Value Collection 601320PR Set Screw 7/16-20 X 1-3/4 in Cup Point

Product Description

The VALUE COLLECTION 601320PR is a cup point set screw designed for secure, no-protrusion fastening in mechanical assemblies. Threaded 7/16-20 UNF with an overall length of 1-3/4 inches, this screw is driven by a 7/32-inch hex key and terminates in a cup point that bites into a mating surface to resist rotation and axial movement. Manufactured from alloy steel, it delivers the tensile strength required for demanding clamping and locking applications. It conforms to ASME/ANSI B18.3 and ASTM F912 dimensional and performance standards. Machinists, millwrights, and maintenance technicians working with shafts, collars, and hubs are the primary installers.

This set screw is suited for use in shaft-collar assemblies, shaft-to-hub connections, and mechanical locking applications across industrial, HVAC, and general trade settings. The cup point profile is preferred where a positive bite into a shaft surface is needed without requiring a flat or groove on the mating part. It is appropriate for both initial assembly and field replacement work where a 7/16-20 UNF threaded seat is present.

Key Features

• 7/16-20 UNF thread for fine-pitch engagement and precise load control
• Cup point geometry bites into mating surfaces to resist rotation and axial shift
• 7/32-inch hex drive accepts standard hex keys and T-handle wrenches
• Alloy steel construction provides high tensile and torsional strength
• Meets ASME/ANSI B18.3 and ASTM F912 standards for dimensional accuracy and performance
• Overall length of 1-3/4 inches suits deeper threaded bores and collars

Compatibility

Designed as a standard replacement or new-installation set screw for any mechanical assembly with a 7/16-20 UNF threaded seat requiring a cup point, hex-drive fastener.

Installation Notes

Installation is performed by machinists, millwrights, or maintenance technicians using a 7/32-inch hex key or Allen wrench. De-energize and lock out all rotating equipment before installation or removal per applicable OSHA lockout/tagout procedures. Do not exceed the rated torque range for the thread size and material class; consult ASME B18.3 torque tables for reference. Ensure the threaded bore is clean and free of debris before driving the screw to full seating depth.
