5-40 x 1/2 Cone Point Alloy Steel Socket Set Screw with Nylon Insert is built for applications where a pointed set screw should center in a prepared spot and stay loaded by pellet friction. The cone point is selected for mechanical interlock because the tapered tip seats into a spot or dimple instead of only pressing on the surface. 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.
Pulley hubs and sheaves often use cone points when a prepared seat is available and the setting should not creep in service.
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.
