I am looking for a set of nut drivers for 00-90 - 2-56 nuts. In particular something with a long shank as narrow as can be in relation to each size. I already have the short finger twist kind, but, their shank gets too fat, if you understand what I mean.

Check out a jeweler's or a watchmaker's supply house.
How about Micro Mart?

Or even Micro Mark....
Nut drivers are sold by the hex size, not the screw size. The most recent set I purchased was from Wiha. They are either made in Germany or USA. No Chinese junk. Most nut drivers have a little taper on the inside to help them get started. But when working with very thin hex heads, like is sometime found on prewar crank pin screws, this taper is a problem. So I took my nut drivers to an automotive machine shop and had then grind just a little off the ends to get rid of the taper. That was a real improvement for what I do. Sometimes I less the small nuts up inside the shaft. I have been thinking about driving a plastic rod inside the shaft to limit how far up things can go. However, this would prevent the nut driver from working on nuts on long studs, like is sometime found in electrical work. So this is still in the thinking stage.
I grind the ends myself for the drivers to they will handle thin nuts. I have the Wiha sets in metric and SAW. The other thing I've done to several is to grind the outside some where they had to fit into tight places. The walls are way thicker than they need to be for what we do with them.
You can have it from Amazon with free shipping for the same price.

Thank you, but that is too thick.
I've got a couple Wiha sets and they have fit everything I've used them on without extra grinding.
I had to flatten the rounded edges on some of them for the very skinny rod screws on some brass locomotives.

Square ends insure all of the wrench is covering the nut. Even if some of the wrench engages you risk rounding off the top of the hex. The advantage of the rounded ends, it makes it easier to go over the nut but assuming 8 second pit stops is not your goal the flat ends are better.

I had to machine down several tools for better fitment,….a good example is the 5mm head on the MTH eccentrics ,….the head of that fastener can burry itself in the eccentric ….the rounded end of every tool made will either not grab, or grab poorly and the risk of chewing it up to unsightly is too great,…if I do machine down a tool, I try to use one made out of Chinesium…..the softest tool steel on earth,…😉

My 5mm driver is one of the ones that has been flattened for a better grip.
I’m still curious as to what Jim is looking for …..not sure what he’s after even exists,….maybe if Jim has a pic, or just jot it down on a piece of paper and snap a photo, we can try & help,…

Jim, does this tool set from Moody fit the bill?….to be sure some of the wall could be skinned down on a lathe, as long as you’re not trying to make fasteners 3 grunt tight, ….99.9% of the fasteners we encounter in this hobby ain’t got a grade rating anyways, so if we sneeze wrong while tightening, to be sure we’ll ring them off,…😉

Here's one:

You might have to grind the outside if there is a clearance issue.
There is another on Amazon and it is a Klein, which still makes the majority of their tools in the US. Since the apparent dimension for a common 2-56 nut is 3/16 inch. Look that one up, when I posted the link here, it also opened my amazon account, so deleted it.
Amazon gets mixed reactions from folks sometimes, but it is hard to circumvent them and try to buy from a distributor when it takes them over a week to process your order, when the same item is offered on Amazon with next day delivery. Also, you still run into companies that have that exotic thing you want, and you have to request a quote, and then it turns out you have to buy 100 of them or no sale.

Pat, That appears to be what I am looking for. Since most of what I have been doing is working with plastic, I just need to cinch things together. The main thing is having something thin enough in order to get into tight spots. Where can I find this set? They haven't shown up on any of my searchs.
