1/4-28 x 7/8 Half Dog Point Alloy Steel Socket Set Screw with Nylon Insert is specified when the drawing calls for alloy steel, a half dog point, and a nylon insert in the same screw. Compared with a longer full dog projection, the half dog form can work with a shallower receiving hole and thinner surrounding material.
Control levers pinned to a set angle may call for this point style when the screw locates in a drilled feature. 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.
