The Easiest Way to Read a Screw Thread Callout

Jun 12, 2019· For metric threads, the thread pitch is given in millimeters per thread Thus, an M2 x 04 screw has threads every 04mm Although most metric fasteners have two or more standard pitches (fine & coarse threads), the pitch is often omitted from a thread callout; it is always helpful to carry a sample with you to the hardware store.
