Value Collection 601479BR Set Screw 7/8-9 X 2-1/4 in Cup Point

Product Description

The VALUE COLLECTION 601479BR is a cup point set screw designed for secure, non-permanent fastening applications in industrial and mechanical assemblies. Manufactured from alloy steel and graded to ASTM F912, this fastener meets ASME/ANSI B18.3 dimensional standards. It features a 7/8-9 UNC thread and measures 2-1/4 inches in overall length. The 1/2-inch hex drive accepts a standard hex key for installation and removal. Machinists, millwrights, and maintenance technicians use set screws like this to lock shafts, collars, pulleys, and gears in position without a protruding head.

This set screw is suited for use in shaft-to-hub connections, shaft collars, shaft couplings, and similar rotating machinery components. The cup point geometry bites into the mating surface to resist rotational and axial movement under load. Its coarse UNC thread series makes it compatible with standard tapped holes in steel, cast iron, and similar ferrous materials commonly found in industrial equipment and mechanical drive systems.

Key Features

• Cup point geometry provides positive bite into mating shaft or surface for strong holding force
• Alloy steel construction rated to ASTM F912 for high tensile and torsional strength
• 7/8-9 UNC coarse thread for reliable engagement in standard tapped holes
• 1/2-inch hex drive compatible with standard hex keys and Allen wrenches
• Meets ASME/ANSI B18.3 dimensional standards for consistent fitment
• Headless profile allows flush or below-surface installation in counterbored holes

Compatibility

Designed as a standard ASME/ANSI B18.3 cup point set screw for use in any tapped 7/8-9 UNC hole requiring an ASTM F912-grade alloy steel fastener.

Installation Notes

Installation is performed with a 1/2-inch hex key; ensure the key is fully seated before applying torque to avoid rounding the drive socket. De-energize and lock out any rotating machinery before removing or installing set screws on shafts or collars. Inspect the tapped hole for debris or damage before threading in the fastener. Follow applicable industry standards and equipment manufacturer procedures for fastener preload requirements.
