Selecting Compatible Lead Screws and Nuts

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.
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.
For technical drawings and 3-D models, click on a part number.

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