In the metric system, the threads are expressed in millimeters per thread. An M5-0.4 x 15 has a thread for every 0.4 mm. Step 3: Reading the third number The third number is typically the one after the x, and it prescribes the length of the screw. You measure them all from the bottom of the head down to the tip.

With metric threads tapping drill size is easy to work out because it is the bolt diameter minus the thread pitch so, for example, a standard pitch M16 bolt has a pitch of 2.0mm so the tapping drill size is 16 - 2 = 14mm. The table below gives tapping drill sizes for threads corresponding to the thread pitches given in the table on page 3.
