Mk1 estate manifold stud nut

Post by Ant4567 »

Hi i've fitted a new carb to my citroen bx mk1 estate but discovered that one of the nuts on the manifold stud didnt actually fit the stud. Been searching for one for a while but cant seem to find one that fits the manifold stud. I've heard it is a unf nut but not sure if thats the case. Any help would be greatly appreciated

Is it one of the four carb mounting studs? I'm pretty sure they're M7 on my mk1 16TRS, though whether that's fine or coarse thread I can't remember.

I doubt very much it would be UNF on a Citroen, M7 Metric fine as per Kitch would make more sense.
