10-24 x 1/4 Flat Point Alloy Steel Socket Set Screw with Nylon Insert is a compact locking set screw for parts that need internal hex access and a non-penetrating point. Use this style where the assembly needs a broad bearing face and a separate thread-locking feature. 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. Do not treat plain alloy steel as corrosion resistant; protect or oil the part when the environment demands it.
The catalog keeps this family separate from plain flat point screws so the nylon insert requirement remains visible. Check size, socket, pellet dimensions, and surface-marking tolerance before substitution.
