Value Collection 601329PR Set Screw 1/2-13 X 2-3/4 in Cup Point

Product Description

The VALUE COLLECTION 601329PR is a cup point set screw used to secure components onto shafts, hubs, or other mating surfaces without a protruding head. Sized at 1/2-13 UNC thread with an overall length of 2-3/4 inches, it is driven with a 1/4-inch hex key. The cup point digs into the mating surface to resist axial and rotational movement under load. Made from alloy steel for strength in demanding mechanical assemblies, this fastener meets ASME/ANSI B18.3 and ASTM F912 standards. Machinists, millwrights, and maintenance technicians use this type of fastener in a wide range of industrial and mechanical applications.

This set screw is suited for use in industrial machinery, power transmission components, and general mechanical assemblies where a flush or recessed fastener is required. Typical applications include securing pulleys, gears, collars, and sprockets to shafts. The 1/2-13 UNC thread is a common coarse-thread size found across a broad range of standard mechanical hardware and tooling setups. Sold in a minimum order quantity of 10 pieces.

Key Features

• Cup point geometry bites into mating surface to resist rotation and axial movement
• 1/2-13 UNC coarse thread for broad compatibility with standard tapped holes
• 2-3/4 inch overall length provides deep thread engagement in thick hubs or collars
• Alloy steel construction for high tensile and torsional strength
• 1/4-inch hex drive for standard hex key installation
• Meets ASME/ANSI B18.3 and ASTM F912 fastener standards

Compatibility

Designed as an OEM-style replacement or standard-stock set screw for industrial and mechanical assemblies requiring a 1/2-13 UNC cup point headless fastener with a 1/4-inch hex drive.

Installation Notes

Installation is performed by machinist or maintenance personnel using a 1/4-inch hex key or Allen wrench. De-energize and lock out all rotating or powered equipment before servicing any shaft-mounted components. Ensure the tapped hole is clean and free of debris before threading in the fastener. Do not exceed the rated torque range for the thread size and material as specified in applicable ASME fastener standards.
