The DIN (Deutsches Institut für Normung) EIS standards and the JIS share 
a lot BUT there are more than a few gotchas in the mix. Depending on the 
thread pitch itself the root diameters and thread wall angles may be 
different. In practical use it means that you may have a M-8 bolt in JIS 
and an M-8 hole in DIN and they will not go together. Things like head 
bolts on German autos and bottom end parts are a couple of the OOPs 
areas I have run into.
