There is such thing as 'left-handed screws', but you do not see them
very often. Most of the time, there is a 'right-handed screw' at the
other end, thus a turn of the screw either separate or bring closer the
parts with the bolts (symmetrically!).
Typical application: pairs of compass for technical drawing.
