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?

    Slotted screws stood to an attention are neat and tidy.


    Please tell me that you don't align all the slots in your screws! ?


    If you have a screw and nut, by all means align all the screw heads and tighten the nuts against the screws; but if you do that with wood screws, some will be too tight, and some too loose.
