For many thing that come with screws, the quality of screw often

+1, I have a box full of such things which I would not dream of using
but am too mean to throw out. (To be fair, the plugs go in there as
well, and I sometimes find one which is worth salvaging to use).

Also, PH is the spawn of the devil, IMHO. Surprised no-one else said
so. Nice to find it is becoming less common even on machine assembled
stuff, e.g. the way washing machine backs are usually Torx these days.


They are handy for some things... dry lining screws for example, where
you want the behaviour they were designed to exhibit (i.e. to cam out
once a certain level of torque was reached)

Fair point (although you don't even need that if you use the special
bits with a collar).
