Ok, now to ask the obvious. Why should a particular country change its long held, tried and tested method of measurement? Good grief the Industrial Revolution came about with a myriad of different sizes. Some of these were often so local that moving from one county to another meant that nuts made, eg. here in Staffordshire would not fit a bolt made in Warwickshire. Yet the modern world came about despite this mix and match arena :-)
Leave things as they are, it works.
Not if you try to put a nut made in, say, France or Spain, to a bolt made in Britain :-P
It's the same problem, but on a different scale.
To be fair though an engineer would not be doing that. He/she would have the nuts and bolts supplied from one vendor and guaranteed to go together. Unlike a hobbyist engineer (such as we are) who may well have a load of tins, jars, other receptacles full of odd nuts, bolts washers etc. It is a problem for us unless we go out and buy new parts. It's a bit like trying to get a Windows program to run on Linux. We use WINE (or Crossover) and hope it will fit. Sometimes it does but sometimes it doesn't. Personally I tend to use whichever size is best suited to the purpose. Oh, think about poor plumbers... BSP, BSF, UNC, metric, imperial.... :-))) I have to make sure I get the right thread when I make a fitting for one of my rod rests (fishing) too. They are 3/8 BSF..... I think ;-) -- ============================================== I am only human, please forgive me if I make a mistake it is not deliberate. ============================================== PLEASE DON'T drink and drive it's not clever, it's just stupid.
