Easy question: Size of bolt to plug o2 bung in Catalytic Converter/Test Pipe
Now I am a thread-starting *****. 
I need to pick up a bolt to plug an o2 bung on a Carsound Cat from SMSP (thanks dave!!). I can't get at the bolt that is plugging the o2 bung in my test pipe right now since it is on the car, and need to pick one up this afternoon for another header/cat install tommorrow morning. I know the bolt requires a 22mm wrench, but I don't know the width of the bolt, at least the part where the threads are.
Someone has got to know.... Thanks in advance for helping me out.

Its the same size as a standard drain plug. Just go to the auto parts store with the cat, and find a drainplug that threads in.
