Probably 2.5mm and 3mm nuts and fasteners
I don't think my open end wrench sets go that low, but I do have Wiha precision nut drivers that go down to 1.5mm and Wiha micro nut driver bits that go down to 2mm. I've used the really small sizes to take apart cameras. I've been able to keep a couple nice cameras working well beyond their usual life expectancy by cleaning out dirt and grime that worked its' way into the tiny moving parts. I have used them a couple times to do microscope cleaning and repair as well.
I don't have any personal experience in the following fields, but I have also seen tiny nut drivers and wrenches advertised for sale on websites and forums that cater to radio controlled car, helicopter, and plane enthusiasts. I visit those forums occasionally because they contain members familiar with sourcing good quality small tools.

I've got a 3mm Snap-On Combination wrench. Maybe an inch and a half, two inches long. Found it in the street by my house years ago. Thought it was a toy when I first saw it. Never used it for anything but jokes.

Smallest? 4.5 mm (although I had to settle for a 7/32" socket) to remove the screws holding the crystal onto the instrument panel on a Ford Ranger.

A wrench organizers' empty slots, of course.
You can add PCs, laptops and many other 'mid' sized electronic devices to the above. As for general vehicle work I really can't remember for sure. Maybe 3/16-1/4" or 5.5-6mm.

Once when but a sprog, I was following my Uncle around the farm. I asked "What's this big green wrench for?"
"Big green nuts" was the reply.
At that moment, I was enlightened.
Years back I used some mighty small tools repairing tape decks. I used a lot of small tools working with some of the optic at work like microscopes. I've made more than a few repairs looking through a microscope. Cameras come to mind. These days it RC cars that have the small fasteners. There is a whole big world out there that uses tools for non-automotive work.

4 mm hex socket that I used on some e-torx bolts that held the electrical part of the antilock brake module on my Toyota Camry. I don't have any e-torx sockets, the hex socket I used turned the bolts.

Funny thing is that the 7/32" below it is actually 0.056mm larger.
I wonder if they're actually different?
