Alternatively google will throw up loads of tables if you search for "Metric thread data"," BA Thread Data" and "Whitworth thread data" all showing major diameter and minor diameter.
the bible of course is Machinery’s? Handbook (I’m away from my copy so can’t quote current ed but quite a bit more expensive that Harold’s book (well thumbed in my workshop)
I always recommend Motalias website, it contains a good number of thread charts which can be printed out and may well have the data you require. They also have a lot of goodies for motorcycles.**LINK**
Tubal Cain's "Drills Taps & Dies". No 12 in the Workshop Practice series.
Everything you need to know about threading and drilling. Read it from cover to cover. Make photocopies of the charts, laminate them and put them in the workshop.
