5/16-18 x 7/8 Flat Point Alloy Steel Socket Set Screw with Nylon Insert provides flat-face contact for controlled friction hold in machinery where shaft scarring is a concern. Use this style where the assembly needs a broad bearing face and a separate thread-locking feature. 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. Cold Headers can quote the requested flat point nylon-insert configuration without changing the point style to a biting design. Check thread size, length, socket size, pellet dimensions, shaft-flat condition, and surface-marking tolerance before substitution.
