5/16-24 x 1/2 Flat Point Alloy Steel Socket Set Screw with Nylon Insert gives designers a surface-respecting set screw option when the shaft should remain usable after repositioning. Because the point does not dig in by design, final holding action depends on the surface condition, load, and seating area. 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.
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.
