Unless you moved it a little when you flipped it over...5/16 is 9mm??

5/16 is close to 8mm

I retired several years ago from the hardware industry after 40 years. You would be surprised how many people would come in 

looking for nuts or bolts and would say I need help with a 7/16 inch nut.  So I would grab a 7/16” nut and show it to them. They would

say that’s wrong, that’s way too big. So then I would show them a 1/4” nut and they would sometimes laugh or reply I

don’t understand why it’s called a 1/4” when I’m using a 7/16” wrench.   I thought it was fun educating the public on a nut and bolt.

7/16 head 1/4 thread

1/2 head 5/16 thread

9/16 head 3/8 thread 

typically

This crap is my life in fabrication . Airplanes are all std, all motorcycles and quads are metric, and ford is mysteriously sometime metric sometimes standard. and eff the metric system. Learn your fractions  and its not a problem

still my favorite chinese tool

Lets not forget, having our own measuring system is the reason the chinese and russsians have so many problems reproducing our airplanes tanks and other weapons

I know fractional sizes way better than metric. I ask millennial kids at my work to go open the top drawer in my toolbox and get me a chrome 12pt deep 15/16, they come back in just a few moments and say WTF did you want me to get again? Sometimes I f#ck with them and ask them to get me a 41/63, the look on their face is priceless.  Most new techs don't even buy standard sized tools, I find that very odd because I use both about an equal amount.

I literally couldn't work without standard and metric sockets, chrome and impact, short and deep, 6pt and 12pt, all in 1/4, 3/8 1/2 and 3/4 drive. After 35 years they all have the nicest patina on them, I cringe when I have to get a new impact socket that is all new and black. I still have and use my Snap-on wrenches I bought literally in 1988, a lot of the chrome is worn down to the copper but dam they feel good in your hand. 

I also rely 100% on my Ingersol Titanium 3/8 and 1/2 pnuematic impacts, I never got on board the electric tool train and never will, electric tools are noisy and heavy and don't get into places my Ingersols will. I drop my Ingersols, pick them up and they still work, drop an electric tool and good luck with using it again.
