1/4-20 x 3/8 Cone Point Alloy Steel Socket Set Screw with Nylon Insert pairs cone-point shaft engagement with a nylon locking pellet in a compact internal-hex set screw. For best seating, a shallow drilled dimple can help the point center consistently in the intended position. 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.

OEM assemblies with spotted shafts use cone points to separate the locating function from ordinary clamp screws. Half Dog Point Alloy Set Screws with Nylon Insert should be compared when a drilled hole, not a dimple, is the locating feature.

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.
