5/16-18 x 3/4 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. Use the half dog style where the receiving hole, slot, or groove is part of the assembly design.

Maintenance repairs often require the same thread, length, point style, and nylon insert already shown on the service record. 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 works with distributors, OEM teams, and maintenance programs that need exact socket set screw configurations. Review insert dimensions, hex key size, and ASME B18.3 before ordering this alloy steel socket set screw.
