5/16-24 x 5/8 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.

Grooved-shaft assemblies use the oval point to ride the groove while helping retain axial position.

Cold Headers can review non-catalog oval point set screw needs when the application requires a nylon insert. 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.
