Value Collection 93921 Set Screw 8-32 X 3/8 in Cup Point Ss 50pk

Product Description

The VALUE COLLECTION 93921 is a cup-point set screw sized 8-32 x 3/8 inches, manufactured from Grade 18-8 stainless steel. Set screws are headless fasteners used to secure a component — such as a pulley, collar, or gear — onto a shaft by bearing directly against the shaft surface through a threaded hole. The cup-point geometry bites into the mating surface to resist rotation and axial movement without the need for a nut. Driven with a 5/64-inch hex key, this screw suits applications where corrosion resistance and reliable holding force are required. Sold in a pack of 50.

These screws are used across HVAC, plumbing, electrical, and general mechanical assemblies wherever a set screw is needed to fix a rotating or sliding component in position on a shaft. Common applications include fan blade hubs, motor shaft collars, coupling sleeves, and panel-mounted hardware. Grade 18-8 stainless steel provides adequate corrosion resistance for indoor mechanical environments and light outdoor or damp-location service. The unified coarse thread (UNC) standard ensures compatibility with standard 8-32 tapped holes.

Key Features

• Cup-point tip bites into shaft surface for firm, vibration-resistant hold
• Grade 18-8 stainless steel construction resists corrosion in damp or humid environments
• 8-32 UNC thread mates with standard tapped holes
• 5/64-inch hex drive for precise torque application with a standard hex key or T-handle driver
• 3/8-inch overall length suits shallow-hub and thin-collar installations
• Pack of 50 supports service-kit stocking and multi-unit jobs

Compatibility

Designed as a standard 8-32 UNC cup-point set screw suitable for any tapped hole conforming to the 8-32 unified coarse thread standard.

Installation Notes

Shut down and lock out any rotating equipment before removing or installing set screws. Use a correctly sized 5/64-inch hex key to avoid rounding the drive socket. Ensure the mating tapped hole is clean and free of debris before threading the screw in. Do not exceed hand-tight seating confirmed by feel; over-driving a small-diameter set screw without calibrated tooling risks stripping the threads or fracturing the fastener.
