Compare lead screws and nuts by the size, direction, fit, and starts of their threads.
Acme Lead Screws and Nuts
 |
Found in hand-powered clamps, vises, grates, doors, and work tables, lead screws and nuts have broad, square threads that are well suited for quick assembly, high clamping forces, and lifting and lowering heavy objects. To ensure compatibility, please select components that have the same thread direction, thread size, and number of thread starts.
Lead Screws—Right-Hand Thread
 |
Alloy Steel—Alloy steel components are harder and stronger than carbon steel components.
Travel Distance per Turn—Travel distance per turn, also known as screw lead, is the distance a nut or handle moves with one revolution of the lead screw.
