Thanks,
I was looking up some of the types of nuts we buy (like
M8) and I found that the 8 mm thick cost 14 � a piece and the 6.5 mm is only
about 2.7 �. We may be buying something special or more then what we
need. I need to research this further. But thanks for the lead, you
may have saved me days of research.
