Steve,

We're talking ballscrews. 5/8 diameter, .200 lead (5TPI) which is probably
the most common ballscrew in existence. When used with a full step stepper
drive these will give a resolution of .001". Half-step and you'll get
.0005".

Infamous?!? Probably because ballscrews, like most things, are made in
differing quality levels, and the person who pursues price only may feel
"burned" when the screws do not meet expectations... Not the screws
fault :-)

Hope this helps.
