The Advantages of ACME Threads

ACME threads have been around for a number of years, but continue to be a critical part of many machining and tool designs. In fact, despite the fact that this thread design is not new, it remains the best choice for many applications. These are a few of the benefits of ACME threads.


There is often a tendency to gravitate toward the latest and greatest device or technology. After all, the thinking goes, the new design must surely be superior to the old design. In the case of ACME threads, however, the design has been well established for decades because it works.

ACME thread design dates back more than 100 years. The ACME standards that are in use today were adopted in 1952. This design has proven the test of time so you can be confident in its performance.


ACME threads are available in a variety of forms and fasteners. ACME fasteners include lead screws, studs, and threaded rods. ACME threads are also available in several forms, including general purpose, centralizing, and stub.

General purpose ACME threads are available in 2G, 3G, and 4G categories. Centralizing ACME threads are currently available in 2C, 3C, and 4C categories. The older 5C and 6C threads are now deprecated. ACME stub threads are classified by the threads per inch and diameter rather than an alphanumeric category.

ACME screws are commonly made from stainless steel, though other alloys may also be used. In addition to the variety of forms and fasteners, a variety of matching fasteners are available for use with AMCE-threaded rods, studs, and lead screws. Material options for matching fasteners include plastic, bronze, and stainless steel.


ACME-threaded fasteners have stood the test of time in large part because of their outstanding reliability. It is not uncommon to find machinery that is decades old and still operating with the original ACME fasteners.
