Z axis screw? On what kind of machine? If mill, is that a knee screw,
quill screw,
or head lifting screw? Is the screw shielded, covered, with bellows, or
out in the
open? Ballscrew, Acme or 60 degree thread? It all makes a difference.

If the screw is mostly shielded from chips and dust, grease would be
good. A
very good lithium or Molybdenum disulfide grease would be good for Acme
or 60 degree threads. Lithium may be best for ballscrews, as some
people have
had the balls slide and develop flat spots when using moly grease, it is
so slippery
the balls won't roll!

Machines with autolube or single-point lube systems usually use way oil
on the
ballscrews, although I'm pretty sure it is not the best lube for them.
