This thread is a globally standardized thread it replaces older metric thread and most threads with inch dimensions The label consists of the letter M followed by a number indicating the nominal diameter the thread angle is 60 176
The Acme thread form has a 29 176 thread angle with a thread height half of the pitch the apex or crest and valley or root are flat This shape is easier to machine faster cutting longer tool life than a square thread The tooth shape also has a wider base which means it is stronger thus the screw can carry a greater load than a similarly sized square thread
