8-32 x 5/16 Flat Point Alloy Steel Socket Set Screw with Nylon Insert fits applications that need a headless internal-hex screw, broad point contact, and a locking insert. 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.
Fixtures that move between production runs may use the flat face to reduce surface damage during repeated clamping. Do not treat plain alloy steel as corrosion resistant; protect or oil the part when the environment demands it.
Pelletized flat point screws keep the thread-locking feature separate from the non-penetrating point geometry. 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.
