Value Collection 101343PR Set Screw 1/4-28 X 7/16 in Cup Point

Product Description

The VALUE COLLECTION 101343PR is a cup point set screw designed for secure shaft-to-hub and collar locking applications in mechanical assemblies. 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.

Cup 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.

Key Features

• Cup point tip bites into mating surface for positive rotational and axial hold
• 1/4-28 UNF thread for fine-pitch engagement and vibration resistance
• 1/8 inch hex (Allen) drive for standard hex key installation
• Alloy steel construction for strength in demanding mechanical environments
• Meets ASME/ANSI B18.3 and ASTM F912 fastener standards
• Headless design sits flush or below surface when fully seated

Compatibility

Designed 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.

Installation Notes

Install with a 1/8 inch hex key; ensure the mating shaft or surface is clean and free of burrs before seating the cup point. Power down all equipment and lock out energy sources before servicing any rotating assembly. Follow applicable mechanical safety standards and torque to the fastener manufacturer's specifications for the material and thread class in use.
