The shoulder measures 1.25 inches in diameter and 2.75 inches in length, providing a precise locating pin or pivot point within mechanical assemblies. The 7\/8-9 UNC threaded section locks the fastener in place, while the 5\/8-inch hex socket drive and a 1.75-inch head diameter allow for high-torque installation with standard hex keys. This fastener is installed by machinists, maintenance technicians, and mechanical assemblers across a wide range of industrial and OEM applications.\u003c\/p\u003e\n\u003cp\u003eThe 711207BR is suited for use in jigs, fixtures, linkages, die sets, and machine components where a hardened, close-tolerance shoulder is needed to guide movement or align mating parts. The uncoated 4140 alloy steel construction offers the strength required for load-bearing pivot and locating functions in both light industrial and heavy-duty manufacturing environments. It is sold individually and is appropriate wherever a large-diameter shoulder screw meeting ANSI B18.3 and ASME\/ANSI B18.3 standards is specified.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e1.25-inch shoulder diameter provides a precision bearing and locating surface\u003c\/li\u003e\n  \u003cli\u003e2.75-inch shoulder length suits deep fixture and linkage applications\u003c\/li\u003e\n  \u003cli\u003e4140 alloy steel construction delivers high tensile strength and wear resistance\u003c\/li\u003e\n  \u003cli\u003e7\/8-9 UNC thread for secure clamping engagement\u003c\/li\u003e\n  \u003cli\u003e5\/8-inch hex socket drive for high-torque installation with standard hex keys\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 industrial machinery, jigs, fixtures, die sets, and mechanical assemblies requiring a 1.25-inch diameter shoulder with a 7\/8-9 UNC threaded end conforming to ANSI B18.3 specifications.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is typically performed by machinists or maintenance technicians using a 5\/8-inch hex key. Ensure the mating bore is machined to the appropriate tolerance for the 1.25-inch shoulder diameter before installation. Verify thread engagement depth is adequate for the application load before torquing. Follow applicable ASME and facility safety procedures when working with press-fit or close-tolerance fasteners in machinery.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShoulder Diameter\u003c\/strong\u003e: 1.25 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShoulder Length\u003c\/strong\u003e: 2.75 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 7\/8-9 UNC\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHead Diameter\u003c\/strong\u003e: 1.75 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHead Height\u003c\/strong\u003e: 0.75 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: 5\/8 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\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: 711207BR\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51691392958770,"sku":"711207BR","price":70.54,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/4fdb013d332048d12ea5cb6aa9a49042.jpg?v=1788284391","url":"https:\/\/voomisupply.com\/products\/value-collection-711207br-shoulder-screw-4140-alloy-steel","provider":"Voomi Supply","version":"1.0","type":"link"}
