1/2-20 x 3/4 Flat Point Alloy Steel Socket Set Screw with Nylon Insert is chosen when a flat point should seat on a shaft flat while the nylon insert resists backing out. This point style is useful when the part may be loosened, slid, and reclamped during changeover or setup. Use the heat-treated alloy steel body with the nylon locking pellet where the application calls for mechanical fastening rather than stainless material.
Finished shafting, control rods, and small mechanical linkages can use a broad contact point to reduce marring. ASME B18.3 places flat point diameter in a qualitative band of about 0.55-0.62 times nominal screw diameter, so confirm the mating seat rather than substituting a sharp point.
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.
