The shoulder measures 0.75 inches in diameter and 3 inches in length, providing a reliable pivot or guide pin surface in jigs, fixtures, and mechanical assemblies. The 5\/8-11 UNC threaded section pulls the fastener tight while the uncoated alloy steel shoulder absorbs radial loads. A hex socket drive accepts a 3\/8 inch drive tool for controlled installation in confined spaces.\u003c\/p\u003e\n\u003cp\u003eThis shoulder screw suits industrial and mechanical maintenance applications where a precise bearing diameter is required. Common install scenarios include fixture plates, die sets, linkage assemblies, and equipment panels. The 1 inch head diameter and 0.5 inch head height seat flush against standard counterbored holes. Machinists, millwrights, and maintenance technicians typically specify this fastener when a hardened, close-tolerance pin-and-thread combination is needed in a single component.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e0.75 inch shoulder diameter with 3 inch shoulder length for extended bearing surface\u003c\/li\u003e\n  \u003cli\u003eGrade 8 alloy steel construction for high tensile and shear strength\u003c\/li\u003e\n  \u003cli\u003e5\/8-11 UNC thread for compatibility with standard tapped holes\u003c\/li\u003e\n  \u003cli\u003eHex socket drive accepts a 3\/8 inch hex key or socket driver\u003c\/li\u003e\n  \u003cli\u003eUncoated finish suitable for secondary plating or use as-is in dry environments\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-dimension shoulder screw for use in any application requiring a 3\/4 inch shoulder diameter, 3 inch shoulder length, and 5\/8-11 UNC threaded engagement, conforming to ANSI B18.3 and ASME\/ANSI B18.3 dimensional standards.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstall using a 3\/8 inch hex key or socket driver; do not use an impact driver, as overtorquing can damage the threaded section or distort the precision shoulder. Ensure the mating counterbore is machined to the correct tolerance for a 0.75 inch shoulder before installation. De-energize or lock out any equipment per applicable OSHA lockout\/tagout procedures before replacing fasteners in live machinery. Inspect the mating bore and thread for wear or contamination prior to installation.\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: 3 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\u003eThread Standard\u003c\/strong\u003e: UNC\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\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: 221232BR\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51709982146866,"sku":"221232BR","price":18.84,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/212d709b31587976e3ec6180e3108201.jpg?v=1788462825","url":"https:\/\/voomisupply.com\/products\/value-collection-221232br-shoulder-screw-3-4-in-alloy-steel","provider":"Voomi Supply","version":"1.0","type":"link"}
