The shoulder measures 1 inch in diameter and 2-1\/2 inches in length, with a 3\/4-10 UNC threaded end and a hex socket drive requiring a 1\/2 inch drive tool. The head diameter is 1-5\/16 inches with a head height of 5\/8 inch. The uncoated finish makes this screw suitable for applications where additional coatings or platings will be applied by the installer. This fastener is typically installed by machinists, maintenance technicians, or mechanical assemblers.\u003c\/p\u003e\u003cp\u003eThis shoulder screw is used in industrial machinery, tooling fixtures, jigs, and mechanical assemblies where a precise cylindrical shoulder must bear load, guide movement, or act as a pivot point. The 4140 alloy steel construction provides high tensile strength and wear resistance suited to demanding mechanical environments. It is appropriate for both light and heavy manufacturing settings, as well as maintenance and repair operations where an OEM-spec shoulder screw is required.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e1 inch shoulder diameter with 2-1\/2 inch shoulder length for precision fit in bored or reamed holes\u003c\/li\u003e\n\u003cli\u003e3\/4-10 UNC threaded end for secure engagement in steel or cast components\u003c\/li\u003e\n\u003cli\u003e1\/2 inch hex socket drive for high-torque installation with a standard Allen or hex key\u003c\/li\u003e\n\u003cli\u003e4140 alloy steel construction for high strength and wear resistance\u003c\/li\u003e\n\u003cli\u003eUncoated finish for compatibility with post-installation surface treatments\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 conforming to ANSI B18.3 and ASME\/ANSI B18.3 dimensional specifications, suitable for use in industrial machinery, tooling, and mechanical assemblies requiring a 1 inch diameter shoulder fastener with a 3\/4-10 UNC thread.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified machinist or mechanical technician. Ensure the receiving hole is bored or reamed to the appropriate tolerance for the 1 inch shoulder diameter before installation.
