1/2-13 x 3/8 Flat Point Alloy Steel Socket Set Screw with Nylon Insert is specified when friction clamping and thread-level locking are both required in a headless fastener. 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.
Pelletized flat point screws keep the thread-locking feature separate from the non-penetrating point geometry. For replacement work, Cold Headers helps keep thread, length, material story, point style, and insert function aligned. Check thread size, length, socket size, pellet dimensions, shaft-flat condition, and surface-marking tolerance before substitution.
