5/16-18 x 5/8 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. 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.
Common uses include gear and sprocket settings on spotted shafts where rotation control matters after the hub is positioned.
In-house pellet installation helps Cold Headers support nylon-insert requirements that are easy to confuse with plain cone point screws. For uncommon set screw lengths, Cold Headers can quote the requested configuration without substituting a different point geometry. Review thread size, length, hex key size, point style, and mating-surface marking tolerance before replacing it with another set screw.
