3/8-16 x 3/8 Flat Point Alloy Steel Socket Set Screw with Nylon Insert is the nylon-insert version of a flat point socket set screw for compact industrial assemblies. The internal hex drive keeps the screw headless and accessible in collars, hubs, and compact machine details. Use the heat-treated alloy steel body with the nylon locking pellet where the application calls for mechanical fastening rather than stainless material.

Handle and control retention often benefits from a headless screw that can be serviced from the socket end. Plain Flat Point Alloy Socket Set Screws may fit the job when the nylon insert is not required.

Cold Headers installs nylon locking pellets in-house at its Chicago facility for this flat point set screw family. The catalog keeps this family separate from plain flat point screws so the nylon insert requirement remains visible. Check thread size, length, socket size, pellet dimensions, shaft-flat condition, and surface-marking tolerance before substitution.
