I agree with tnom. I call them a hand impact driver. Position
the tip, crank to the left, hit with a hammer. It will take out
some mighty stubborn screws, like stripped out #3 Phillips head in
hinges, etc.

Hi,

Any creative tips for removing screws whose heads have nothing
to
catch? These are neither regular or Phillips Head screws. They
have
a special bit, kind of in the shape of a square. Anyway, the
inside
of the head is now a round, smooth circle.

Any ideas for removing them would be appreciated.

Thanks in advance.

Take a spare Robertson bit and shorten it by a small amount
leaving sharp corners. The bit is tapered so that it should also
be a slight bit larger and impossible to bottom out completely.

Next take your special made bit and attach it to a impact driver
