i recently discoverd the best tool ever for putting in fasteners!
it's an impact driver. Looks like a regular cordless drill, but it uses the magic of an impact driver to do all the work. This tends to strip fewer heads, and also does not twist the arm of the person using the tool, unlike a standard drill, and it has about 10 times the torque of a standard drill.
when i say magic, i'm not kidding! How did i ever live without one of these! It's my new favorite tool.
