Value Collection NT-440-187-SS Set Screw 4-40 X 3/16 in Ss

Product Description

The VALUE COLLECTION NT-440-187-SS is a 4-40 UNC hex-drive set screw with a nylon soft tip point, manufactured from Grade 18-8 stainless steel. At 3/16 inches in length, this fully threaded fastener is designed to secure a component within or against another part without a protruding head. The nylon tip protects the mating surface from marring or galling during tightening, making it well suited for applications where surface finish or component integrity must be maintained. Grade 18-8 stainless steel provides corrosion resistance in moderate environments. This fastener is installed by machinists, maintenance technicians, and trade professionals working with mechanical assemblies.

This set screw is used in light mechanical assemblies, shaft-to-hub connections, and positioning applications where a non-damaging tip is required. The 4-40 thread size is common in small-scale mechanical and electromechanical assemblies found in HVAC controls, electrical enclosures, and precision equipment. The hex drive accepts a standard hex key or Allen wrench. It is sold individually per package with a minimum order quantity of 10 units.

Key Features

• Nylon soft tip protects mating surfaces from marring or galling under load
• Grade 18-8 stainless steel construction for corrosion resistance
• 4-40 UNC thread standard for compatibility with common small-fastener tapped holes
• Hex drive accepts standard hex keys for straightforward installation and removal
• Fully threaded along the 3/16-inch length for maximum thread engagement in shallow bosses

Compatibility

Designed as a standard 4-40 UNC hex-drive soft-tip set screw suitable for light mechanical assemblies requiring a non-marring fastener in a 4-40 tapped hole.

Installation Notes

Installation is performed with a hex key sized to the internal hex drive; do not use an oversized or worn key, as this can strip the drive socket. Ensure the tapped hole is clean and free of debris before threading in the screw. Avoid over-torquing, as the nylon tip and small thread size limit the applied torque capacity. Follow applicable mechanical assembly standards and any equipment manufacturer torque guidelines when specified.
