5/16-18 x 5/8 Half Dog Point Alloy Steel Socket Set Screw with Nylon Insert fits applications where the screw must locate into a drilled feature and hold its setting after installation. This point style is chosen when repeatable angular or axial location matters more than a bite mark on an unprepared shaft.

OEM assemblies with drilled locating seats use these screws to make service replacement more repeatable. Check mating feature, hex access, screw length, and marking tolerance. If exposure requires stainless material, a stainless half dog nylon-insert version is a non-catalog request Cold Headers can quote.

When a print calls for a locating stub plus nylon thread drag, Cold Headers can quote the matching catalog item by exact size. Review insert dimensions, hex key size, and ASME B18.3 before ordering this alloy steel socket set screw.
