The shoulder measures 0.625 inches in diameter and 0.75 inches in length, providing a close-tolerance shank for guiding mating components. Drive engagement is via a 5\/16 inch hex socket, and the thread is 1\/2-13 UNC. The uncoated finish suits dry or lightly oiled environments. This screw is installed by machinists, maintenance technicians, and fabricators working on jigs, fixtures, dies, and mechanical assemblies.\u003c\/p\u003e\u003cp\u003eThis shoulder screw is suited for use in industrial machinery, tooling fixtures, hinged mechanisms, and assemblies requiring a precision pivot or linear guide point. The 4140 alloy steel construction provides good tensile strength and wear resistance for demanding mechanical environments. Each package contains 25 pieces, making it practical for production line maintenance or shop stock replenishment. It is sold with a minimum order quantity of 1 package.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eShoulder diameter of 0.625 inches provides close-tolerance fit for alignment and bearing applications\u003c\/li\u003e\n\u003cli\u003eShoulder length of 0.75 inches suits standard fixture and pivot configurations\u003c\/li\u003e\n\u003cli\u003e1\/2-13 UNC thread for broad compatibility with standard tapped holes\u003c\/li\u003e\n\u003cli\u003e4140 alloy steel construction for high strength and wear resistance\u003c\/li\u003e\n\u003cli\u003e5\/16 inch hex socket drive for positive torque engagement with standard Allen wrenches\u003c\/li\u003e\n\u003cli\u003eMeets ANSI B18.3, ASME\/ANSI B18.3, and ASTM A574 standards\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard shoulder screw for industrial fixtures, jigs, dies, and mechanical assemblies requiring a 0.625 inch shoulder diameter and 1\/2-13 UNC threaded engagement.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by machinists or maintenance technicians using a 5\/16 inch hex key or socket driver.
