Value Collection 601308PR Set Screw 7/16-20 X 5/8 in Cup Point

Product Description

The VALUE COLLECTION 601308PR is a cup point set screw designed for mechanical assemblies where a fastener must apply clamping or locking force without a protruding head. Manufactured from alloy steel, this screw features a 7/16-20 UNF thread and measures 5/8 inches in overall length. The cup point geometry bites into the mating surface to resist rotation and axial movement. Drive is a 7/32-inch hex key socket. It meets ASME/ANSI B18.3 and ASTM F912 standards, confirming dimensional and material compliance. Electricians, HVAC techs, plumbers, and millwrights regularly install set screws of this type when securing pulleys, collars, hubs, and shaft-mounted components.

This set screw is suited for residential and light commercial mechanical applications including motor shaft collars, fan hubs, set-collar assemblies, and similar rotating or fixed shaft components. The 7/16-20 UNF thread is a fine-pitch designation, making it appropriate where controlled engagement and vibration resistance are priorities. The alloy steel construction provides the hardness and shear strength needed for positive holding force in both static and dynamic load conditions.

Key Features

• Cup point geometry bites into mating surface for positive axial and rotational hold
• 7/16-20 UNF fine-pitch thread for precise engagement and vibration resistance
• Alloy steel construction for high hardness and shear strength
• 7/32-inch hex key drive — standard hex key or L-wrench compatible
• Meets ASME/ANSI B18.3 and ASTM F912 dimensional and material standards
• Headless design seats fully below or flush with the work surface

Compatibility

Designed as a standard UNF set screw for use in any threaded bore or assembly specifying a 7/16-20 cup point set screw per ASME/ANSI B18.3.

Installation Notes

Installation requires a 7/32-inch hex key or Allen wrench. Disengage power and lock out any rotating equipment before servicing shaft-mounted components. Do not exceed the torque capacity of the alloy steel fastener by using impact tools or extended-handle wrenches that can strip the hex socket or shear the screw. Follow applicable mechanical codes and equipment manufacturer torque guidelines for the specific assembly.
