1/4-20 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. 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 can discuss pelletized set screw needs when a print requires prevailing torque in addition to point engagement. 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.
