CO2 front exhaust plug size

I recently had my bike at a dealer who checked the CO2 level, he had to drill out the old exhaust plug and replace it with a new one. After driving hundreds of miles around Scotland and returning home, I was changing my round cans back to the oval ones I normally run when the panniers are removed; and noticed a hole in the pipe where the plug should have been. I guess he didn't put thread lock on it, but have had to put a large bolt in the hole not threaded with a jubilee clamp to hold it in to stop the gases escaping.
My question is what thread and pitch size is this bolt as I can't find it in the torque setting of the service manual? this is an ST2 BTW.
I have one on an old set of down pipes I have but no amount of penetrating lub and an impact driver will shift it. The rear plug from the vertical cylinder is a different size as this one I could remove but it is smaller in diameter.
I'd like to fit one with a hexagonal head as I'd have more chance of removing it in future if it got stuck again.

I just lost one myself. Try probolt. They offer a uk site. I'm almost sure it's an M10x1.0 plug. I checked the thread pitch from the second header plug. Shame on motowheels for selling these for 10 bucks.
Here is one from a usa source. https://www.belmetric.com/dp10x100ah-metric-drain-plug-p-508.html?cPath=11_90_869
