1/2-20 x 1 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. 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.

Cold Headers supports industrial distributors, OEM buyers, and maintenance teams when a set screw must match the existing print. Check thread size, length, socket size, pellet dimensions, shaft-flat condition, and surface-marking tolerance before substitution.
