7/16-20 x 1 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.
Large 5/8 flat point nylon-insert sizes support heavier collars and hubs where the print still calls for shaft-friendly contact.
The 7/16-20 fine-thread rows are uncommon in this flat point locking family, so exact thread identification is important. The catalog keeps this family separate from plain flat point screws so the nylon insert requirement remains visible. Check thread size, length, socket size, pellet dimensions, shaft-flat condition, and surface-marking tolerance before substitution.
