If you're going to bring the British Standards in what about BSF (British Standard Fine) and BSW (British Standard Whitworth. Since 1908 these have been the standard Brit threads.

Before BSF & BSW in 1884 the BA (British Association) thread was introduced. Mostly in electrical applications.

Sorry to go on but when I was an apprentice in the fifties we had to learn all this stuff.  Weird how I can remember this old stuff but where did I put those stainless nuts and bolts?
