3/8-24 x 5/8 Cone Point Alloy Steel Socket Set Screw with Nylon Insert is a heat-treated alloy steel cone point socket set screw with a nylon insert for thread drag after seating. 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.
Industrial repair work sometimes calls for cone point nylon-insert screws when removal access is from the socket end only. Nylon and brass tip set screws protect the shaft surface, while a nylon insert locks the screw in its thread.
The locking pellet is installed after the screw body is identified, keeping the insert function separate from the cone point geometry. 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.
