The shoulder measures 0.75 inches in diameter and 0.625 inches in length, providing the ground bearing surface that shoulder screws are selected for. Drive engagement is through a 3\/8-inch hex socket. The 5\/8-11 UNC threaded section pulls the screw firmly into the tapped hole, leaving the shoulder exposed to serve as a bushing, pivot, or guide pin. The uncoated finish is standard for applications where dimensional consistency is the primary requirement. Installed by machinists, maintenance technicians, and assembly professionals across a wide range of mechanical and industrial applications.\u003c\/p\u003e\n\u003cp\u003eThis shoulder screw suits precision mechanical assemblies where a hardened, ground-shoulder fastener is needed to locate components, act as a pivot point, or serve as a sliding guide. Typical installations include jigs and fixtures, cam followers, linkage assemblies, and machine tool components. The 4140 alloy steel construction provides the strength and hardness needed in load-bearing pivot and guide applications. This screw conforms to ANSI B18.3 and ASME\/ANSI B18.3 standards, making it a recognized specification-grade fastener for industrial use.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e0.75-inch shoulder diameter provides precise, ground bearing surface for location and pivot use\u003c\/li\u003e\n  \u003cli\u003e0.625-inch shoulder length sized for shallow-clearance assemblies\u003c\/li\u003e\n  \u003cli\u003e4140 alloy steel construction for high tensile strength and wear resistance\u003c\/li\u003e\n  \u003cli\u003e3\/8-inch hex socket drive for standard Allen wrench or hex bit installation\u003c\/li\u003e\n  \u003cli\u003e5\/8-11 UNC thread standard ensures compatibility with common tapped holes\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 specification-grade replacement or new-installation shoulder screw for industrial assemblies, jigs, fixtures, and machinery requiring a 0.75-inch diameter, 0.625-inch shoulder length, 5\/8-11 UNC fastener per ANSI B18.3 and ASME\/ANSI B18.3 standards.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation requires a 3\/8-inch hex key or socket bit driver. The mating tapped hole must be correctly sized for the 5\/8-11 UNC thread before installation. Ensure the shoulder bore in the mating component is reamed or drilled to the appropriate clearance fit for the 0.75-inch shoulder diameter. Do not apply thread-locking compounds to the shoulder surface, as this can interfere with the locating or pivot function of the screw.\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\u003eShoulder Diameter\u003c\/strong\u003e: 0.75 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShoulder Length\u003c\/strong\u003e: 0.625 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 5\/8-11 UNC\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHead Diameter\u003c\/strong\u003e: 1.0 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHead Height\u003c\/strong\u003e: 0.5 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: 3\/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: 711131BR\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51695876342066,"sku":"711131BR","price":24.79,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/0a030453ecaf5b65821039d74f6b9dd5.jpg?v=1788338978","url":"https:\/\/voomisupply.com\/products\/value-collection-711131br-shoulder-screw-4140-alloy-steel","provider":"Voomi Supply","version":"1.0","type":"link"}
