For use on a rusty 7/16 bolt head?

What? I use a 7/18" wrench all the time.....

For use on a rusty 7/16 bolt head?

Wouldn't 7/18 be smaller than 7/16?

Wouldn't 7/18 be smaller than 7/16?

Yes. And typically the rusty bolt head is as well.

Yes. And typically the rusty bolt head is as well.

See I was thinking about rusty flakes making heads a little fatter, or when coated wheel lugs swell and my tire iron doesn't fit anymore haha

From my experience, the rust flakes flake off. The hex always ends up smaller.

How about this observation: 7/18 = 10MM !!! This wrench should disappear by itself. Or maybe labeling a 10MM as 7/18 keeps it from disappearing.
