1/4-20 x 3/4 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. 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. Use the size callout to match both the thread and installed length.

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.
