5-40 x 5/8 Cone Point Alloy Steel Socket Set Screw with Nylon Insert provides a tapered conical point for deep seating plus a nylon insert that helps develop prevailing torque in the thread. A spotted shaft gives the point a defined pocket, so the set screw can locate more positively during installation. 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.

Fixture stops and production tooling can use the pointed seat to hold a repeatable location through repeated handling.

Cold Headers supports distributor, OEM, and MRO sourcing when the item has to be defined by size, point, material, drive, and insert. Review thread size, length, hex key size, point style, and mating-surface marking tolerance before replacing it with another set screw.
