I have been looking at http://www.tribology-abc.com/calculators/metric-iso.htm And see plenty of scope for confusion, but I am not sure that the diagram is actually right. It seems to indicate that the nominal diameter is to the centre of the crest-rounding, so the actual OD is bigger than the nominal size, whereas every bolt I have ever measured is less than the nominal diameter. -- atp ------------------------------------------------------------------------------ _______________________________________________ Emc-users mailing list [email protected] https://lists.sourceforge.net/lists/listinfo/emc-users
