3/8-16 x 3/8 Cup Point Alloy Steel Socket Set Screw with Nylon Insert uses heat-treated alloy steel body construction with a nylon pellet in the thread. Use the nylon-insert version when a plain cup point needs added thread friction after seating.

Automation equipment uses these screws in compact hubs, collars, guides, and stops where the headless form saves clearance. Confirm thread size, length, hex key size, cup point geometry, pellet diameter, and pellet location before substituting another set screw.

Use Cold Headers when the requirement is specific: alloy steel body, cup point, internal hex drive, and nylon insert. For wet or washdown service, the related 18-8 stainless cup point set screw with nylon insert is the corrosion-focused catalog choice.
