Selecting Compatible Lead Screws and Nuts
More
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 and size.
360 brass nuts have excellent machinability and good corrosion resistance. 932 bearing bronze and 673 bronze nuts are wear resistant. They have good machinability and fair corrosion resistance. PET plastic nuts are lightweight and corrosion resistant.
Travel distance per turn, also known as screw lead, is the distance a nut moves with one revolution of the lead screw.

Combine externally threaded nuts with a flange to create a custom flange nut.

Fast-Travel Precision Acme Lead Screws and Nuts
Multiple thread channels (also known as thread starts) create faster linear travel than lead screws with a single thread start. The threads have a tight thread fit for accurate, repeatable starts and stops. Pair with a motor in automated motion and positioning applications. To ensure compatibility, please select components that have the same thread direction, thread size, and number of thread starts.
