1/4-28 x 1/2 Cone Point Alloy Steel Socket Set Screw with Nylon Insert is a headless internal-hex fastener for set screw assemblies that need both shaft interlock and thread-level locking action. 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.
Light-drive keyless hub alternatives sometimes use a cone point where the application allows a marked shaft surface.
Cold Headers supports exact-size and hard-to-find cone point nylon-insert sourcing for industrial repair, replacement, and production requirements. Review thread size, length, hex key size, point style, and mating-surface marking tolerance before replacing it with another set screw. The internal hex recess also keeps installation access compact when the screw is recessed in a hub or collar.
