The acme thread, with a 29 degree included angle, is also used in presses, jacks, valves or other mechanisms that move heavy loads. Because of the severity and nature of the cut needed to produce acme threads, North American Tool employs specialized engineering and design to manufacture its Acme Thread Taps.

A Trapezoidal Tap is the metric equivalent of Acme Taps but has a 30-degree included angle.
