Value Collection R63006062 Set Screw 1/2-13 X 1 in

Product Description

The VALUE COLLECTION R63006062 is a 1/2-13 x 1 inch cup point set screw manufactured from Grade 18-8 stainless steel. Set screws are fully threaded fasteners with no head, designed to secure a component — such as a collar, pulley, or gear — against or onto a shaft by bearing directly into the mating surface. The cup point geometry creates a small circular bite into the shaft, providing strong holding force while allowing future removal without permanent shaft damage. The square drive requires a square-key wrench for installation. This fastener is a standard choice in mechanical assemblies across HVAC, plumbing, electrical, and general industrial applications.

This set screw is suited for use in residential and light commercial mechanical assemblies where corrosion resistance is a priority. Grade 18-8 stainless steel performs well in humid, wet, or mildly corrosive environments, making it a reliable choice for equipment rooms, rooftop units, and process piping supports. It follows the UNC (Unified National Coarse) thread standard and is measured by length under head, consistent with standard set screw conventions. Technicians and millwrights installing shaft collars, couplings, fan hubs, or similar components will find this a direct-fit fastener in that thread class.

Key Features

• 1/2-13 UNC thread for broad compatibility with standard inch-series tapped holes
• Cup point geometry delivers firm shaft engagement and allows non-destructive removal
• Grade 18-8 stainless steel construction resists corrosion in wet and humid service environments
• Square drive design provides positive torque transfer during installation and removal
• 1 inch length under head suits medium-depth engagement applications

Compatibility

Designed as a standard UNC inch-series set screw for use in any 1/2-13 tapped hole requiring a cup point, square drive fastener in stainless steel.

Installation Notes

Installation is performed with a square-key (square drive) wrench sized to match the fastener drive. Always de-energize and lock out equipment before servicing any assembly that includes set screws. Verify the tapped hole is clean and free of debris before threading in the fastener. Do not exceed the torque capacity of the stainless steel alloy, as 18-8 stainless is susceptible to galling — applying an anti-galling lubricant to the threads prior to installation is a common field practice.
