4-40 x 1/4 Cone Point Alloy Steel Socket Set Screw with Nylon Insert is a heat-treated alloy steel cone point socket set screw with a nylon insert for thread drag after seating. 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.
Cam plates and eccentric adjustments may specify cone point hardware where the final position must remain indexed. For a general-purpose point with a broader size range, review Cup Point Alloy Set Screws with Nylon Insert.
Cold Headers installs nylon locking pellets in-house at its Chicago facility for this cone point set screw family. 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.
