3/8-16 x 1 1/4 Half Dog Point Alloy Steel Socket Set Screw with Nylon Insert uses a short cylindrical locating stub to register into a drilled seat, slot, or groove. 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. 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.
