5/16-18 x 1/4 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. A shallow prepared groove around the shaft lets the point ride axially while still allowing repositioning. Specify the heat-treated alloy steel body with nylon pellet when the print calls for mechanical set screw hardware, not a stainless substitute.
Machine rebuilds use this family when the service record calls for alloy steel, an oval point, and a nylon insert.
Cold Headers can review non-catalog oval point set screw needs when the application requires a nylon insert. Cold Headers has supplied specialty socket fasteners since 1962, with separate catalog language for each set screw point style. Check thread size, length, socket size, pellet dimensions, groove or seat condition, and surface-marking tolerance before substitution.
