5/16-24 x 7/8 Flat Point Alloy Steel Socket Set Screw with Nylon Insert identifies the exact thread and length for an alloy steel flat point set screw with a nylon insert. The nylon insert works in the female thread, adding prevailing torque while the point handles surface contact. 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. Do not treat plain alloy steel as corrosion resistant; protect or oil the part when the environment demands it.
Cold Headers focuses on exact-size socket fastener sourcing for production, repair, and plant maintenance needs. Check thread size, length, socket size, pellet dimensions, shaft-flat condition, and surface-marking tolerance before substitution.
