5/16-18 x 7/16 Half Dog Point Alloy Steel Socket Set Screw with Nylon Insert is a headless internal-hex fastener for parts that need positive location from a short dog-point stub. Compared with a longer full dog projection, the half dog form can work with a shallower receiving hole and thinner surrounding material.

Couplings that must be assembled in one orientation can use the locating stub to reduce walk and rotation after alignment. Check mating feature, hex access, screw length, and marking tolerance. In-house pellet installation helps support nylon-insert requirements where a plain half dog screw would not meet the print.

Cold Headers helps buyers keep the half dog point requirement visible when similar nylon-insert set screws are easy to confuse. Review insert dimensions, hex key size, and ASME B18.3 before ordering this alloy steel socket set screw.
