About this part

This is the nut from Roger Clark Motorsport's 14/12mm Superstud head stud system for the EJ20 and EJ25, sold as a single piece under part number RCM2866-8337. The 14/12mm figure is the Superstud's stepped thread, not a standard metric size.

We have not run this part ourselves — the ones we have are marked on our cars.
