WebFor internal threads, there are four tolerance classes, 3G5, 3G6, 4H5 and 4H6. (b) Example of external thread S Profile : S0.9 x 0.225 - 5h3 S : Miniature thread symbol 0.9 : Size 0.225 : Pitch 5h3 : Tolerance class 5h : Pitch diameter tolerance symbol. "5" : tolerance grade and "h" : tolerance position 3 : Major diameter tolerance grade WebFor 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 coarse threads. For example, a thread diameter defined as "M12" indicates a coarse pitch (M12-1.75).
