Value Collection R40322446 Set Screw 3/8-16 Cup Point Ss 18-8

Product Description

The VALUE COLLECTION R40322446 is a cup point set screw designed for secure fastening applications in mechanical assemblies, shaft-to-hub connections, and fixture work. Threaded at 3/8-16 UNC with an overall length of 3/8 inches, this headless fastener is driven with a 3/16-inch hex key. Constructed from 18-8 stainless steel, it resists corrosion in wet or chemically active environments. The cup point digs into the mating surface to resist rotational and axial movement without requiring a separate locking element. Licensed tradespeople and maintenance technicians working on pumps, motors, collars, and similar rotating equipment will find this a dependable fastening solution.

This set screw is suited for light to medium-duty industrial, commercial, and mechanical service applications. Common install scenarios include securing shaft collars, pulleys, sprockets, and knobs to shafts where a flush or recessed fastener is required. The 18-8 stainless steel construction makes it appropriate for environments where carbon steel hardware would corrode, including pool equipment rooms, marine-adjacent installations, and wet mechanical spaces. It is sold individually per unit, with a minimum order quantity of 100 pieces.

Key Features

• Cup point geometry bites into shaft surface for positive rotational and axial hold
• 18-8 stainless steel construction provides corrosion resistance in wet and chemically active environments
• 3/8-16 UNC thread for broad compatibility with standard tapped holes
• 3/16-inch hex drive allows installation with a standard Allen key or hex bit
• Headless design seats flush or below surface for clearance-critical assemblies

Compatibility

Designed as a standard 3/8-16 UNC cup point set screw for use in any tapped hole or threaded component accepting that thread size and pitch.

Installation Notes

Installation requires a 3/16-inch hex key or hex bit driver. De-energize and lock out any equipment before servicing shaft or collar fasteners. Ensure threads in the receiving component are clean and free of debris before driving the screw to seat. Do not exceed the torque capacity of the 18-8 stainless steel material, as stainless fasteners are susceptible to galling if driven too aggressively without lubrication.
