The shoulder measures 0.750 inches in diameter and 2-1\/2 inches in length, providing a precise bearing surface for pivoting or sliding components. The threaded section carries a 5\/8-11 UNC thread, and the fastener is driven by a 3\/8 inch hex socket drive. At 0.468 pounds, this is a solid, heavy-duty fastener suited to mechanical assemblies requiring tight dimensional tolerances on the shoulder. Machinists, millwrights, and maintenance technicians working on jigs, fixtures, linkages, and motion-control assemblies reach for this type of fastener regularly.\u003c\/p\u003e\n\u003cp\u003eShoulder screws of this size are commonly used in industrial and commercial machinery where a smooth, precisely dimensioned shaft is needed to act as a pivot pin, guide post, or spacer. The 3\/4 inch shoulder diameter and 2-1\/2 inch shoulder length make this fastener appropriate for moderate-to-heavy-duty linkage assemblies, die sets, and fixture components. The grade 8 alloy steel construction handles high shear and tensile loads. This screw is suitable for applications where the shoulder itself carries the load rather than the threaded portion.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eShoulder diameter of 0.750 inches provides a precision bearing and pivot surface\u003c\/li\u003e\n  \u003cli\u003e2-1\/2 inch shoulder length accommodates thicker component stacks in linkage and fixture assemblies\u003c\/li\u003e\n  \u003cli\u003eGrade 8 alloy steel construction for high shear strength and tensile load capacity\u003c\/li\u003e\n  \u003cli\u003e5\/8-11 UNC thread for engagement with standard inch-series tapped holes\u003c\/li\u003e\n  \u003cli\u003e3\/8 inch hex socket drive for positive torque transfer with a standard hex key or socket driver\u003c\/li\u003e\n  \u003cli\u003eUncoated finish; suitable for use as-is or with customer-applied coating where corrosion protection is needed\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style or replacement shoulder screw for mechanical assemblies requiring a 3\/4 inch shoulder diameter, 2-1\/2 inch shoulder length, and 5\/8-11 UNC thread.

The mating tapped hole must be sized for 5\/8-11 UNC thread; verify thread engagement depth before final installation. Do not use the threaded section as the bearing surface — the shoulder must seat fully against the mating bore. Follow facility-specific torque procedures and applicable ASME fastener standards when determining final installation torque.\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 (3\/4 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShoulder Length\u003c\/strong\u003e: 2-1\/2 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 (1 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHead Height\u003c\/strong\u003e: 0.500 inches (1\/2 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: 0.468 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: 221226BR\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51720395718962,"sku":"221226BR","price":19.15,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/7f95110a503118786953a73bab3b8c52.jpg?v=1788563331","url":"https:\/\/voomisupply.com\/products\/value-collection-221226br-shoulder-screw-3-4-in-alloy-steel","provider":"Voomi Supply","version":"1.0","type":"link"}
