The shoulder measures 5\/16 inches in diameter and 5\/16 inches in length, with a 1\/4-20 UNC threaded end. The head accepts a 5\/32-inch hex socket driver. Constructed from 4140 alloy steel with an uncoated finish, this fastener delivers solid shear strength and dimensional consistency suited to mechanical assemblies, jigs, fixtures, and tooling. It meets ANSI B18.3 and ASTM A574 standards for socket head cap and shoulder screws.\u003c\/p\u003e\n\u003cp\u003eThis shoulder screw is used in mechanical and industrial applications where a precisely dimensioned cylindrical shoulder is needed to locate, guide, or act as a shaft for rotating or sliding components. Common install scenarios include machine tooling, fixture plates, linkage assemblies, and light-duty pivot joints in both production and maintenance environments. Machinists, millwrights, and maintenance technicians are the typical installers. It is sold in a minimum order quantity of 25 pieces, with each unit packaged individually at a weight of 0.02 pounds.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e5\/16-inch shoulder diameter and 5\/16-inch shoulder length for precise locating and pivot use\u003c\/li\u003e\n  \u003cli\u003e1\/4-20 UNC thread for reliable engagement with standard tapped holes\u003c\/li\u003e\n  \u003cli\u003e4140 alloy steel construction provides good tensile strength and wear resistance\u003c\/li\u003e\n  \u003cli\u003e5\/32-inch hex socket drive for standard Allen key or hex bit installation\u003c\/li\u003e\n  \u003cli\u003eUncoated finish — suitable for use as-is or for secondary coating by the installer\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 replacement or new-installation fastener for mechanical assemblies, fixture plates, and tooling applications requiring a 5\/16-inch shoulder diameter with a 1\/4-20 UNC threaded end.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is typically performed by machinists, millwrights, or maintenance technicians using a 5\/32-inch hex key or socket bit. Ensure the mating tapped hole is clean and properly sized for 1\/4-20 UNC thread engagement before installation. Do not overtighten — shoulder screws rely on the shoulder seating flush against the mating surface, not on thread clamp load alone. Verify shoulder clearance fit with the bore or component being located before final assembly.\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: 5\/16 inches (0.3120 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShoulder Length\u003c\/strong\u003e: 5\/16 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 1\/4-20 UNC\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHead Diameter\u003c\/strong\u003e: 7\/16 inches (0.4375 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHead Height\u003c\/strong\u003e: 7\/32 inches (0.2188 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\/32 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: 0.02 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 31161619\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: 711042PR\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51718926729522,"sku":"711042PR","price":5319.3,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/86f967deb03481fa426228c09c530af2.jpg?v=1788556429","url":"https:\/\/voomisupply.com\/products\/value-collection-711042pr-shoulder-screw-5-16-in-1-4-20-alloy-steel","provider":"Voomi Supply","version":"1.0","type":"link"}
