I have heard of an anti-scalding device that can just screw into a
kitchen
faucet. If this device exist, I could use it. Does anyone know of a web
source where I could perhaps find one?

I see someone has already suggested turning down the water heater.

Actually, my water comes out at 138F. Which is exactly the perfect temp to
run all of my plumbing needs with the number of people in the house. I do
not consider anything a real scalding risk until it gets a little higher in
temp. I just wanted something that would keep the water at 120F or so, at
just that ONE place.

Personally, I do not like setting the water heater down on 120F. I bought
the house, I bought the heater, and damn it, I'm going to take my hot
showers...

I can sympathize with *that*. :-)

However, after I posted, I looked up some references to "scalding." It
seemed highly unlikely (to me) that one could be scalded by water at
120F, which is summer air temperature in some dismal locations.
However, evidently this *is* possible with skin exposure over several
minutes. A shorter time at 140F. Tapwater scalding is primarily a
hazard for young children/babies and the elderly.

As to the original question, searching on

scald temperature

turned up a number of references to plumbing gadgets/valves suitable
for your purpose. Just don't fall asleep in the shower. :-)
