That Zeus arm (I have several like it) has the 22.0mm Campy extractor thread. But I don't know if that is to the the base or the crest of the thread. The thread depth is probably about 1mm, so which way the thread diameter is measured would determine whether a 21.8mm OD socket would fit or not. You probably have to try it and see.

If the ID of the recess in a Zeus crank is indeed 22mm, as suggested by John Thompson, then the Craftsman 44311, with an OD of 21.8mm should work. Perhaps I should bring mine along next time I'm in the AA area (I get there often) and we could give it a try. :-)
Or you could put the bike in your car and haul it over to the Sears at Briarwood and try one out. ;-)
