Craftsman makes metric wrenches as well; why not use a real 16mm? +++++++++++++++++++++ I'm sure you're right, John about availability. It's sort of about convenience: the common metric sets now come with 15 and 17 mm sockets (or open end, or closed end), but no 16. So I often don't have a 16 at hand. I've never bothered to buy one, because there's always a 5/8 around, and it has never failed to fit. But, to each his own. It might be a 0.125 mm difference, but, as Fred Rednor observed, it's only 0.005" - a few thousandth. I'm glad my wrenches aren't that precise. :-)
