1/4-20 x 1/2 Flat Point Alloy Steel Socket Set Screw with Nylon Insert supports repeated adjustment because the flat point spreads contact over a full bearing face. The flat point clamps by friction, so it is commonly chosen for shafts that should not be intentionally marked by a biting point. Use the heat-treated alloy steel body with the nylon locking pellet where the application calls for mechanical fastening rather than stainless material.
OEM assemblies pairing flats on shafts with flat points use the mating geometry to spread contact across the seat. 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.
Cold Headers can help identify the correct flat point alloy set screw when the drawing calls out a locking insert. Check size, socket, pellet dimensions, and surface-marking tolerance before substitution.
