Value Collection 601483BR Set Screw 7/8-9 X 4 in Cup Point

Product Description

The VALUE COLLECTION 601483BR is a cup point set screw designed for mechanical assemblies where a fastener must bear against a shaft or surface without protruding beyond the workpiece. Sized at 7/8-9 thread pitch and 4 inches overall length, it is driven with a 1/2-inch hex key. Manufactured from alloy steel to ASTM F912 and ASME/ANSI B18.3 standards, this set screw delivers reliable holding force in high-stress applications. The cup point geometry bites into the mating surface to resist rotational and axial movement. Machinists, millwrights, and maintenance technicians are the typical installers.

This set screw is suited for use in power transmission components such as shaft collars, shaft couplings, pulleys, and sprockets where a flush or sub-flush fastener is required. The 7/8-9 UNC thread and 4-inch length make it appropriate for heavy-duty industrial equipment with larger shaft diameters. It is a fractional inch fastener and fits standard UNC tapped holes of the corresponding size.

Key Features

• 7/8-9 UNC thread provides strong engagement in standard fractional inch tapped holes
• 4-inch overall length accommodates deep tapped bores in thick collars or hubs
• Cup point geometry digs into shaft surface to resist axial and rotational slip
• Alloy steel construction rated to ASTM F912 for high-strength applications
• ASME/ANSI B18.3 compliant for dimensional consistency
• 1/2-inch hex drive accepts standard hex keys and Allen sockets

Compatibility

Designed as an OEM-style replacement or direct-use fastener for mechanical assemblies requiring a 7/8-9 UNC cup point set screw with a 4-inch length and 1/2-inch hex drive.

Installation Notes

Installation is typically performed by machinists or millwrights using a calibrated hex key or Allen socket driver. Ensure the tapped hole is clean and free of debris before threading in the fastener. De-energize and lock out any rotating equipment before servicing shaft-mounted components. Do not exceed the torque capacity of the alloy steel fastener by using an improperly sized driver or extension.
