5/16-18 x 5/16 Half Dog Point Alloy Steel Socket Set Screw with Nylon Insert is the nylon-insert version of a half dog point alloy socket set screw for compact machine assemblies. This point style is chosen when repeatable angular or axial location matters more than a bite mark on an unprepared shaft.

Tooling plates and inspection fixtures can use this set screw where a prepared slot provides the locating path. Check mating feature, hex access, screw length, and marking tolerance.

Since 1962, Cold Headers has supported industrial buyers where a small difference in set screw point geometry changes the fit. Review insert dimensions, hex key size, and ASME B18.3 before ordering this alloy steel socket set screw.
