4-40 x 1/4 Half Dog Point Alloy Steel Socket Set Screw with Nylon Insert is a heat-treated alloy steel half dog point socket set screw with a nylon insert for prevailing torque. Compared with a longer full dog projection, the half dog form can work with a shallower receiving hole and thinner surrounding material.
Couplings that must be assembled in one orientation can use the locating stub to reduce walk and rotation after alignment. Check mating feature, hex access, screw length, and marking tolerance. Cold Headers installs nylon locking pellets at its Chicago facility for this half dog point locking set screw family.
Cold Headers helps buyers keep the half dog point requirement visible when similar nylon-insert set screws are easy to confuse. Review insert dimensions, hex key size, and ASME B18.3 before ordering this alloy steel socket set screw.
