Value Collection 409084PR Set Screw 7/16-14 X 3/4 in Cup Point

Product Description

The VALUE COLLECTION 409084PR is a cup point set screw designed for secure, no-fastener-head clamping applications in mechanical assemblies. Manufactured from alloy steel to Grade 2 specification, this fastener features a square drive and a cup point tip that bites into the mating surface to resist rotational and axial movement. The 7/16-14 UNC thread and 3/4-inch body length make it a standard choice for shaft collars, pulleys, gears, and similar components found in HVAC equipment, pumps, and general mechanical systems. Plumbers, millwrights, HVAC technicians, and general maintenance trades install these in both new assemblies and field repairs.

This set screw is suited for residential and light commercial mechanical assemblies where a recessed, flush-mount fastener is required. Common applications include securing rotating components to shafts, locking collars in place, and adjusting the position of hubs or sprockets without protruding hardware. The cup point provides a positive bite on soft and hardened shaft materials alike, making it versatile across a range of mechanical installations.

Key Features

• Cup point tip bites into mating surface for positive, slip-resistant hold
• Square drive for reliable torque transfer with standard square-drive bits or keys
• 7/16-14 UNC thread standard ensures broad compatibility with tapped holes
• Alloy steel construction provides strength suitable for mechanical clamping loads
• Grade 2 material designation for consistent mechanical property standards
• Length measured under head at 3/4 inch, flush or below surface when fully seated

Compatibility

Designed as a standard UNC set screw for use in any tapped hole meeting the 7/16-14 thread specification, including shaft collars, hubs, pulleys, gears, and mechanical brackets across a wide range of industrial and trade applications.

Installation Notes

Installation is performed with a square-drive bit or key sized to the fastener drive. Confirm the tapped hole is clean and free of debris before threading the screw in. De-energize or lock out any machinery before servicing components secured by set screws. Do not exceed the rated torque range for the drive size, and avoid reusing set screws that show deformation at the drive or point.
