Nope. Guess again. A 5/16 bolt uses a 1/2 inch wrench. A 3/8" bolt
takes a 9/16" wrench. A 7/16 bolt takes a 5/8" wrench, and a 1/2 inch
bolt takes an 11/16 inch wrench. 9/16 uses 3/4, just off the top of my
The issue with METRIC is there are several "standards" Japanese (JAS?)
standard uses 10mm on 6mm bolts, 12mm on 8, and 14mm on 10 and 17mm on
American Metric uses 11mm on 6, 13mm on 8, 15mm on 10 and 18? on 10.
European stuff can be either, from what I remember.(ISO)

So how come my damn tin shed uses nuts and bolts that take an 11/32"
wrench? Which NONE of my several sets of sockets or nutdrivers or box

for their deep-discount sets.)
Ha! Check some other tool Mfgs, like Snap-On, Mac and all those, and
you'll find Craftsman is a pretty good deal.
So if you work with a lot of 11/32" stuff, go get a socket or two...
perhaps a 1/4" drive 6pt standard and deep (Being so small, I'm not so
sure they're even made in 3/8" drive). An 11/32" combination wrench,
and/or long box end that includes that size, and your set up for most
anything. They won't run you much, add them to your set, and with
minimal care will out last you and the shed many times over.
Even though the shed may require a lot of 11/32" stuff, all in all it's
really not a very common size nationwide. 1/4" and 5/16" by far surpass
it as the head size for smaller screw wrench sizes.
PS, All this 11/16" stuff is hex head right? If not, get 8pt sockets.
Last I looked, a couple of years ago now, Craftsman still carried them.
Some of the SAE sized hardware from China is being manufactured from
metric hex stock in the case of nuts: I have some 1/4-20 nuts with 10
mm flats. Normally these would be 7/16" or 11 mm. The plating is
pretty good, though. And they were quite low priced.
Standard size nut for #8-32 machine screw nut. Part of any decent
1/4" drive socket set or nutdriver set. Or you can always use a 4"
crescent wrench. Or like a friend of mine does - he drives them with
his little electric dril - 3 jaw chucks work great on hex nuts.
I don't get how someone can't understand that why an M10 bolt doesn't use a 10mm wrench!!!
Did you ever saw a bolt that had a same size head as the shaft??? Ex:1/2" bolt (shaft) with a 1/2" head! Man I think you need to stop turning wrenches before you kill someone!
There are two dimensions at work here:
1) the bolt shaft, and
2) the bolt head.
The "10mm" refers to the diameter of the /shaft/ of the bolt.
The "17mm" refers to the flat-to-flat dimension of /head/ of the bolt.
You're a Communist, aren't you. Your explanation sounds
reasonsable, just like one a Communist would use.
And you sound helpful, just like a Communiist would be, until you
But I'm not going to fall for that.
Maybe you're a Socialist. Everything I said about Communists applies
to them too.
