The types of lead screws based on their thread geometry are square threads, acme threads, trapezoidal threads, and buttress threads. Lead screws can be manufactured by a thread rolling or perhaps a thread whirling method.

Having said that, They can be much less efficient, involve much larger torque to generate, and produce extra friction; this enhances the don of the threads and degrades precision.

Trapezoidal metric threads are just like ACME threads but are measured in millimeters and possess a thirty degree thread angle.

Centralizing acme threads characteristic tighter tolerances involving the exterior and internal threads to cut back wedging underneath radial masses. The Stub acme thread features a shallower thread depth, fewer than 50 % of its pitch, and brings together traits of both of those the overall Reason and Centralizing acme threads.
