The 1-inch shoulder diameter and 2-inch shoulder length provide a smooth bearing surface for pivoting, sliding, or locating components. The 3\/4-10 UNC threaded shank and 1\/2-inch hex socket drive allow installation with a standard hex key. This screw ships in an uncoated finish. Mechanical assembly technicians and maintenance professionals install this type of fastener in jigs, fixtures, linkages, and machine components.\u003c\/p\u003e\n\u003cp\u003eShoulder screws of this type are used in light and heavy industrial assemblies where a precision-ground shaft surface is needed to guide motion or serve as a pivot point. The 4140 alloy steel construction provides good tensile strength and wear resistance for demanding mechanical applications. The hex socket head keeps the fastener low-profile and allows torque application in confined spaces. Typical installations include die sets, fixture plates, robotic linkages, and mechanical assemblies requiring repeatable positioning.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e1-inch shoulder diameter with 2-inch shoulder length for precise bearing and locating surface\u003c\/li\u003e\n  \u003cli\u003e4140 alloy steel construction for strength and wear resistance\u003c\/li\u003e\n  \u003cli\u003e3\/4-10 UNC thread standard for compatibility with standard tapped holes\u003c\/li\u003e\n  \u003cli\u003e1\/2-inch hex socket drive for installation with a standard Allen or hex key\u003c\/li\u003e\n  \u003cli\u003e5\/8-inch head height and 1-5\/16-inch head diameter for broad seating surface\u003c\/li\u003e\n  \u003cli\u003eUncoated finish; meets ANSI B18.3 and ASTM A574 standards\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or standard-spec shoulder screw for industrial mechanical assemblies requiring a 1-inch diameter, 2-inch shoulder length, 3\/4-10 UNC threaded fastener.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation requires a 1\/2-inch hex key or Allen driver.
