We are manufacturing the flat point set screws in the cutting work. Therefore, the flatness accuracy of the flat point set screws is less than 0.01mm. In addition, the squareness of the threaded portion and the flat portion is less than 0.01mm. And, the variations of the flat diameter is less than 0.02mm.

Free-cutting steel (ASK2600S) is easy to be rusted, our standard stocks offers black or white zinc plating (trivalent). Other plating (electric nickel plating, electroless nickel plating, etc.) is possible as a special order product.
