1/4-28 x 7/8 Cone Point Alloy Steel Socket Set Screw with Nylon Insert pairs cone-point shaft engagement with a nylon locking pellet in a compact internal-hex set screw. 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.
Pulley hubs and sheaves often use cone points when a prepared seat is available and the setting should not creep in service.
Cold Headers has worked with specialty socket fasteners since 1962 and supports exact thread-and-length identification for repair and production work. Review thread size, length, hex key size, point style, and mating-surface marking tolerance before replacing it with another set screw.
