5/16-24 x 3/4 Flat Point Alloy Steel Socket Set Screw with Nylon Insert supports repeated adjustment because the flat point spreads contact over a full bearing face. 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.

Pelletized flat point screws keep the thread-locking feature separate from the non-penetrating point geometry. Cold Headers has supplied specialty socket fasteners since 1962 and keeps point style, insert type, and size language clear. Check thread size, length, socket size, pellet dimensions, shaft-flat condition, and surface-marking tolerance before substitution.
