5-40 x 7/8 Flat Point Alloy Steel Socket Set Screw with Nylon Insert combines a flat bearing point, internal hex drive, and nylon locking pellet for adjustable machine settings. The flat point clamps by friction, so it is commonly chosen for shafts that should not be intentionally marked by a biting point. Use the heat-treated alloy steel body with the nylon locking pellet where the application calls for mechanical fastening rather than stainless material.
Handle and control retention often benefits from a headless screw that can be serviced from the socket end.
In-house pellet installation supports uncommon flat point nylon-insert requirements when a standard plain screw is not enough. 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.
