Value Collection 601394BR Set Screw 5/8-11 X 2-3/4 in Cup Point

Product Description

The VALUE COLLECTION 601394BR is a cup point set screw used to secure components such as collars, gears, pulleys, and hubs onto shafts without a protruding head. It is driven by a 5/16-inch hex key and features a cup point tip that bites into the mating surface to resist rotation and axial movement. Manufactured from alloy steel, this fastener provides the hardness and tensile strength required in industrial and mechanical assembly applications. It conforms to ASME/ANSI B18.3 and ASTM F912 standards, making it a reliable choice for engineers, machinists, and maintenance technicians working to spec.

This set screw is suited for use in mechanical assemblies across industrial, manufacturing, and maintenance environments. The 5/8-11 UNC thread and 2-3/4-inch overall length make it appropriate for medium-to-heavy-duty shaft locking applications where a headless fastener profile is required. It is typically installed during initial machine assembly or as a replacement fastener during equipment service and repair.

Key Features

• Cup point tip bites into shaft surface for strong rotational and axial holding
• 5/16-inch hex drive for standard Allen key installation
• Alloy steel construction provides high hardness and tensile strength
• 5/8-11 UNC thread for reliable engagement in standard tapped holes
• Conforms to ASME/ANSI B18.3 and ASTM F912 fastener standards
• Headless design allows flush or below-surface installation

Compatibility

Designed as an OEM-style replacement or direct-use fastener for any mechanical assembly requiring a 5/8-11 UNC cup point set screw with a 2-3/4-inch overall length and 5/16-inch hex drive.

Installation Notes

Installation is performed by machinists or maintenance technicians using a 5/16-inch hex key or Allen driver. Ensure the tapped hole is clean and free of debris before threading in the fastener. Power down and de-energize any equipment before servicing rotating components. Do not exceed the torque rating of the tapped hole material, and confirm thread engagement is sufficient before applying load.
