Treated Lumber is scarce everywhere. The little short torx bits that come with the boxes of screws usually get tossed into a bucket at my house, I buy the recessed bits for impact drivers, I get insanely mad for some reason when one of the little short bits comes out of the holder then drops into someplace I cannot get to without climbing down or under something. It's just one of those things that sets me off, sort of lie getting the screws mixed in my pouch as I will always find that one that is too short or turns out to be a combo head or some such thing. When you are helping someone else and using their screws sometimes you switch from phillips to square to torx and back based on what they have. I pity the poor sucker that ever has to take some of it apart, sure hope it ain't me again.
