5/16-24 x 3/8 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. Because a cone point marks the mating surface by design, it is best reserved for parts where indentation is acceptable. 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.
When a bill of material calls out cone point alloy hardware with a nylon insert, Cold Headers keeps the catalog path specific. Review thread size, length, hex key size, point style, and mating-surface marking tolerance before replacing it with another set screw.
