    industrial info icon

    Compare lead screws and nuts by the size, direction, fit, and starts of their threads.

    Metric Lead Screws and Nuts

    Image of ProductInUse. Front orientation. Contains Inset. 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 number of thread starts. Class 7e and 7H components are compatible.
    Lead Screws—Right-Hand Thread

    Extreme-Pressure Iron and Steel Threaded Pipe Fittings

    The strongest steel fittings we offer, these can withstand extreme-pressure applications.
    Note: The maximum pressure listed for Class 6000 fittings is for conditions where there are no sudden changes in pressure or velocity. Please refer to ASME B16.11 to determine the specific maximum operating pressure for your application.
