Value Collection 601299PR Set Screw 7/16-14 X 2-1/4 in Cup Point

Product Description

The VALUE COLLECTION 601299PR is a cup point set screw designed for secure, no-projection fastening in mechanical assemblies. It features a 7/16-14 UNC thread in a 2-1/4 inch overall length, with a 7/32 inch internal hex drive for use with a standard hex key or Allen wrench. Made from alloy steel, it delivers the hardness and shear strength required for shaft-to-hub locking, collar retention, and similar industrial fastening tasks. It meets ASME/ANSI B18.3 and ASTM F912 standards. This screw is appropriate for maintenance technicians, millwrights, and mechanical contractors working on rotating equipment and structural assemblies.

Cup point set screws are used across HVAC equipment, pump assemblies, fan shaft collars, and general mechanical drive systems where a headless fastener must seat flush or below the surface. The cup point geometry bites into the mating shaft to resist axial and rotational movement under load. This part is sold in a minimum order quantity of 5 units and is packaged individually per unit.

Key Features

• Cup point geometry bites into shaft surface for strong axial and rotational hold
• 7/16-14 UNC thread for compatibility with standard inch-series tapped holes
• 2-1/4 inch overall length provides deep thread engagement
• 7/32 inch hex drive accepts standard hex keys
• Alloy steel construction for high hardness and shear strength
• Meets ASME/ANSI B18.3 and ASTM F912 fastener standards

Compatibility

Designed as a standard inch-series set screw for use in any 7/16-14 UNC tapped bore requiring a headless cup point fastener in mechanical and industrial applications.

Installation Notes

Installation is performed with a 7/32 inch hex key. Ensure the tapped bore is clean and free of debris before threading the screw. Torque to the value specified by the equipment manufacturer for the shaft diameter and collar material in use. Always de-energize and lock out rotating equipment before servicing shaft collars or drive components.
