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.

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

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.

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

Easier to machine than 52100 alloy steel rods, these extremely hard and wear-resistant tubes are often used to create bearings, bushings, and other cylindrical parts that are under constant stress. They’re also known as chrome steel.

The addition of molybdenum gives 316 stainless steel excellent corrosion resistance. Use it in a variety of marine and chemical-processing applications.

Precision ground on the top and bottom, these bars have a tight thickness tolerance of ±0.002".

Powdered bronze is pressed and then impregnated with SAE 30 oil to make this material self-lubricating.

These bars are precision ground on the top and bottom for a tight thickness tolerance of ±0.002".

The addition of MDS gives these tubes exceptional wear resistance along with a self-lubricating surface. They're made of cast nylon 6, making them easier to machine and better electrical insulators than other MDS-filled nylon tubes.

At only half the weight of glass, polycarbonate maintains excellent impact resistance across a wide temperature range. It's comparable to Lexan, Hyzod, Tuffak, and Makrolon.
