1/4-28 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. This point style is useful when the part may be loosened, slid, and reclamped during changeover or setup. Use the heat-treated alloy steel body with the nylon locking pellet where the application calls for mechanical fastening rather than stainless material.
Instrument and control components may need the no-mark behavior of a flat point along with an internal hex drive. Because the insert is polymer, review heat exposure when the application would otherwise use an all-metal screw.
Cold Headers has supplied specialty socket fasteners since 1962 and keeps point style, insert type, and size language clear. Check thread size, length, socket size, pellet dimensions, shaft-flat condition, and surface-marking tolerance before substitution.
