I have found that surplus surveying transit/level leveling screws have worked well for me, plus they come with an adjusting knob/wheel and bottom swivel (maybe not good, ie. possible minute horizontal free play) . Surveying repair businesses usually carry spare parts.

I have not found the need to use extra fine pitch screws for leveling. I use national fine pitch socket head screws and grind the end to a dome shape. By using a long handle allen wrench to turn the screws I can get all the fineness in the adjustment I need.
