The shoulder measures 0.750 inches in diameter and 4-3\/4 inches in length, providing a smooth bearing surface for rotating or sliding components such as linkages, pivots, and guide assemblies. The 5\/8-11 UNC threaded section secures the fastener in the mating part, while the hex socket drive accepts a 3\/8-inch drive key for installation. Built to Material Grade 8 and manufactured to ANSI B18.3 and ASTM A574 standards, this screw is suited for high-strength mechanical assemblies in industrial and commercial maintenance environments.\u003c\/p\u003e\n\u003cp\u003eThis shoulder screw is used in general industrial and mechanical assembly applications where a precise shoulder diameter is needed to locate, pivot, or guide a mating component. Typical installations include jigs, fixtures, conveyor linkages, tooling assemblies, and machine frames. It is installed by machinists, millwrights, and maintenance technicians working on production equipment, fabrication tooling, or structural mechanical assemblies. The uncoated finish makes it suitable for applications where secondary coating or treatment will be applied, or where bare alloy steel is acceptable for the service environment.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e0.750-inch shoulder diameter provides a close-tolerance bearing surface for rotating and sliding components\u003c\/li\u003e\n  \u003cli\u003e4-3\/4-inch shoulder length accommodates deep pivot or guide applications\u003c\/li\u003e\n  \u003cli\u003e5\/8-11 UNC thread for positive engagement in standard tapped holes\u003c\/li\u003e\n  \u003cli\u003eMaterial Grade 8 alloy steel construction for high tensile strength and hardness\u003c\/li\u003e\n  \u003cli\u003eHex socket drive (3\/8-inch drive size) for torque application with a standard hex key or socket wrench\u003c\/li\u003e\n  \u003cli\u003eMeets ANSI B18.3, ASME\/ANSI B18.3, and ASTM A574 dimensional and strength standards\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard-dimension replacement or new-installation shoulder screw for industrial machinery, tooling fixtures, and mechanical assemblies requiring a 3\/4-inch shoulder diameter and 5\/8-11 UNC thread per ANSI B18.3 specifications.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by machinists or maintenance technicians using a 3\/8-inch hex key or socket driver. Ensure the mating tapped hole is clean, properly sized to 5\/8-11 UNC, and free of debris before threading the screw. De-energize and lock out any equipment before servicing mechanical assemblies containing shoulder screws. Do not use impact drivers on hex socket shoulder screws, as this can damage the socket recess or exceed shoulder tolerance requirements.\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: 0.750 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShoulder Length\u003c\/strong\u003e: 4-3\/4 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\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\u003eHead Diameter\u003c\/strong\u003e: 1.000 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHead Height\u003c\/strong\u003e: 0.500 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\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: 221252BR\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51710225940786,"sku":"221252BR","price":21.1,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/0dfefc4a4fd093b636d95d2a5b9d1c0e.jpg?v=1788464529","url":"https:\/\/voomisupply.com\/products\/value-collection-221252br-shoulder-screw-3-4-in-alloy-steel","provider":"Voomi Supply","version":"1.0","type":"link"}
