Selecting Compatible Lead Screws and Nuts

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 and size.
Cast iron components have good machinability and high strength.
Travel distance per turn, also known as screw lead, is the distance a nut or handle moves with one revolution of the lead screw.

Round nuts move objects along the length of a lead screw.
