3/8-16 x 7/8 Cone Point Alloy Steel Socket Set Screw with Nylon Insert identifies the exact thread and length for a locking cone point set screw with internal hex installation. This double-action layout combines point seating at the shaft with prevailing torque inside the threaded hole. Use this alloy steel body with the nylon locking pellet where the drawing calls for a mechanical set screw, not a corrosion-focused stainless part.
Common uses include gear and sprocket settings on spotted shafts where rotation control matters after the hub is positioned. Plain alloy steel is not selected for corrosion resistance, so keep parts oiled or choose a stainless request when the environment requires it.
Cold Headers helps industrial buyers keep the point style, drive type, and locking feature aligned with the drawing requirement. Review thread size, length, hex key size, point style, and mating-surface marking tolerance before replacing it with another set screw.
