Having replaced my dud little electrical screwdriver with the cheapo MacAlister one from Screwfix I am now searching for the best bit size for slotted screws which are in light switch and 13A sockets.
Measuring the width they look to be about 7mm.
So do I co for a 7mm bit, or slightly under size with a 6mm bit?
I seem to be awash with Posidrive bits at the moment but not ones for slotted screws.
Cheers
