Default my04 STi exhaust to turbo bolt size?

hi guys, does anyone know the size of bolt joining the up-pipe (or is it called the downpipe?!) to the turbo? One of mine is missing a nut that I want to replace, but can't figure out the diameter nut and pitch that I need. I know it's around 10mm/7/16" coarse thread, but can't quite figure it out. I'm pretty sure it is the same as this nut:
Subaru OEM Downpipe to Turbo Exhaust Nut Subaru Turbo Models 902370029 at RallySportDirect.com

I can't find dimensions on the page, and need to get a nut on there ASAP

M10x1.25 pitch.
You can't use a generic nut as it needs to have a 14mm hex or you will struggle to get a spanner on it.

ie you have the wrong nut, you need a ISO fine 1.25P nut not ISO coarse 1.5P.

Probably is now after trying to put a 1.5 pitch nut on a 1.25 bolt.

Sorry I meant to say 1.25 the first time, typo. Could it be heat damaged, which isn't letting the nut thread on?

Take one of the other nuts off and see if it fits.
