5/16-24 x 3/16 Flat Point Alloy Steel Socket Set Screw with Nylon Insert is chosen when a flat point should seat on a shaft flat while the nylon insert resists backing out. The nylon insert works in the female thread, adding prevailing torque while the point handles surface contact. Use the heat-treated alloy steel body with the nylon locking pellet where the application calls for mechanical fastening rather than stainless material.
Machine rebuilds use this family when the service record calls for alloy steel, a flat point, and a nylon insert. Oval Point Alloy Set Screws with Nylon Insert are the better comparison when the contact angle varies across the assembly.
Cold Headers focuses on exact-size socket fastener sourcing for production, repair, and plant maintenance needs. Check thread size, length, socket size, pellet dimensions, shaft-flat condition, and surface-marking tolerance before substitution.
