Value Collection 409076PR Cup Point Set Screw 3/8-16x2

Product Description

The VALUE COLLECTION 409076PR is a 3/8-16 cup point set screw designed for secure, positive locking in threaded assemblies. At 2 inches in length, it provides deep thread engagement suitable for demanding mechanical connections. The cup point tip bites into the mating surface to resist rotation and axial movement. Driven by a square drive, it delivers high torque transfer with reduced risk of cam-out. Manufactured from Grade 2 steel with a bright uncoated finish, this fastener is suited for general-purpose industrial and mechanical applications. Installation is performed by maintenance technicians, machinists, and millwrights working with shafts, collars, and similar assemblies.

This set screw is commonly used to lock shaft collars, pulleys, gears, and sprockets onto rotating shafts. The UNC 3/8-16 thread standard makes it compatible with standard inch-series tapped holes found across a wide range of mechanical equipment. The 2-inch length accommodates applications requiring extended thread engagement or deeper locking depth. The cup point configuration is a standard industrial choice where a permanent or semi-permanent positive lock into soft or hardened shaft material is required.

Key Features

• Cup point tip provides positive bite into shaft material for reliable axial and rotational locking
• Square drive allows high-torque installation with minimal cam-out
• 3/8-16 UNC thread for compatibility with standard inch-series tapped holes
• 2-inch length under head for deep thread engagement
• Grade 2 steel construction suitable for general-purpose mechanical applications
• Bright uncoated finish for use in dry or protected indoor environments

Compatibility

Designed as a general-purpose replacement or replacement stock fastener for any assembly requiring a 3/8-16 UNC cup point set screw with a 2-inch length under head and square drive.

Installation Notes

Installation requires a square drive bit or key of the appropriate size matched to the fastener drive. Power down and de-energize any rotating equipment fully before servicing shaft assemblies. Use a thread-locking compound if vibration resistance beyond the cup point engagement is required. Follow applicable ASME or equipment manufacturer torque guidance for the assembly.
