The count of the threads is 8 in a 1 inch length. However when the nut is

This is called an Eighth-in. pitch/two-start. Instead of ONE thread around
the screw, there are TWO. Some screws are made with three and even
FOUR-start! I built a couple of plotters with 1/8" pitch/four-start. Make 1/2" move
per turn!
