Whats the meaning of M16 . As my experience all of thread have a special pitch . Why the tap hole Dia. of a M16 is 16-(2*1)=14
Tanks for any guide .
Actually an M16 thread can have 7 different pitches which are officially recognised & not 'specials'.
See here: METRIC THREAD -- EXTENDED THREAD SIZE RANGE
you mean M16 x2
