5-40 x 5/16 Cone Point Alloy Steel Socket Set Screw with Nylon Insert supports permanent or semi-permanent shaft settings where the point is intended to seat into the mating component. 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.

Maintenance repairs often need the exact thread, length, point style, and locking insert that match the service record.

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. The internal hex recess also keeps installation access compact when the screw is recessed in a hub or collar.
