The shoulder measures 1 inch in diameter and 1-1\/4 inches in length, providing a close-tolerance bearing surface for bushings, bearings, or link plates. Drive engagement uses a 1\/2-inch hex socket drive. The uncoated finish preserves dimensional accuracy. Machinists, maintenance technicians, and industrial assemblers install this fastener where a hardened, accurately ground cylindrical shoulder is required to locate or retain a mating component under load.\u003c\/p\u003e\n\u003cp\u003eThis shoulder screw is suited for use in jigs, fixtures, linkages, cams, and pivot assemblies across general manufacturing, tooling, and maintenance environments. The 3\/4-10 UNC thread engages tapped bores in steel plates and frames. The 5\/8-inch head height and 1-5\/16-inch head diameter provide a solid seating surface. It is appropriate for both original equipment builds and field replacement in industrial machinery where a standardized alloy-steel shoulder fastener is specified.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e1-inch shoulder diameter with 1-1\/4-inch shoulder length for precise fit in close-tolerance bores\u003c\/li\u003e\n  \u003cli\u003e4140 alloy steel construction for high tensile strength and fatigue resistance\u003c\/li\u003e\n  \u003cli\u003e3\/4-10 UNC thread for secure engagement in standard tapped steel bores\u003c\/li\u003e\n  \u003cli\u003e1\/2-inch hex socket drive for installation with standard Allen or hex-bit tooling\u003c\/li\u003e\n  \u003cli\u003eUncoated finish preserves dimensional tolerances out of the box\u003c\/li\u003e\n  \u003cli\u003eMeets ANSI B18.3 and 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 replacement or direct-install shoulder screw for mechanical assemblies requiring a 1-inch diameter, 1-1\/4-inch length alloy-steel shoulder fastener with a 3\/4-10 UNC threaded end, conforming to ANSI B18.3 and ASTM A574 specifications.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is typically performed by machinists or maintenance technicians using a 1\/2-inch hex key or socket bit driver. Ensure the mating bore diameter matches the shoulder diameter to the specified tolerance before assembly. De-energize and lock out any machinery before installing or replacing shoulder screws in live equipment. Do not exceed the rated thread engagement depth for the 3\/4-10 UNC thread to avoid stripping the tapped bore.\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\u003eMaterial\u003c\/strong\u003e: 4140 Alloy Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShoulder Diameter\u003c\/strong\u003e: 1 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShoulder Length\u003c\/strong\u003e: 1.25 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 3\/4-10\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: 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: 1.3125 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHead Height\u003c\/strong\u003e: 0.625 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: 0.01 pounds\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: 711155BR\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51721583526194,"sku":"711155BR","price":43.37,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/4fdb013d332048d12ea5cb6aa9a49042_144b4dde-fd9f-43ee-b835-da1ff2abadc9.jpg?v=1788578920","url":"https:\/\/voomisupply.com\/products\/value-collection-711155br-shoulder-screw-1-in-4140-alloy-steel","provider":"Voomi Supply","version":"1.0","type":"link"}
