After 30 years of engineering and accumulating hundreds of tools, thread

diameter and pitch are similar you always have thread angle to help
distinguish types. Occam's Razor says that most threads you'll come
across in anything modern are metric so it's best to check for those
first.

Thanks for a very useful article, Dave - I've learnt quite a bit from it.
One for the FAQ?

Seconded
