Selecting Compatible Lead Screws and Nuts

Metric Precision Lead Screws and Nuts

Also known as trapezoidal-thread lead screws and nuts.

Metric Fast-Travel Ultra-Precision
Lead Screws and Nuts

Multiple thread channels (also known as thread starts) create faster linear travel than lead screws with a single thread start.

Metric Ultra-Precision Lead Screws and Nuts

Also known as single-start and self-locking lead screws and nuts, these 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.

Metric Lead Screws and Nuts

These metric lead screws and nuts have broad, square threads that are well suited for quick assembly, high clamping forces, and lifting and lowering heavy objects. They're commonly found in hand-powered clamps, vises, grates, doors, and work tables.

Ball Screws and Nuts

Also known as single-start ball screws and nuts, these have a single thread that runs the length of the screw. They operate with more torque than fast-travel ball screws and nuts.

Fast-Travel Ball Screws and Nuts

Multiple thread channels (also known as thread starts) create faster linear travel than ball screws with a single thread start.

Metric End Supports for Lead
Screws and Ball Screws

A set of ball bearings reduces friction and secures the end of a metric ball or lead screw.

Metric Clamping Lead Screw Collars

Install these threaded collars on a metric lead screw to separate and position components, or use them as an end stop to limit travel.

Roller Screws and Nuts

Precision ground to create more points of contact, these roller screws and nuts are highly accurate and handle much higher loads than ball screws and nuts of the same size.

Ball Screw/Splines and Bearings

From one compact system, transmit linear or rotary motion or both at once (sometimes called spiral motion). Because of these different motions, these ball screw/splines and bearings create efficient, fluid movements in complex automated applications, such as pick-and-place robots.
