I have changed and added light switches, receptacles, etc. over the decades and a standard Phillip's # 2 or Flathead screw driver will only get you by.
This tool is specially designed for the above terminals and a please to use, staying in place while loosing or tightening the screws.
I highly recommend this screwdriver. Milwaukee has been one of my favorite tools which is First Quality all the way...."most of the time, you get what you pay for."
