Value Collection 409109PR Set Screw 1/2-13 X 6 in Cup Point

Product Description

The VALUE COLLECTION 409109PR is a 1/2-13 UNC cup point set screw measuring 6 inches in length, manufactured from Grade 2 alloy steel. Set screws of this type are fully threaded fasteners with no head — they seat flush or below the surface of the mating part, using a square drive for installation and removal. The cup point geometry bites into the shaft or surface being secured, providing strong resistance to rotational and axial movement. This fastener is sized for heavy-duty industrial and mechanical applications where a standard-length set screw is insufficient.

This set screw is suited for use in shaft collars, hubs, pulleys, gears, and mechanical assemblies requiring a secure, recessed fastening point. The 1/2-13 UNC thread and 6-inch length make it appropriate for deep-threaded bores in large-diameter components. Typical installers include millwrights, maintenance mechanics, and industrial assembly technicians working on rotating equipment, conveyor systems, or structural mechanical connections.

Key Features

• 1/2-13 UNC thread for broad compatibility with standard fractional inch tapped holes
• Cup point geometry bites into mating surface for strong grip against rotation and axial shift
• Square drive for high torque transmission during installation
• Grade 2 alloy steel construction provides solid mechanical strength for industrial use
• 6-inch length accommodates deep-threaded bores in large mechanical components
• Length measured under head (fully threaded body, no head)

Compatibility

Designed as a standard 1/2-13 UNC cup point set screw for use in any tapped hole conforming to UNC fractional inch thread standards at this diameter and pitch.

Installation Notes

Installation requires a square drive bit or key sized to the drive recess. Ensure the threaded bore is clean and free of debris before threading the screw in. De-energize and lock out any rotating equipment before servicing fasteners on shaft assemblies. Follow applicable ASME or industrial fastener torque guidelines for the specific application and mating material.
