Value Collection R63263026 Set Screw 3/8-24 X 1/4 in Cup Point

Product Description

The VALUE COLLECTION R63263026 is a 3/8-24 x 1/4-inch cup point set screw manufactured from Grade 18-8 stainless steel. It is driven with a 3/16-inch hex key and features a cup point tip that bites into the mating shaft to resist rotation and axial movement. The UNF thread standard and stainless steel construction make this fastener appropriate for applications where corrosion resistance is required. Plumbers, HVAC technicians, electricians, and mechanical contractors use set screws like this to secure collars, sprockets, pulleys, and hubs to shafts in both new construction and service work.

This set screw is suited for light-duty to medium-duty shaft-locking applications in residential and commercial mechanical systems. The cup point geometry creates a positive indent in soft to medium-hardness shaft materials, providing reliable hold without the need for adhesives. The 3/8-24 UNF thread pitch offers finer thread engagement compared to UNC equivalents, making it a common choice in precision mechanical assemblies and trade equipment where controlled clamping force is needed.

Key Features

• Thread size 3/8-24 UNF for fine-thread engagement and controlled clamping
• 1/4-inch overall length suits shallow boss and hub applications
• Cup point tip bites into shaft surface to resist rotation and axial shift
• Grade 18-8 stainless steel provides corrosion resistance in wet or humid environments
• 3/16-inch hex drive is compatible with standard hex keys and T-handle wrenches

Compatibility

Designed as a standard UNF set screw for use in any 3/8-24 threaded bore requiring a cup point fastener. Verify thread pitch and boss depth before installation.

Installation Notes

Installation is performed with a 3/16-inch hex key or Allen wrench. Before installing or removing set screws on mechanical assemblies, de-energize the equipment and lock out or tag out per applicable safety procedures. Do not overtighten, as excessive torque can strip the hex socket or deform the shaft surface. Follow equipment manufacturer torque guidelines where specified.
