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, and number of thread starts.

Metric Fast-Travel Ultra-Precision Lead Screws and Nuts


	Style A	Style F

Multiple thread channels (also known as thread starts) create faster linear travel than lead screws with a single thread start. Operating with less backlash (play) than Metric Precision Acme Lead Screws and Nuts, these lead screws and nuts provide increased nut life and more reliable movement in automated systems. To ensure compatibility, select components that have the same thread size and number of thread starts.

Ball Screws and Nuts

Internal ball bearings provide smooth low-friction travel in applications that require high speeds, accurate positioning, and repeatable movement. Also known as single-start ball screws and nuts, they have a single thread that runs the length of the screw. They operate with more torque than fast-travel ball screws and nuts. To ensure compatibility, select components that have the same thread direction and size. Ball nuts are furnished with a tube to keep ball bearings in place. Do not remove the tube until you are ready to install the nuts onto the screws.

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.
