This is a must have tool when restoring old cars! .....Many times you come accross rusted screws which do not want to move, even with penetrating oil......Heating and drilling only make a mess.........This is where an impact driver comes in handy......Simply place in the bit you need into the tool place in the screw slot and strike with a hammer ........ The impact and twisting motion in most cases will free up the screw....
