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 number of thread starts. Class 7e and 7H components are compatible.
Lead Screws—Right-Hand Thread
 |
Black-Oxide Carbon Steel—Black-oxide carbon steel components have mild corrosion resistance.
Travel Distance per Turn—Travel distance per turn, also known as screw lead, is the distance a nut moves with one revolution of the lead screw.
