Value Collection 409106PS Set Screw 1/2-13x4 Cup Point Grade 2

Product Description

The VALUE COLLECTION 409106PS is a 1/2-13 UNC cup point set screw machined from Grade 2 steel with a bright, uncoated finish. At 4 inches in length, this fully threaded fastener is designed to secure components — such as collars, hubs, pulleys, and sprockets — against rotational or axial movement on a shaft. The square drive socket accepts a square-key wrench for high-torque installation in confined spaces. The cup point geometry bites into the mating surface to resist loosening under vibration and load. This is an industrial-grade mechanical fastener suited for maintenance, manufacturing, and assembly applications.

Cup point set screws in the 1/2-13 thread size are commonly used in power transmission assemblies, machine tool setups, and general industrial maintenance. The 4-inch length accommodates deeper engagement requirements where standard-length set screws fall short. This fastener is appropriate for both light production runs and field repair work in manufacturing plants, fabrication shops, and mechanical maintenance environments. The bright uncoated finish is suitable for interior or protected applications where corrosion resistance is not a primary requirement.

Key Features

• 1/2-13 UNC thread for broad compatibility with standard tapped holes
• Cup point geometry grips shaft surface to resist slippage under load and vibration
• Square drive socket allows high-torque installation with a square-key wrench
• 4-inch length measured under head for deep-engagement applications
• Grade 2 steel construction provides adequate strength for general mechanical fastening
• Bright, uncoated finish — no coating buildup to affect thread fit

Compatibility

Designed as a standard 1/2-13 UNC cup point set screw suitable for use in any tapped hole conforming to 1/2-13 Unified National Coarse thread specifications.

Installation Notes

Installation is performed by machinists, millwrights, and mechanical maintenance technicians using a properly sized square-key wrench. Ensure the mating tapped hole is clean and free of debris before threading the screw. De-energize and lock out any rotating equipment before installing or removing set screws in power transmission components. Do not exceed the torque capacity of the Grade 2 steel — use a torque wrench where specifications are provided by the equipment manufacturer.
