Easy way to measure the diameter of the thread

The caliper measurement after threading is usually measured by a threaded micrometer or a three-needle, which is often limited by conditions. If it is measured with a thread micrometer, it needs to be measured according to the different pitch of the corresponding measuring claw. With the three-wire measurement of the thread and the single-wire measurement method, the measurement is more complicated, and generally has to be converted by the calculation formula, so it is far from being able to adapt to the processing needs of large quantities and multiple varieties. A simple general measurement method for measuring the diameter of a thread using a projector and a tool microscope is now presented.
