The thread has zero effect on the movement. the entire distance is
strictly and only a function of the diameter of the shaft (threaded
rod) and the diameter of the wire.

one diameter of the wire and the diameter of the shaft.

a 1 inch diameter shaft will have a circumference of pi or 3.14159
inches.

the center of the wire on the shaft would be one half of the wire
diameter for the incomming and outgoing, so it is equal to one wire
diameter.

the pitch of the thread is strictly and only used for seperation of
the wire so it does not rub itself and does not slip or jump over
itself.
