1/4-20 x 7/8 Half Dog Point Alloy Steel Socket Set Screw with Nylon Insert identifies the exact thread and length for a half dog point alloy set screw with thread-level locking. Compared with a longer full dog projection, the half dog form can work with a shallower receiving hole and thinner surrounding material.

Repair assemblies with thin hub walls can favor the half dog form when a shallower receiving feature is available. Check mating feature, hex access, screw length, and marking tolerance. The nylon pellet is added to the thread path so the locking action is separate from the short locating stub.

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.
