Value Collection 602442PR Cup Point Set Screw 5/8-11

Product Description

The VALUE COLLECTION 602442PR is a cup point set screw designed for secure, non-permanent fastening in mechanical assemblies where a recessed drive and strong holding force are required. Threaded 5/8-11 UNC with an overall length of 1-3/4 inches, this set screw is manufactured from austenitic Grade A2 stainless steel, providing corrosion resistance suitable for general industrial and trade applications. The 5/16-inch internal hex drive accepts a standard hex key for installation and removal. It meets ASME/ANSI B18.3 and ASTM F880 standards. Machinists, maintenance mechanics, and millwrights install this type of fastener to lock shafts, collars, and hubs in position without protruding hardware.

This set screw is used in shaft collar assemblies, set collar applications, handwheels, pulleys, couplings, and similar mechanical components where the cup point bites into the shaft surface to resist rotational and axial movement. It is appropriate for both light industrial and heavy mechanical environments where stainless steel corrosion resistance is preferred over plain steel. Sold individually per package with a minimum order quantity of 10 pieces.

Key Features

• Cup point geometry bites into shaft material for firm grip and slip resistance
• 5/8-11 UNC thread for compatibility with standard tapped holes in that size range
• 1-3/4 inch overall length provides substantial thread engagement depth
• Austenitic Grade A2 stainless steel resists corrosion in wet or chemically exposed environments
• 5/16-inch hex drive accepts standard hex keys and hex drivers
• Meets ASME/ANSI B18.3 and ASTM F880 fastener standards

Compatibility

Designed as an OEM-style replacement or direct-use set screw for mechanical assemblies requiring a 5/8-11 UNC tapped hole with cup point engagement, per ASME/ANSI B18.3 and ASTM F880 specifications.

Installation Notes

Installation is performed by machinists, millwrights, or maintenance mechanics using a 5/16-inch hex key or T-handle driver. De-energize and lock out any rotating equipment before servicing shaft and collar assemblies. Thread the set screw by hand to confirm engagement before applying torque, and inspect the tapped hole for damage or contamination prior to installation. Follow applicable facility or equipment service standards for set screw torque specifications.
