I know that to use an electric screwdriver it's better to use a screw with a Philips or Torx drive, but sometimes you need to use or find yourself in situations where you need to work with a slotted drive screw and they are very annoying to work with because the electrical screwdriver keeps slipping from the screw slot.
So my question is: How to prevent an electric screwdriver from slipping when tightening/loosening a screw with a slotted drive?
