5/8-18 x 1 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. Flat point geometry favors surface protection and repeatable adjustment rather than maximum bite into the mating part. 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. Plain Flat Point Alloy Socket Set Screws may fit the job when the nylon insert is not required.

Large 5/8 flat point locking set screws are not always easy to source through general-line channels. Cold Headers focuses on exact-size socket fastener sourcing for production, repair, and plant maintenance needs. Check thread size, length, socket size, pellet dimensions, shaft-flat condition, and surface-marking tolerance before substitution.
