5/16-24 x 1 Cone Point Alloy Steel Socket Set Screw with Nylon Insert is designed for headless fastening locations that need a pointed seat and added thread friction. In a properly prepared seat, the conical point can resist rotation and axial slip through geometry rather than clamp friction alone. 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.
Machine setup blocks and adjustable stops can use a cone point when the final position is intended to stay fixed. The nylon element limits service temperature compared with an all-metal set screw, so review heat exposure before specifying 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.
