What size and pitch are the shock tower nuts front and back on s13 240/180sx

Trying to machine out some custom nuts but forgot to bring samples of them with me today. Anyone know the size? If I can get a clue I can start on them. Any info will help a lot. To be clear I'm working on the three top tower nuts front and two top in rear tower. Yes, I googled but got too many answers.

12mm seems to be the size, I just cant figure out the pitch. I'll work on everything else till I know the answer.
