1/2-13 x 7/8 Cone Point Alloy Steel Socket Set Screw with Nylon Insert identifies the exact thread and length for a locking cone point set screw with internal hex installation. The cone point is selected for mechanical interlock because the tapered tip seats into a spot or dimple instead of only pressing on the surface. 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 controls, handles, and knobs can use cone point set screws when the control shaft is intentionally prepared for the point.
In-house pellet installation helps Cold Headers support nylon-insert requirements that are easy to confuse with plain cone point screws. Cold Headers provides specialty set screw support for maintenance teams that need the same length and locking style already in use. Review thread size, length, hex key size, point style, and mating-surface marking tolerance before replacing it with another set screw.
