Toolbox Error?

Can somebody please confirm what I believe to be an error in the Toolbox database?

I am referring to Hex Socket Head Shoulder Screws - BS4168-7. I do not have a copy of this spec, but all the checks that I have done online with suppliers and manufacturers have raised the following anomoly.

Tollbox shows M5 screws having a shoulder diameter of 6.5mm whereas all the details that I can find specify the diameter as 6.0mm.

As I am about to use one of these screws, it is important that this is confirmed.

EDIT: It would also appear the the ANSI B 18.3.3M info is incorrect.
