I'm in the Milwaukee camp. Among other projects in the past year I've rebuilt 3 piers at 400' each, using 3" stainless steel screws. The screw count on these 3 projects alone is around 15,0000. I don't have a count on the 5/8" X 12" piling bolts replaced, but it was a bunch. There was also 1000's of 1 1/4" and 1 5/8" strap screws replaced on conduit and water lines. Plenty of saltwater contact along the way, plus rain and sand. All work completed with one slightly used M18 and 2 batteries.
