1/4-28 x 5/16 Half Dog Point Alloy Steel Socket Set Screw with Nylon Insert uses half dog point geometry for registered alignment in equipment that cannot rely on a plain shaft bite. This point style is chosen when repeatable angular or axial location matters more than a bite mark on an unprepared shaft.
Keyless locating on light-duty shafts can use the half dog point where a positive register is preferred over aggressive surface bite. Check mating feature, hex access, screw length, and marking tolerance. This size is a hard-to-find nylon-insert half dog option, so keep the exact thread and length together when requesting a 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.
