5/8-11 x 3/8 Flat Point Alloy Steel Socket Set Screw with Nylon Insert is a heat-treated alloy steel flat point socket set screw with a nylon insert for prevailing torque. 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.
Cold Headers can review non-catalog flat point set screw needs when the application requires a nylon insert. Large 5/8 flat point locking set screws are not always easy to source through general-line channels. The catalog keeps this family separate from plain flat point screws so the nylon insert requirement remains visible. Check size, socket, pellet dimensions, and surface-marking tolerance before substitution.
