sry to bring up old thread, but i had to stickle on this one
9mm = 3/4' btw


it is one of the few "exact" measures between metric ind in.!

actually 19mm is only .748". good for socket purposes, but not exact.
theres lots of 'almosts' like that which are really close to fractional sizes but no cigarillo!!
