Selecting Compatible Lead Screws and Nuts

Metric Precision 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, select components that have the same thread direction, size, pitch, and number of thread starts.
Lead screws are 1018 carbon steel for good machinability.
932 bearing bronze nuts have good machinability and wear resistance. Manganese bronze nuts have good strength and wear resistance.
Travel distance per turn, also known as screw lead, is the distance a nut moves with one revolution of the lead screw.

Metric Clamping Lead Screw Collars
Thread these one-piece collars onto a metric lead screw to separate and position components, or use them as an end stop to limit travel. Made of black-oxide steel, they have mild corrosion resistance. Tighten the clamping screws to secure.
To ensure compatibility, please select a collar that has the same thread type, direction, size, pitch, and number of thread starts as your lead screw.
