No, Mike, but threading dials are really easy to make. Mine (for an inch leadscrew) has a PVC(!) pinion, fashioned with little regard for the niceties of pressure and helix angles, and I've been using it on and off for 5 years. A metric leadscrew usually needs more than one pinion (often 14T, 15T and 16T or a multiple of each, if I remember right) in which case it's probably easier to make separate dials than to put the pinions on a common shaft and find a way to engage the one you require for a gioven thread pitch.

PS I suppose I should have called them worm wheels rather than pinions.
