Nails are pretty forgiving to the type/size of hammer used. Screws can be pretty finicky, for example using a too-small Philips screwdriver can strip the screw-head, and make it very difficult to tighten further or to remove. I'm pretty fond of those screws that can take a Flathead or Philips screwdriver, though. How about nuts+bolts?
