second, detecting these, it is detected during the production process. Starting from the head of the screw, determine the head size, head-to-edge, diagonal, cross groove depth, screw tolerance range, and so on. These are all detected with a caliper.

Then it is the detection of all aspects of tooth decay, the main thing is whether the thread can pass the through stop gauge, the screw thread can pass the regulation, and the regulation is stopped.
