It is critical that new screws and copper seal rings be fitted any time that injectors are removed and replaced. These are the original Mercedes Benz screws and are not a hardened bolt. They are a "stretch bolt" or as more formally known, torque to yield. Do not use any other bolt on your injectors and never re-use an old bolt/screw.
