5/16-18 x 3/4 Flat Point Alloy Steel Socket Set Screw with Nylon Insert is suited to adjustable collars, stops, and hubs where the setting may be loosened and reset. 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.
Typical uses include adjustable collars and stops on finished shafts where the contact mark must be controlled. A stainless flat point screw with nylon insert is a non-catalog request Cold Headers can quote for environments that require it.
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.
