Value Collection R63006688 Set Screw 1/2-13 X 2 in Cup Point

Product Description

The VALUE COLLECTION R63006688 is a 1/2-13 UNC stainless steel set screw measuring 2 inches in length, featuring a cup point and square drive. It is designed for mechanical assemblies where a fastener must apply holding force against a shaft, hub, or mating surface without a protruding head. The cup point bites into the mating surface to resist rotational and axial movement. Fabricated from Grade 18-8 stainless steel, this fastener offers good corrosion resistance in moderate environments. Machinists, maintenance technicians, and millwrights commonly install these in collars, pulleys, sprockets, and similar power-transmission components.

This set screw is suited for use in both light industrial and mechanical maintenance applications. It is a standard UNC-threaded fastener compatible with through-threaded or tapped-hole assemblies where flush or below-surface seating is required. The square drive requires a square-key driver or wrench, which allows high torque application without cam-out, making it practical for installations that require firm seating of the cup point into a shaft.

Key Features

• Cup point bites into mating shaft surface to resist rotation and axial movement
• Square drive allows high-torque installation with reduced cam-out risk
• Grade 18-8 stainless steel construction provides corrosion resistance in moderate service environments
• Standard 1/2-13 UNC thread for compatibility with common tapped assemblies
• Headless design seats flush or below surface — no protrusion into surrounding clearance envelope

Compatibility

Designed as a standard UNC-threaded set screw for use in tapped holes requiring a 1/2-13 thread, cup point contact, and square drive, typical in mechanical power-transmission assemblies.

Installation Notes

Installation is performed by machinists or mechanical maintenance technicians using a properly sized square-key driver or Allen-style square-drive wrench. Ensure the tapped hole is clean and free of debris before threading the fastener. De-energize and lock out any rotating equipment before servicing shaft-mounted components that use set screws. Do not exceed the thread engagement depth of the tapped hole, as bottoming out under excessive torque can damage threads.
