Außendurchmesser (m)

outside diameter (n)

Threads are defined by their outside diameter, core diameter, pitch diameter, profile angle and pitch.

The measuring instrument needs to cover at least two turns of the thread to measure the outside diameter of external threads or the core diameter of internal threads.

It is essential for the measuring instrument's contact areas to lie on the thread root when measuring the core diameter of external threads or the outside diameter of internal threads.
