Not for the freewheel sprockets,
AFAIK. But the freewheel itself is very nice; all the splined sprockets are the same pattern/diameter, so any splined sprocket can be used in any position on the freewheel. The smallest sprocket (or second smallest, if you have one of those new-fangled 6-speed units) is threaded and holds the splined sprockets in place.
of course, my limited knowledge of Zeus suggests that while their designs can be heavily "inspired" by other companies' products, there are often slightly different threads or key dimensions, thus preventing interchangeability.

(although I do have some plastic Zeus dustcaps on Campy pedals)
Most of the components are pretty standard. But while the pedal dustcaps will thread into a Campagnolo pedal, they're slightly different diameter spline pattern so the Campagnolo tool won't work.
