5/16-18 x 3/16 Oval Point Alloy Steel Socket Set Screw with Nylon Insert is specified when tangent contact and thread-level locking are both required in a headless fastener. Use this style where the assembly needs rounded contact and a separate thread-locking feature. Specify the heat-treated alloy steel body with nylon pellet when the print calls for mechanical set screw hardware, not a stainless substitute.
Automation machinery can use these screws in compact collars, guide blocks, stops, and control components.
Cold Headers can quote the requested oval point nylon-insert item without steering the request toward a biting point style. Check thread size, length, socket size, pellet dimensions, groove or seat condition, and surface-marking tolerance before substitution. Socket-key access remains compact when the screw sits below the outside surface of a collar or hub.
