A bit of a joke, but what about the power driven staples for wood joists? I doubt the staples are listed either. The detail for a metal deck with concrete fill, which is what I have, says nothing on the size. I would assume it's the same but some more guidance would be helpful. In Montana, we have no jurisdictions that give guidance, it's all per 13.
