Value Collection R63642247 Set Screw 3/8-16 X 1 in Cup Point Brass

Product Description

The VALUE COLLECTION R63642247 is a 3/8-16 UNC brass set screw with a cup point and internal hex drive, sized at 1 inch overall length. Set screws of this type are used to secure components onto shafts or inside threaded bores without a protruding head. The cup point digs into the mating surface to resist rotation and axial movement. The hex socket accepts a 3/16-inch hex key for installation. Brass construction provides corrosion resistance and is well suited for applications where galling with steel fasteners is a concern or where non-magnetic, non-sparking properties are required.

This set screw is appropriate for light-duty mechanical assemblies, instrumentation, and fluid system components where brass is the specified fastener material. Common install scenarios include shaft collars, pulleys, knobs, and valve stems in plumbing, HVAC, and general mechanical work. The UNC thread form is the standard inch-series coarse thread, compatible with tapped holes made to ASME B1.1 specifications. Sold individually per package.

Key Features

• Cup point geometry bites into the mating shaft surface to prevent slipping under torque and axial load
• 3/16-inch internal hex drive for standard Allen key installation in confined spaces
• Brass material resists corrosion and is non-sparking, non-magnetic
• 3/8-16 UNC thread for compatibility with standard inch-series tapped holes
• 1-inch overall length suits moderate-depth engagement requirements

Compatibility

Designed for use in any application requiring a 3/8-16 UNC threaded brass cup-point set screw with a 3/16-inch hex drive and 1-inch overall length, including shaft collars, mechanical assemblies, and fluid system components.

Installation Notes

Install using a 3/16-inch hex key; ensure the tapped hole is clean and free of debris before threading. Power down or depressurize any equipment before servicing fasteners on rotating or pressurized components. Brass is a soft material relative to steel — do not over-torque, as thread stripping or cup-point deformation can occur. Follow applicable ASME or OEM torque guidelines for 3/8-16 brass fasteners.
