    Precision Acme Lead Screws and Nuts

    Image of ProductInUse. Front orientation. Contains Inset. Precision Lead Screws and Nuts. Precision Acme Lead Screws and Nuts.
    Pair with a motor in automated motion and positioning applications. A tight thread fit allows these lead screws and nuts to make accurate, repeatable starts and stops. Also known as single-start and self-locking lead screws and nuts, they have a single thread that runs the length of the screw. The nut travels only when the screw turns, so your system won’t unexpectedly move when the lead screw is at rest. To ensure compatibility, please select components that have the same thread direction, thread size, and number of thread starts.
