Fastener Standards

This has been bugging me for some time.
The nuts I have used since drawing on the board have been to BS3692/DIN934. This is also a standard listed in Machinery's Handbook.
Toolbox does not have these, anyone know why? They are straight forward nuts but the o/all height is not the same as the thread size as in some other standards,
has no collar or flange.

I have come to notice that
BSI / DIN / ISO contain a series of nuts which in fact are all the same, they just have a different code attached to them depending on which country uses them
eg BSI BS EN 24034 = DIN EN24034 = ISO 4034.

Correct me if I'm wrong. But in an attempt to get a std nut w/out collar/flange/prev.torque etc. I have changed the standards and ended up with the same nut.
