It is threaded 3\/8-16 UNC and measures 2-3\/4 inches in overall length. The hex drive accepts a 3\/16-inch hex key. Manufactured from alloy steel for high tensile strength and resistance to shear forces, this fastener meets ASME\/ANSI B18.3 and ASTM F912 standards. It is a fully headless design, seating flush or below the surface of the clamped part. Machinists, millwrights, and maintenance technicians commonly install this fastener during assembly and repair work on rotating machinery and mechanical sub-assemblies.\u003c\/p\u003e\n\u003cp\u003eThis set screw is appropriate for general industrial, mechanical, and maintenance applications where a 3\/8-16 UNC threaded socket is required and a cup point is specified to bite into the shaft surface for positive retention. It suits both light and moderate duty shaft-locking tasks in manufacturing, HVAC equipment assemblies, and similar mechanical systems. The 2-3\/4-inch length accommodates thicker hubs or collars where a shorter screw would not provide adequate thread engagement.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e3\/8-16 UNC thread for broad compatibility with standard threaded sockets\u003c\/li\u003e\n  \u003cli\u003e2-3\/4-inch overall length suits deeper hub or collar applications\u003c\/li\u003e\n  \u003cli\u003eCup point tip bites into shaft surface for positive rotational and axial retention\u003c\/li\u003e\n  \u003cli\u003e3\/16-inch hex drive — standard hex key installation, no special tooling required\u003c\/li\u003e\n  \u003cli\u003eAlloy steel construction provides high tensile and torsional strength\u003c\/li\u003e\n  \u003cli\u003eMeets ASME\/ANSI B18.3 and ASTM F912 dimensional and mechanical standards\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard 3\/8-16 UNC cup point set screw suitable for any threaded socket or mechanical assembly specifying ASME\/ANSI B18.3 compliant headless hex drive fasteners of this size.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed with a 3\/16-inch hex key or Allen driver; ensure the driver is fully seated before applying torque to avoid rounding the socket. De-energize and lock out all equipment before accessing any shaft or rotating assembly per applicable OSHA lockout\/tagout procedures. Clean the shaft surface and threaded bore of debris before installation to ensure proper seating of the cup point.
