Domestic wiring fittings, screw heads

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?

  • If a tunnel is sized to a screw and the screwdriver is sized to the screw, a Standard insulated screwdriver with insulation bigger than the head of the driver cannot possibly fit in the tunnel to access the screw.


    So unless you have a slim or uninsulated screwdriver you will end up using a screwdriver a size smaller than it should be and struggle to do a good job.


    So your tool bag needs decent set slim insulated screwdrivers, plus a micro screwdriver set, Security bit set and a torque screwdriver set, however you may still need to buy a few more bits and drivers to complete your sets in addition to those like pozi number three and big slots.
