I've got a box of number 9 2 1/2 inchers that ought to do the trick.
Question: Is there a formula for determining the minimum gauge for a
screw if you know the load?
When in doubt, put in another screw for redundancy. If
they're going to fail, in all likelihood, they're going to fail
one screw at a time.
