            Miniature Lead Screws

            Miniature Lead Screws

            With diameters as small as two millimeters and optional anti-backlash nuts, Thomson miniature lead screws enable designers to achieve small-scale designs once considered impossible. Configurable, customizable and lean, these lead screws help reduce the size and weight of applications without compromising precision, life or function.
