Hi Everyone
Thank you for all your replies. I find the info very interesting. I was aware that is a slight difference between 'modern' nuts and the originals, but I never thought about the two wars having an influence on it, but that makes perfect sense. I just assumed it was due to poor quality manufacturing (attention to detail) as is the case with many products produced today. I have recently purchased an old book (from the 1930's) that is dedicated to screw threads and systems. I've yet to read in great detail but I've found the attached extract. It doesn't add much to the discussion but I thought it would be of interest.
I'll go and measure the 'used' original I have, I'm sure it will correlate with the information discussed here.
John - Thank you for the link, I've contacted this company now and it would appear they can supply me with some and they seem to be produced like the originals.
Stuart - Thanks for the info on the alternatives, its useful to know and I understand your concerns Chris. I was only considering close alternatives as I was struggling to find any being produced like the originals. I don't intend to use these for a 'tolerance critical purpose' or mechanical part. I'll always try and endeavour to find the correct like for like nominal replacement.
Thanks again
Matthew
