1/4-20 x 5/8 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. This point style is chosen when repeatable angular or axial location matters more than a bite mark on an unprepared shaft.

OEM assemblies with drilled locating seats use these screws to make service replacement more repeatable. Check mating feature, hex access, screw length, and marking tolerance. It also separates the locating requirement from ordinary cup-point grip.

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.
