Domestic wiring fittings, screw heads

Alex Barrett
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?

    What about dissimilar metals? Galv steel boxes, brass inserts and steel screws?


    I guess that's one reason most decent electrical screws are brass - nickel plated for faceplate ones.
