Pitch distance for bolts
WebbThe metric system’s “pitch” is commonly viewed as the reverse of TPI in that it is the “DISTANCE” measured between two adjacent threads. Thread Pitch As a fastener manufacturer, we understand that there are many … WebbMetric thread specifications are different because the thread pitch is defined by the distance between each thread in mm instead of threads per inch. For example, an M12x1.75 (coarse) thread has a 1.75mm pitch, while an M12x1.50 (fine) thread has a 1.50mm pitch. Both DIN and ISO standards for metric threads ignore the pitch callout on …

Pitch is the distance from the crest of one thread to the next. Because the vast majority of screw threadforms are single-start threadforms, their lead and pitch are the same. Single-start means that there is only one “ridge” wrapped ...
