At the International Builders Show in Las Vegas I was able to demo the new Quik Drive Cordless 250G2 stand up screw gun. It uses the 2500 rpm DeWalt driver and the kit includes 2 4ah batteries. .

I’ve been in discussions with our engineer because while “glue & screw” is often considered “best practice” it may not necessarily be allowed for the floor diaphragm construction. Your engineer may specify a 10d nail common, to fasten subfloor to joists. What is the equivalent screw for a 10d common? The @Strongtie WSV subfloor screw is the only fastener to be “dual-evaluated under ICC-ES AC233 and AC120 for wood-frame subfloor fastening.” What does that mean for you and me? These screws have the lateral, shear and withdrawal values that exceed those of 10d common nails. No more square drive! The 6 lobe T25 bit strips much less. Every box of screws comes with a bit.
.
.
The other advantage on the labor side is that we can fasten subfloor without bending over. It is a little slower than blasting away with a gun, but by the time the floor is sheathed we’ve found with a good rhythm that total time isn’t increased and a screwed floor is less likely to squeak.
