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?

    What about dissimilar metals? Galv steel boxes, brass inserts and steel screws?
  • I don`t like slotted, when I was brung up that`s pretty much all there were but times have changed, I prefer pozi, and yes they can look good too.

    Whichever ones you use though use them correctly, I hate it when they are screwed in at an angle from the perp (unless good reasons dictate otherwise)

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

    I wonder if any research has been done on system noise generated from galvanic effects?

  • Which allows you to nip them to length using the hole in your side cutters, as I tried to explain to a bloke who said he needed new screws in his fittings, because they were too long.

    Noise generated by the face plate fixing screws?

  • Hello Alex.

    With all due respects, my view is the exact opposite to yours!  Slotted screws are all easy to deal with.  Get to the awkward inner recesses of a cupboard, roof space or an elevated light fitting only to find find oddball screw heads......b****cks!  Are they Phillips, Pozidriv or Torx?  It sometimes even needs a torch to identify what's lurking in there. The correct driver is vitally important.  Now we need a full suite of four different driver sets for no good reason.  Rant over!

  • Then you find the cover of the electric heater is fixed on with security screws with a dimple in the middle, so you need a security screwdriver set!


    edited because spellchequer changed cover to government. This forum has become dreadful to post on, what’s with the auto saved dialogue box? You can’t see what you are writing in the slit that is the box to write in.

    These other screw heads were designed for easy alignment, and keeping engaged in the screw head whilst turning the driver & juggling wires & fitting. A badly fitting slotted driver will chew up the head as fast as the wrong Pozi driver.

    A major improvement would be one wire per hole, instead of trying to catch 5 earth tails in one piddling little terminal.
