I am NOT going to make a ricer joker, nor am I going to talk about how 14mm is somewhere between 1/2" and 9/16". The whole thing just makes me hate the metric system even more.
Too late --- she's already been gone a week. Seems one of the guys at the construction project down the street had some Snap-On tools a relative left him. So far I've tried the 9/16" box end and it seems to work real well ---- so maybe I got a pretty good deal.
