Value Collection 601293PR Set Screw 3/8-24 X 2-1/4 in Cup Point

Product Description

The VALUE COLLECTION 601293PR is a cup point set screw designed for secure, no-protrusion fastening in mechanical assemblies. Threaded 3/8-24 UNF with an overall length of 2-1/4 inches, it is driven by a 3/16 inch hex key and terminates in a cup point that bites into the mating surface to resist rotation and axial movement. Manufactured from alloy steel, this fastener meets ASME/ANSI B18.3 and ASTM F912 standards. It is installed by machinists, maintenance technicians, and mechanical contractors wherever a flush or recessed fastening solution is required.

Cup point set screws are used across a wide range of industrial and mechanical applications including shaft-to-hub connections, collar and gear retention, and fixture clamping. The 3/8-24 UNF thread pitch suits fine-thread tapped holes in steel, cast iron, and aluminum components. The 2-1/4 inch length accommodates deeper engagement requirements where standard shorter screws are insufficient. This fastener is appropriate for both light-duty and moderate-load applications in manufacturing, maintenance, and field service environments.

Key Features

• 3/8-24 UNF thread for fine-pitch tapped hole engagement
• 2-1/4 inch overall length for deep-reach fastening applications
• Cup point geometry bites into mating surface to resist loosening under vibration
• 3/16 inch hex drive accepts standard hex keys and Allen drivers
• Alloy steel construction for strength and hardness in mechanical service
• Meets ASME/ANSI B18.3 and ASTM F912 fastener standards

Compatibility

Designed as a standard replacement or new-installation set screw for any mechanical assembly with a 3/8-24 UNF tapped blind hole requiring a cup point fastener per ASME/ANSI B18.3.

Installation Notes

Installation is performed by machinists or mechanical technicians using a 3/16 inch hex key or Allen driver. De-energize and lock out all rotating or powered equipment before installing or removing set screws. Ensure the tapped hole is clean and free of debris before threading the fastener. Do not exceed the torque capacity of the alloy steel fastener or the tapped material.
