Value Collection 601504BR Set Screw 7/8-14 X 3 in Cup Point

Product Description

The VALUE COLLECTION 601504BR is a cup point set screw designed for secure fastening in mechanical assemblies where a flush or recessed fastener is required. Sized at 7/8-14 (UNF thread) with a 3-inch overall length, it is driven with a 1/2-inch hex key. Manufactured from alloy steel and rated to ASTM F912, this set screw delivers the hardness and shear resistance needed for holding shafts, collars, pulleys, and gears in position under load. It conforms to ASME/ANSI B18.3 dimensional standards, making it a reliable choice for precision mechanical and industrial applications.

This set screw is suited for use in shaft-to-hub connections, shaft collars, set collar assemblies, couplings, and similar mechanical components found in industrial equipment, HVAC drive assemblies, pump housings, and rotating machinery. The cup point geometry bites into the shaft surface to resist axial and rotational movement. It is appropriate for both new assembly and replacement applications where a UNF 7/8-14 thread form is specified.

Key Features

• Cup point tip bites into shaft material to resist axial and rotational slip
• 7/8-14 UNF thread form for fine-thread engagement and precise clamping
• 3-inch overall length for deep engagement in thick hubs or collars
• Alloy steel construction rated to ASTM F912 for high hardness and load capacity
• 1/2-inch hex drive for standard Allen key or hex bit installation
• Conforms to ASME/ANSI B18.3 dimensional standards

Compatibility

Designed as a direct-fit replacement or new-installation set screw for mechanical assemblies specifying a 7/8-14 UNF cup point set screw with 3-inch overall length and ASME/ANSI B18.3 compliance.

Installation Notes

Installation is typically performed by a millwright, HVAC mechanic, or maintenance technician using a calibrated 1/2-inch hex key or T-handle driver. Ensure the mating shaft and bore are clean and free of debris before seating the screw. De-energize and lock out all rotating equipment before installation or removal per applicable OSHA lockout/tagout procedures. Do not exceed the torque ratings specified for ASTM F912 alloy steel set screws as outlined in the assembly manufacturer's documentation.
