Don't know about size but they're also called triple squares. The spline is a square rotated three times.

If it is the M12 bit you are referring to that relates to the thread on the bolt. It gives you an idea of how coarse the thread is. It has nothing to do with the size of the tool needed.
You can pick up spline tool sets pretty cheap. It's not a bad investment as audi use spline bolts a fair bit on their cars.
