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.
Carbon steel lead screws and flanges have good machinability. Black-oxide alloy steel lead screws are hard and strong. They have mild corrosion resistance. 303 and 304 stainless steel lead screws and flanges have good corrosion resistance.
Cast iron nuts have good machinability and high strength. 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.

Ultra-Precision Lead Screws and Nuts
Operating with less backlash (play) than 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. All components are corrosion resistant for use in harsh environments. To ensure compatibility, select components that have the same thread type and thread size.
Travel distance per turn, also known as screw lead, is the distance a nut moves with one revolution of the lead screw.
