    Operating with less backlash (play) than Metric Precision Acme Lead Screws and Nuts, these provide increased nut life and more reliable movement in automated systems. 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, select components that have the same thread size, thread type, thread size, thread pitch, and number of thread starts.

    4140 Alloy Steel—Alloy steel lead screws are hard and strong.
    303 Stainless Steel—303 stainless steel lead screws have good 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.

    Multiple thread channels (also known as thread starts) create faster linear travel than lead screws with a single thread start. Operating with less backlash (play) than Metric Precision Acme Lead Screws and Nuts, these lead screws and nuts provide increased nut life and more reliable movement in automated systems. To ensure compatibility, select components that have the same thread size and number of thread starts.
