5-40 x 3/8 Cone Point Alloy Steel Socket Set Screw with Nylon Insert is the alloy steel nylon-insert version of a cone point socket set screw for compact machine assemblies. This double-action layout combines point seating at the shaft with prevailing torque inside the threaded hole. 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.
Conveyor drive components may use this family in collars, hubs, and adjustments where compact thread locking is useful. A stainless cone point screw with nylon insert is a non-catalog request Cold Headers can quote when the environment calls for it.
Since 1962, the Cold Headers catalog has focused on socket products that are easy to misidentify without careful size language. Review thread size, length, hex key size, point style, and mating-surface marking tolerance before replacing it with another set screw.
