Value Collection 409112BR Set Screw 5/8-11x1 Cup Point

Product Description

The VALUE COLLECTION 409112BR is a cup point set screw designed for mechanical fastening applications where a secure, non-projecting hold is required. Manufactured from Grade 2 alloy steel, this screw features a 5/8-11 UNC thread and a 1-inch length measured under the head. The cup point tip bites into the mating surface to resist rotation and axial movement without the need for a through-hole. Driven with a square drive tool, it is well-suited for use in collars, hubs, pulleys, and shaft assemblies across industrial and mechanical maintenance settings.

This set screw is appropriate for use in light to medium-duty mechanical assemblies where a cup point is specified to grip shafts or mating components. It is commonly installed by maintenance technicians and millwrights in manufacturing facilities, machine shops, and general industrial environments. The 5/8-11 UNC thread is a standard coarse-thread designation, making this screw a straightforward replacement or stocking fastener for field and shop use. Sold individually with a minimum order quantity of 10 pieces.

Key Features

• Cup point geometry bites into mating surfaces to prevent rotation and axial movement
• 5/8-11 UNC coarse thread for compatibility with standard tapped holes
• Grade 2 alloy steel construction provides adequate strength for general mechanical service
• Square drive socket for positive torque engagement during installation
• 1-inch length measured under head suits medium-depth engagement requirements
• Non-projecting design eliminates external protrusion for flush or recessed installations

Compatibility

Designed as a standard 5/8-11 UNC cup point set screw suitable for collars, hubs, pulleys, and other mechanical components with a matching tapped set-screw hole.

Installation Notes

Installation requires a square drive bit or key sized to fit the socket. Always ensure the mating component is properly aligned and the tapped hole is clean and free of debris before driving the screw. Tighten to the assembly specification for the application — do not over-torque alloy steel set screws, as this can strip threads or damage softer shaft materials. Shut down and lock out any rotating equipment before servicing shaft collars or pulleys per applicable OSHA lockout/tagout procedures.
