The screw features a 1-inch shoulder diameter and a 3-1\/2-inch shoulder length, providing a smooth, accurately toleranced bearing surface for rotating or sliding components. Drive engagement is via a 1\/2-inch hex socket, requiring a standard Allen wrench or hex bit. The uncoated finish is suitable for environments where a secondary coating or plating will be applied. Licensed machinists, millwrights, and maintenance technicians are the typical installers.\u003c\/p\u003e\n\u003cp\u003eThis shoulder screw is used in applications that require a tight-tolerance cylindrical shank to serve as a shaft, pivot pin, or guide for bearings, bushings, or other mating components. Common install scenarios include machine frames, fixture tooling, conveyor linkages, and robotic arm assemblies. The 3\/4-10 UNC threaded section anchors the screw into a tapped hole, while the shoulder portion protrudes to carry load. The 5\/8-inch head height and 1-5\/16-inch head diameter provide a stable seating surface against the workpiece.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e1-inch shoulder diameter with 3-1\/2-inch shoulder length for extended bearing surface\u003c\/li\u003e\n  \u003cli\u003e4140 alloy steel construction for high tensile strength and wear resistance\u003c\/li\u003e\n  \u003cli\u003e1\/2-inch hex socket drive for positive torque engagement\u003c\/li\u003e\n  \u003cli\u003e3\/4-10 UNC thread for broad compatibility with standard tapped holes\u003c\/li\u003e\n  \u003cli\u003eUncoated finish — ready for secondary plating, coating, or use as-is in dry environments\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 an OEM-style and aftermarket replacement shoulder screw for industrial machinery, fixtures, and mechanical assemblies requiring a 1-inch diameter shoulder, 3\/4-10 UNC threaded engagement, and a 1\/2-inch hex socket drive.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by machinists, millwrights, or qualified maintenance technicians. Ensure the tapped receiving hole matches the 3\/4-10 UNC thread specification before installation. Use an appropriate 1\/2-inch hex key or socket bit driver and apply thread-locking compound or specified torque to manufacturer assembly drawings — do not rely on feel alone for critical load-bearing joints. De-energize and lock out all machinery before servicing any assembly that includes this fastener.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShoulder Diameter\u003c\/strong\u003e: 1 inch (1.0000 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShoulder Length\u003c\/strong\u003e: 3-1\/2 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 3\/4-10 UNC\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\/2 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHead Diameter\u003c\/strong\u003e: 1-5\/16 inches (1.3125 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHead Height\u003c\/strong\u003e: 5\/8 inch (0.6250 inches)\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\u003eStandards\u003c\/strong\u003e: ANSI B18.3, ASME\/ANSI B18.3, ASTM A574\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\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: 711182BR\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51698084643122,"sku":"711182BR","price":44.54,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/4fdb013d332048d12ea5cb6aa9a49042_67a64bee-6681-48fe-9339-9fd8f3c7f24e.jpg?v=1788357512","url":"https:\/\/voomisupply.com\/products\/value-collection-711182br-shoulder-screw-1-in-4140-alloy-steel","provider":"Voomi Supply","version":"1.0","type":"link"}
