The Differences Between Lead Screws and ACME Screws

All screws are not created equal, and this is at least partly by design. Fastener screws are manufactured with threads that help to secure the screw in place. Lead screws, on the other hand, are manufactured to allow for consistent motion. These are the differences between lead screws and ACME screws.

Lead screws are commonly utilized in machinery to produce linear motion. The lead screw is fitted to a nut, and the linear motion may be generated by turning either the nut or the lead screw. There are several types of lead screws available.

ACME screws are one type of lead screw. ACME screws are designed with strong threads that are most commonly used for lifting. These screws are easier to manufacture than some other designs, but still offer considerable strength. Common uses of ACME screws include jack screws and vises along with many other applications.

ACME screws are a more economical solution than other options like ball screws. They are also ideally suited to applications that require a heavy load be applied to the screw and that involve slow rotation speeds.

The design of ACME screws typically results in low efficiency. While this may seem to be a drawback, it is often utilized as an advantage. The low efficiency of ACME screws helps to prevent back-driving of the machine apparatus during operation.

ACME screws are available in a variety of diameters and thread pitches. This allows the screws to be used in many different applications. Dependable ACME offers screw threads from 3/8 inch to 2 ½ inches in diameter.
