Acetal—Acetal nuts have good wear and corrosion resistance.
Wear-Compensating Spring—Flange nuts with wear-compensating internal O-ring or wear-compensating spring maintain a tight fit even when their threads begin to wear. They resist backlash to maintain accuracy over time, which is important in positioning applications such as 3D printing and robotics.
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.

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.
Externally Threaded Nuts—Right-Hand Thread
 |
Combine externally threaded nuts with a flange to create a custom flange nut.
PET—PET plastic nuts are lightweight and corrosion resistant.
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.
