5/16-18 x 1 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. Because the point registers into a prepared feature, check the shaft, hub, or fixture detail before substituting a cup point style.
Timing-critical gear and sprocket setups use this style when a drilled seat helps control position during reassembly. Check mating feature, hex access, screw length, and marking tolerance. The polymer insert changes the service envelope compared with an all-metal screw, so review heat exposure before specifying the locking version.
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.
