Selecting Compatible Lead Screws and Nuts

Metric 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, size, and pitch. Class 7E and 7H components are compatible.
Travel distance per turn, also known as screw lead, is the distance a nut moves with one revolution of the lead screw.
