British-American Translation Dictionary

The United States and Great Britain are two countries separated by a common language. (attributed to George Bernard Shaw)

Machinists in Great Britain and the United States frequently use different terms to refer to the same thing, and this can cause some minor confusion when these terms show up on web forums and elsewhere. I therefore present, with tongue firmly in cheek, my attempt to collect these terms in one place.

No doubt I have missed some terms or gotten some wrong, so please feel free to correct me with a comment here.

For convenience, the list is provided twice - sorted on the left by the American term, and on the right by the British term.
