It features a 0.75-inch shoulder diameter and a 1.75-inch shoulder length, making it suitable for use as a precision pivot, spacer, or guide pin in mechanical assemblies. The threaded portion uses a 5\/8-11 UNC thread standard. The head measures 1 inch in diameter and 0.5 inches in height. This fastener is left uncoated and meets ANSI B18.3 and ASTM A574 standards. It is installed with a 3\/8-inch hex socket drive. Machinists, maintenance technicians, and industrial assemblers work with this type of shoulder screw in fixture and tooling applications.\u003c\/p\u003e\n\u003cp\u003eShoulder screws of this size are commonly used in jigs, fixtures, dies, and mechanical linkages where a precise cylindrical bearing surface is required. The ground shoulder acts as a bearing journal or a positive stop, allowing mating components to rotate or slide along the shoulder without thread engagement. This particular screw suits medium-to-heavy-duty applications where Grade 8 alloy steel strength and tight dimensional tolerances are needed. It is sold individually with a minimum order quantity of one.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e0.75-inch shoulder diameter with 1.75-inch shoulder length for precise fit in bored holes\u003c\/li\u003e\n  \u003cli\u003eGrade 8 alloy steel construction meets ANSI B18.3, ASME\/ANSI B18.3, and ASTM A574 standards\u003c\/li\u003e\n  \u003cli\u003e5\/8-11 UNC threaded shank for secure clamping in standard tapped holes\u003c\/li\u003e\n  \u003cli\u003e3\/8-inch hex socket drive allows torque application in confined spaces\u003c\/li\u003e\n  \u003cli\u003eUncoated finish — suitable for further treatment or use where coating is not required\u003c\/li\u003e\n  \u003cli\u003e1-inch head diameter and 0.5-inch head height provide a solid seating surface\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard ANSI B18.3 hex socket shoulder screw for use in mechanical assemblies, jigs, dies, and fixtures that require a 3\/4-inch shoulder diameter and a 5\/8-11 UNC threaded engagement.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed with a 3\/8-inch hex key or socket drive. Ensure the mating bored hole is sized to the shoulder diameter tolerance specified by ANSI B18.3 for proper fit. De-energize or lock out any machinery before fastener installation or replacement. Do not use an impact driver, as this may damage the hex socket recess or over-torque the threaded section.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\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: 1.75 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 inch\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: Alloy Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: 8\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: 0.37 pounds\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: 221217BR\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51699225231666,"sku":"221217BR","price":17.62,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/6be32fcb120b4fcfbdbab3b0b5e39546.jpg?v=1788373776","url":"https:\/\/voomisupply.com\/products\/value-collection-221217br-shoulder-screw-3-4-in-alloy-steel","provider":"Voomi Supply","version":"1.0","type":"link"}
