Default catalytic converter bolt size

I did a search and only found that they are studs and pressed in or whatever.

I need to know the size of the bolt/nut.

My mom's 99 accord had two nuts come off from the bolts connecting the b-pipe to the catalytic converter and it's hella loud.

Just trying to head to wal mart and pick up the right nut so I can make her car quiet again.

They are more punches than anything....not really mechanic looked at it again and said I was correct and welded it shut.

No big deal. $20.
