7/16-20 x 3/4 Flat Point Alloy Steel Socket Set Screw with Nylon Insert combines a flat bearing point, internal hex drive, and nylon locking pellet for adjustable machine settings. 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.
The 7/16-20 fine-thread rows are uncommon in this flat point locking family, so exact thread identification is important. Cold Headers supports industrial distributors, OEM buyers, and maintenance teams when a set screw must match the existing print. Check size, socket, pellet dimensions, and surface-marking tolerance before substitution.
