Value Collection 601301PR Set Screw 7/16-14 X 2-1/2 in Cup Point

Product Description

The VALUE COLLECTION 601301PR is a cup point set screw designed for mechanical assemblies where a threaded fastener must apply clamping or locking force without a protruding head. The screw features a 7/16-14 UNC thread and an overall length of 2-1/2 inches. Drive engagement is through a 7/32-inch hex socket. The cup point geometry bites into the mating surface to resist rotation and axial movement, making it well suited for shaft collars, pulleys, and similar components. Licensed machinists, millwrights, and maintenance mechanics typically install these fasteners using a standard hex key or Allen driver.

This set screw is manufactured from alloy steel, which provides greater hardness and tensile strength compared to plain carbon steel grades, supporting use in moderate- to high-load mechanical assemblies. It conforms to ASME/ANSI B18.3 and ASTM F912 dimensional and mechanical standards, covering socket set screws in fractional inch sizes. Typical applications include shaft-to-hub retention, adjustable stop collars, and machine tool fixtures in both industrial and light manufacturing environments.

Key Features

• Cup point geometry bites into mating surfaces to resist axial and rotational movement
• 7/32-inch hex socket drive for use with standard Allen keys or hex drivers
• 7/16-14 UNC thread for broad compatibility with standard tapped holes
• Alloy steel construction provides elevated hardness and load capacity versus carbon steel
• Meets ASME/ANSI B18.3 and ASTM F912 standards for dimensional and mechanical conformance
• Headless design sits flush or below surface to eliminate protrusion in rotating assemblies

Compatibility

Designed as a standard fractional-inch socket set screw for use in any application with a 7/16-14 UNC tapped hole requiring a cup point, headless fastener per ASME/ANSI B18.3.

Installation Notes

Installation is performed with a 7/32-inch hex key or T-handle driver. De-energize and lock out any equipment before accessing shaft or collar fasteners. Do not exceed the torque capacity of the alloy steel material by using extended-handle drivers or breaker bars on small-diameter sockets. Ensure the mating shaft or surface is clean and free of burrs before seating the cup point to achieve proper holding force.
