Self-Reversing Lead Screws and Nuts
A crisscross thread pattern allows you to drive the nut back and forth without changing the lead screw's direction of rotation. When the nut reaches one end of the lead screw, it changes direction and travels back to the other end. Also known as diamond lead screws, they're sometimes used to guide cable and wire as it's spooled on a reel.
Travel distance per turn, also known as screw lead, is the distance the nut moves with one revolution of the lead screw.
