shoulder, 7-inch shoulder length, and 3\/8-16 UNC thread engagement.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is typically performed by machinists or maintenance technicians using a 1\/4-inch hex key or hex bit driver. Ensure the receiving tapped hole is clean and the thread depth is sufficient for the 3\/8-16 thread before installation. Do not use the shoulder as the primary clamping surface; the shoulder is a precision ground locating feature. Power down and de-energize any equipment before servicing fasteners in live assemblies.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShoulder Diameter\u003c\/strong\u003e: 0.5000 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShoulder Length\u003c\/strong\u003e: 7 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\u003eHead Diameter\u003c\/strong\u003e: 0.7500 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHead Height\u003c\/strong\u003e: 0.3125 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: 1\/4 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: 4140 Alloy Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFinish\u003c\/strong\u003e: Uncoated\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.52 pounds\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\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: 711283PR\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51714441249074,"sku":"711283PR","price":2628.35,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/a4afa97b218091476fbfb5cab381c494.jpg?v=1788501499","url":"https:\/\/voomisupply.com\/products\/value-collection-711283pr-shoulder-screw-1-2x7-3-8-16-4140-steel","provider":"Voomi Supply","version":"1.0","type":"link"}
