7/16-20 x 5/8 Flat Point Alloy Steel Socket Set Screw with Nylon Insert is built for no-mark clamping where a broad flat face bears against the shaft instead of biting into it. A prepared flat on the shaft gives the point a full-width seat and improves holding contact without penetration. Use the heat-treated alloy steel body with the nylon locking pellet where the application calls for mechanical fastening rather than stainless material.
Drive collars and light hub assemblies may specify this style when shaft protection matters more than a point bite.
Cold Headers can review non-catalog flat point set screw needs when the application requires a nylon insert. The 7/16-20 fine-thread rows are uncommon in this flat point locking family, so exact thread identification is important. Since 1962, Cold Headers has helped buyers sort closely related socket products that can be easy to confuse. Check thread size, length, socket size, pellet dimensions, shaft-flat condition, and surface-marking tolerance before substitution.
