Exhaust nut size?

[toast]

I lost a nut replacing my midpipe this morning. I have no clue where it went- my garage isnt that big, but anyways, its the bolt that connects the midpipe to the exhaust manifold. The "head" or whatever was 18mm but I need the thread size and pitch and all that, does anyone know what size it is?

take one of the others off and go with it to the hardware store?

I always replace the studs and nuts when I change out the mid-pipe for the first time on a car anyways, my local ace hardware place has a great selection of heat treated automotive studs and matching nuts.

Yea I will resort to that if I have to, but the car is my only means of transportation and Im driving it on 3 as it is. Not to mention 2 of them are pretty tough to get to. I was just hoping someone had the info handy. Maybe Ill be able to call Ford in the morning and see if they know.

If anyone ever happens to search this thread, the nut/bolt is M12 - 1.75.
