Ray:
We use the Simpson 1/4 by X" "Strong Drive" (SDS series). We get them in
the hot dip galvanize version. They are readily available locally. I
think building officials like the Simpson name on structural
products. They self drill and we have had no instance of them snapping off
while being driven.
