Value Collection 409082PR Set Screw 3/8-16 X 4-1/2 in Cup Point

Product Description

The VALUE COLLECTION 409082PR is a cup point set screw designed for mechanical fastening applications where a strong, recessed hold is required. This fully threaded fastener uses a 3/8-16 UNC thread and measures 4-1/2 inches in length under head. It is manufactured from alloy steel to Grade 2 specifications, providing solid tensile strength for general industrial and trade use. The cup point tip bites into the mating surface to resist rotation and axial movement without requiring a protruding head. It is installed using a square drive. Maintenance technicians, millwrights, and mechanical contractors are the typical installers.

This set screw is suited for securing collars, hubs, pulleys, gears, and similar components onto shafts in both residential and light commercial mechanical assemblies. The 3/8-16 UNC thread size is a common standard pitch found in a wide range of machined components and hardware. The 4-1/2 inch length accommodates deeper engagement requirements where shorter set screws are insufficient. Applications span HVAC equipment, pump assemblies, conveyor systems, and general industrial machinery maintenance.

Key Features

• Cup point tip grips mating shaft surface to resist axial and rotational movement
• 3/8-16 UNC thread for broad compatibility with standard inch-fractional hardware
• 4-1/2 inch length provides deep thread engagement for demanding applications
• Alloy steel construction at Grade 2 for reliable tensile performance
• Square drive socket for positive wrench engagement during installation
• Length measured under head per standard fractional inch convention

Compatibility

Designed as a standard inch-fractional set screw for use in any threaded bore or collar accepting a 3/8-16 UNC thread pattern.

Installation Notes

Installation is performed by threading the screw into a pre-tapped 3/8-16 UNC bore using a square drive key or wrench. Power down or de-energize all associated equipment before beginning work. Apply appropriate thread-locking compound if the application involves vibration. Do not over-torque, as alloy steel set screws can seize or deform softer shaft materials.
