Threaded 1\/4-28 UNF with an overall length of 7\/16 inches, this fastener uses a 1\/8 inch hex drive and features a cup point tip that bites into the mating surface to resist rotation and axial movement. Made from alloy steel for strength and durability, it meets ASME\/ANSI B18.3 and ASTM F912 standards. Machinists, millwrights, and maintenance technicians install these as standard headless fasteners in precision mechanical work.\u003c\/p\u003e\u003cp\u003eCup point set screws like the 101343PR are used across a wide range of industrial and mechanical applications including motor shaft collars, pulleys, gears, sprockets, and couplings. The 1\/4-28 UNF thread pitch is common in fine-thread applications where vibration resistance and precise clamping are required. This fastener is appropriate for both light-duty and moderate-load assemblies in manufacturing, HVAC equipment, and general industrial maintenance environments.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eCup point tip bites into mating surface for positive rotational and axial hold\u003c\/li\u003e\n\u003cli\u003e1\/4-28 UNF thread for fine-pitch engagement and vibration resistance\u003c\/li\u003e\n\u003cli\u003e1\/8 inch hex (Allen) drive for standard hex key installation\u003c\/li\u003e\n\u003cli\u003eAlloy steel construction for strength in demanding mechanical environments\u003c\/li\u003e\n\u003cli\u003eMeets ASME\/ANSI B18.3 and ASTM F912 fastener standards\u003c\/li\u003e\n\u003cli\u003eHeadless design sits flush or below surface when fully seated\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard 1\/4-28 UNF cup point set screw suitable for collars, hubs, pulleys, and similar mechanical components with a matching 1\/4-28 threaded bore.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstall with a 1\/8 inch hex key; ensure the mating shaft or surface is clean and free of burrs before seating the cup point.
