Value Collection R63642163 Set Screw 3/8-16 X 1/2 in Cup Point

Product Description

The VALUE COLLECTION R63642163 is a cup point set screw designed for mechanical fastening applications where a headless, flush-mount fastener is required. Manufactured from brass, this set screw features a 3/8-16 UNC thread and an overall length of 1/2 inch. The cup point geometry bites into the mating surface to resist rotational and axial movement, making it well-suited for securing shafts, collars, pulleys, and similar components. Installation is performed with a 3/16-inch hex key. Brass construction offers corrosion resistance and is appropriate for use in environments where ferrous fasteners are not suitable.

This set screw is used in light mechanical assemblies, HVAC equipment, plumbing components, and general trade applications where a UNC-threaded headless fastener is needed. The cup point style is one of the most common configurations for shaft-locking duties in residential and light commercial equipment. Technicians working on motor mounts, fan blade hubs, and valve stems will find this size frequently specified. The brass material also makes it a practical choice in applications requiring electrical conductivity or compatibility with non-ferrous assemblies.

Key Features

• 3/8-16 UNC thread for broad compatibility with standard inch-series tapped holes
• Cup point geometry grips mating surfaces to resist shaft movement under load
• Brass construction provides corrosion resistance and non-ferrous compatibility
• Overall length of 1/2 inch suits shallow-boss and thin-collar applications
• Driven with a 3/16-inch hex key, standard in most trade tool sets
• Headless design sits flush or below the surface to eliminate protrusion hazards

Compatibility

Designed as a general-purpose UNC set screw suitable for standard 3/8-16 tapped holes in mechanical assemblies across HVAC, plumbing, and related trade applications.

Installation Notes

Installation requires a 3/16-inch hex key or Allen driver. Ensure the mating shaft or component is free of debris and properly positioned before tightening. Brass is a softer material than steel; avoid over-torquing, which can strip threads or deform the cup point. De-energize or shut down any equipment before performing fastener service on rotating components.
