My impression is that when framing a wall using 2 x 4 construction most people use framing nails and either a hammer or a nail gun. Do people use screws? I was building some walls for a shed and I don't have a nailer. After botching a few (I think I was trying to drive through a not or something) I started to wonder if it might be easier on my arm and faster to use 3" screws and an impact driver. I imagine that the screws are more expensive, but for a small shed it wouldn't be a factor. Is that a reasonable option and is it something that's done out there in the construction world? If I decided to try that, do I need to pre-drill standard 2 x 4's or are they soft enough to just drive a #10 3" decking screw through?
