5/16-18 x 1 Oval Point Alloy Steel Socket Set Screw with Nylon Insert is a compact locking set screw for parts that need internal hex access and a rounded contact point. 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.

Fine-thread 7/16-20 and 5/8-18 rows help match uncommon oval point locking requirements that are easy to mis-source.

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.
