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.

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. 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.
