Value Collection 601456BR Set Screw 3/4-16 X 1 in Cup Point

Product Description

The VALUE COLLECTION 601456BR is a cup point set screw designed for secure shaft-to-hub and collar-to-shaft fastening in mechanical assemblies. Manufactured from alloy steel, this fastener measures 3/4-16 (UNF thread) by 1 inch in overall length and is driven with a 3/8-inch hex key. The cup point tip bites into the mating surface to resist rotation and axial movement under load. It meets ASME/ANSI B18.3 and ASTM F912 standards, making it suitable for applications where dimensional and material traceability is required. Machinists, millwrights, and mechanical contractors commonly specify this fastener in production and maintenance work.

This set screw is used in industrial and commercial mechanical assemblies where a headless, flush-mount fastener is needed. Typical applications include securing collars, pulleys, gears, and sprockets to shafts. The cup point geometry provides a positive grip on both hardened and unhardened shaft surfaces. It is appropriate for use in HVAC equipment drives, pump assemblies, conveyor systems, and general machinery maintenance where a 3/4-16 UNF threaded socket is present.

Key Features

• Cup point tip provides positive bite into mating shaft surface to resist rotation and axial displacement
• 3/4-16 UNF thread for use in fine-thread tapped holes
• 1-inch overall length suits medium-depth engagement applications
• 3/8-inch hex drive accommodates standard hex keys and T-handle drivers
• Alloy steel construction offers high tensile and torsional strength
• Meets ASME/ANSI B18.3 and ASTM F912 dimensional and material standards

Compatibility

Designed as a standard-specification replacement or stock fastener for any mechanical assembly requiring a 3/4-16 UNF cup point set screw with a 3/8-inch hex drive, conforming to ASME/ANSI B18.3 and ASTM F912.

Installation Notes

Installation is performed by machinists, millwrights, or maintenance technicians using a 3/8-inch hex key or T-handle driver. De-energize and lock out all rotating equipment before servicing any shaft or hub assembly. Thread the screw into the tapped socket by hand first to confirm proper thread engagement before applying drive torque, and inspect the mating shaft surface for damage or contamination that could affect grip. Follow applicable facility maintenance procedures and equipment manufacturer guidelines during assembly.
