5/16-18 x 3/8 Half Dog Point Alloy Steel Socket Set Screw with Nylon Insert helps keep a located component set because the nylon pellet adds prevailing torque after adjustment. Use the half dog style where the receiving hole, slot, or groove is part of the assembly design.

Plant rebuilds use this family when the existing part is a locking half dog point screw, not a cup, cone, flat, or oval point. Check mating feature, hex access, screw length, and marking tolerance.

For replacement work, Cold Headers identifies the requested alloy half dog screw by size, drive, point style, and locking feature. Review insert dimensions, hex key size, and ASME B18.3 before ordering this alloy steel socket set screw.
