Value Collection 601373PR Set Screw 9/16-12x1 Cup Point

Product Description

The VALUE COLLECTION 601373PR is a cup point set screw designed for mechanical assemblies where a fastener must apply holding force without a protruding head. Manufactured from alloy steel to ASTM F912 and dimensioned to ASME/ANSI B18.3, this screw features a 9/16-12 UNC thread and a 1-inch overall length. Drive engagement is achieved with a 1/4-inch hex key. The cup point geometry bites into the mating shaft surface to resist rotation and axial movement. Machinists, millwrights, and maintenance technicians routinely install set screws of this type when securing pulleys, collars, gears, and hubs to shafts.

This set screw is suited for use in power transmission, conveyor, and general industrial machine assembly applications. It is a fractional-inch, UNC-threaded fastener, making it appropriate for equipment built to inch-based standards. The cup point is a general-purpose point style that works across a wide range of shaft materials and surface hardness levels. Sold individually per package with a minimum order quantity of 5 pieces.

Key Features

• Cup point geometry bites into shaft surface for reliable holding force without a protruding head
• 9/16-12 UNC thread with 1-inch overall length for deep thread engagement
• Alloy steel construction meets ASTM F912 material grade requirements
• 1/4-inch hex drive conforms to ASME/ANSI B18.3 socket set screw standard
• Fractional-inch measurement type for compatibility with inch-standard equipment

Compatibility

Designed as an OEM-style replacement or service fastener for mechanical assemblies requiring a 9/16-12 UNC headless cup point set screw conforming to ASME/ANSI B18.3 and ASTM F912.

Installation Notes

Installation is performed with a 1/4-inch hex key; ensure the key is fully seated before applying torque to avoid rounding the drive socket. Power down and de-energize all rotating equipment before servicing any shaft-mounted component. Clean the threaded bore and shaft surface of grease or debris prior to installation to ensure proper seating of the cup point. Follow applicable machinery safety standards and your facility lockout/tagout procedures throughout service.
