Single-start and self-locking lead screws and nuts
Acme Lead Screw and Nut, 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, these 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. There are two immediate results of this difference in profile. It is much easier to machine, so Acme lead screws are much cheaper than square lead screws or ball screws. The second difference is a much larger area of contact between the screw and the nut. 

Acme and Lead Screw

Acme and Lead Screw
Acme lead screws and high performance Acme nuts are combined to provide the optimum performance available in this type of lead screw. The highly burnished surface finish of the acme lead screws and low friction bronze and plastic acme nuts yield a smoother, less abrasive action than conventional cut Acme screws or lead screws.
