7/16-20 x 3/8 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.

Maintenance repairs often require the same thread, length, oval point, and locking feature already installed. Plain Oval Point Alloy Socket Set Screws may fit the job when the nylon insert is not required.

The 7/16-20 rows are fine-thread-only in this oval point locking family, so exact thread identification matters. 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.
