4-40 x 1/2 Oval Point Alloy Steel Socket Set Screw with Nylon Insert supports repeated adjustment because the radiused tip can ride against the mating surface as settings change. The internal hex drive keeps the screw headless and accessible in collars, hubs, handles, and compact control parts. Specify the heat-treated alloy steel body with nylon pellet when the print calls for mechanical set screw hardware, not a stainless substitute.
Typical uses include adjustment collars that are repositioned between production runs without changing the basic hardware. Flat Point Alloy Set Screws with Nylon Insert are the comparison when a flat seat and minimal marking are the priority.
Cold Headers focuses on exact-size socket fastener sourcing for production cells, repairs, and plant maintenance programs. Check thread size, length, socket size, pellet dimensions, groove or seat condition, and surface-marking tolerance before substitution.
