The shoulder measures 0.25 inches in diameter and 1 inch in length, with a 10-24 UNC threaded end. The head accepts a 1\/8-inch hex socket drive and measures 3\/8 inches in diameter and 3\/16 inches in height. This fastener meets ASME\/ANSI B18.3, ASTM F835, and IFI 124 standards, making it appropriate for demanding mechanical and industrial assemblies installed by machinists, maintenance technicians, and field engineers.\u003c\/p\u003e\n\u003cp\u003eShoulder screws like the 225013PR are used in fixtures, jigs, dies, and linkage assemblies where a hardened, close-tolerance shaft is needed to serve as a pivot point or guide. The 4140 alloy steel construction provides the hardness and tensile strength required for moderate-to-high load applications. This screw is sold individually with a minimum order quantity of 10 units, making it suitable for production runs, MRO replenishment, and tooling builds across manufacturing and industrial maintenance environments.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e0.25-inch shoulder diameter with 1-inch shoulder length for precise alignment and pivot applications\u003c\/li\u003e\n  \u003cli\u003e4140 alloy steel construction for high tensile strength and wear resistance\u003c\/li\u003e\n  \u003cli\u003e10-24 UNC threaded end for broad compatibility with standard tapped holes\u003c\/li\u003e\n  \u003cli\u003e1\/8-inch hex socket drive for torque application with standard Allen keys or hex bits\u003c\/li\u003e\n  \u003cli\u003eMeets ASME\/ANSI B18.3, ASTM F835, and IFI 124 dimensional and material standards\u003c\/li\u003e\n  \u003cli\u003e3\/8-inch head diameter and 3\/16-inch head height for low-profile clamping\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard shoulder screw for use in mechanical assemblies, fixtures, jigs, and linkages requiring a 1\/4-inch diameter shoulder with a 10-24 UNC threaded end.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is typically performed by machinists or maintenance technicians using a 1\/8-inch hex key or socket bit driver. Ensure the mating tapped hole is clean and free of debris before installation. Do not overtighten, as the shoulder must remain the clamping reference, not the thread.
