Yes, as a matter of fact the Alden wrenches are sized like normal
wrenches. The ones that we made with the grad students were fixed jaw.
The pivoting clamp lower jaw is an improvement to the concept. I don't
have any in my tool box.

really do work!
Do they have size flexibility? If they actually clamp on as you apply
pressure, you would think they might work on near sized metrics as well.
However, can you get a socket with a wobble extension in there? A
wobble extension will get you a more torque ability than a wrench.
You can find them at Harbor Freight. A great addition to the tool box.
I can’t get the socket itself on, so the wobble won’t help. It might
work with a very shallow socket and then I would’t need the wobble as
the center is accessible.

I was at the boat yesterday and tried to take the heat exchanger off
the engine (Universal M4-30) so I could refurbish the seals and make
sure it is clean
(http://www.pbase.com/mainecruising/heat_exchanger). One bolt came
off easily but the one on the starboard side is a challenge. I
cannot get a socket on it because something from the engine or
transmission is partially blocking frontal access. I found my
wrench selection on board is less than adequate and I need to
upgrade. I tried with a short 1/2" open end wrench and was able to
get it on, but could not budge the bolt. I left it sprayed with
penetrant hoping that will loosen it.
I looked at other wrench types to see what would be useful in this
situation and came upon this ratcheting wrench I had not seen before:

It looks like something useful to have on the boat as the clamping
action should work on both metric and SAE, it is stainless and it
ratchets. Has anyone tried something like this?
The other type I am considering is the flex head ratcheting wrenches:
