1/4-28 x 7/8 Cup Point Alloy Steel Socket Set Screw with Nylon Insert is built for settings where the cup rim and thread friction both matter. That pairing helps the screw resist loosening through friction without replacing the mechanical holding role of the cup point.

Conveyor drives use locking cup point screws in collars, hubs, and adjustment components that are serviced repeatedly. Confirm thread size, length, hex key size, cup point geometry, pellet diameter, and pellet location before substituting another set screw.

Cold Headers supports distributors, maintenance crews, and OEM buyers with carefully identified nylon-insert set screw sizes. For wet or washdown service, the related 18-8 stainless cup point set screw with nylon insert is the corrosion-focused catalog choice.
