We use 8d nails unless there is a case where 10d nails will work and
there is not a Simpson Strong Wall or equivalent product that will work.
Also, we allow the substitution of 14 ga staples for 8d nails where
possible. There are cases that 8d @ 4" oc will work, but not 14ga
staples at the same spacing.
