7/16-20 x 7/16 Flat Point Alloy Steel Socket Set Screw with Nylon Insert gives purchasing teams a specific alloy steel flat point nylon-insert size for replacement work. 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.
Packaging equipment and indexing hardware may use the nylon insert where vibration can work against thread friction. 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. For replacement work, Cold Headers helps keep thread, length, material story, point style, and insert function aligned. Check size, socket, pellet dimensions, and surface-marking tolerance before substitution.
