Is there a reason why all conventional domestic electrical wiring fittings use exclusively slotted screw heads, rather than the much more practical Phillips or Pozidrive heads? Don't tell me that electricians can only carry one screwdriver?
You do actually need a Slim VDE screwdriver or an uninsulated screwdriver to work with screws in tunnels, if you use a standard insulated screwdriver the head of the screwdriver cannot possibly fit correctly, because it is smaller than the insulation.
