These metric lead screws and nuts have broad, square threads that are well suited for quick assembly, high clamping forces, and lifting and lowering heavy objects. They're commonly found in hand-powered clamps, vises, grates, doors, and work tables.

Operating with less backlash (play) than Precision Acme Lead Screws and Nuts, these provide more reliable movement in automated systems. The nuts are plastic, so they do not require lubrication.
