In order to measure the diameter of a screw correctly, one must note that one measures on the thread and does not accidentally place the caliper between the thread of the screw. If you insert the screw crosswise into the calliper, the probability of a measuring error is very high, because the jaws of the calliper can slip between the threads. The screw must therefore be inserted lengthwise to the legs of the caliper. The diameter of a screw is always measured on the thread.
