5-40 x 7/16 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. For best seating, a shallow drilled dimple can help the point center consistently in the intended position. 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.

Industrial repair work sometimes calls for cone point nylon-insert screws when removal access is from the socket end only.

The locking pellet is installed after the screw body is identified, keeping the insert function separate from the cone point geometry. 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.
