I should have been more specific... the screws to which I am
referring are those commonly provided for securing the cards
in their slots. And they shed metal not only from the screw
but from the rear of the chassis they thread into.

In fact, everytime you insert one of these, it has a 50%
chance of rethreading the hole.

Look at them carefully... they have a noticable taper.

That's *one* way to encourage them to stay put.
