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.
For technical drawings and 3-D models, click on a part number.

Thumb nuts fasten and position lead screw components. Thumb nuts are easy to grip and tighten by hand for quick assembly and disassembly.

Handles fasten and position lead screw components. Handles are easy to grip and tighten by hand for quick assembly and disassembly.
