Hi Jason:
"Lead" refers to the distance a nut will travel in one revolution of the
screw.
On a single start screw(only one groove for the balls to track in) the lead
is the same as the pitch.
On a multistart screw the lead will be a multiple of the pitch, and the
multiplier will be the number of starts.
So a screw with three grooves around its periphery will have a lead that is
three times the pitch.
Multistart screws are useful if high forces must be absorbed on components
that are accelerating or decelerating quickly.
Hope this answers your questions
Cheers
Marcus
