Value Collection R63006449 Set Screw 3/8-16 Cup Point 18-8

Product Description

The VALUE COLLECTION R63006449 is a 3/8-16 x 1-1/2 inch cup point set screw made from Grade 18-8 stainless steel. It features a square drive and a unified national coarse (UNC) thread form. The cup point tip bites into the mating shaft or surface to resist rotation and axial movement. Length is measured under the head. This fastener is used by maintenance technicians, millwrights, and mechanical contractors in applications where corrosion resistance and secure shaft locking are required.

This set screw is suited for light-duty to medium-duty shaft collars, shaft couplings, pulleys, sprockets, and similar mechanical assemblies in industrial, HVAC, and general maintenance environments. The 18-8 stainless steel construction makes it appropriate for use in wet, humid, or mildly corrosive conditions where carbon steel fasteners would corrode prematurely. The square drive requires a square-bit driver or key for installation.

Key Features

• Cup point geometry provides reliable shaft engagement and resistance to rotation
• Grade 18-8 stainless steel construction resists corrosion in wet and humid environments
• 3/8-16 UNC thread for broad compatibility with standard inch-series tapped components
• Square drive allows high torque application without drive-tip strip-out
• Length measured under head: 1-1/2 inches

Compatibility

Designed as a standard 3/8-16 UNC cup point set screw for use in any tapped bore or collar accepting that thread size and drive type.

Installation Notes

Installation is performed by threading technicians or maintenance mechanics using a square-bit driver or appropriate key. Ensure the tapped bore is clean and free of debris before installation. Power down and de-energize rotating equipment completely before tightening or removing set screws on shaft-mounted components. Do not exceed the rated drive engagement or overtorque, as this can deform the cup point or damage the mating shaft surface.
