Just waterjet a new tool with all of the specs you need out of high strength steel. Or grind down the 13mm wrench to be skinny and then put a rubberized coating on it to fill in the small gaps you are having problems with. Surely you can come up with a mastermind solution for this job! haha Also you might be able to use the aluminum anodized open end wrenches that are used for AN fittings and just grind them down if their profile is too fat.
or maybe these?
Amazing deals on this 15Pc Sae Service Wrench Set at Harbor Freight. Quality tools & low prices.

The wrench doesn't need to be skinny. There's all the space in the world behind it. The problem is the load is only spread over 2.4mm. Rubberized coating will not hold up. Aluminum will not hold up.
This sounds exactly like a pedal wrench

The closed end of that pedal wrench is exactly what I need, just 13mm (or ideally 12.9mm) flat to flat. Open end wrenches deflect too much for the torque.
how much force are you applying? or What reason would steel not hold up?
Not quanitified, but I'll say a lot. First problem is a lot of loctite, and second problem is a bunch of heat cycles. Even once it's broken loose, it take dozens of foot-pounds to twist it out.
Basic thin wrench not good ?
No, thickness is not an issue as there is plenty of space, so a larger wrench would be fine for greater stiffness.
I'm sure you've tried it already, but that looks like a 1/2" wrench would work better... If 1/2" is too small, get a Harbor Freight Pittsburg wrench so it spreads a bit...
Unfortunately a 1/2" wrench is about 5 thou too small.
Those genius Germans didn’t provide you with the tools you need to service the tools you sell? Throw this back over the wall into their (Patrick’s) lap and let them figure it out. “Sorry, we can’t do anymore repairs because we don’t have appropriate tooling and we’re damaging the customers’ products and there’s no off-the-shelf solution commercially available.” “And the customers are angry” - gotta throw that in there. Nothing you come up with will be as good as a German could do it.
You know too much of the situation. Hush.
Get ready for my insanely accurate blue print design.
I assume you need an actual socket, not a shop made one?
Typical shallow, chrome socket, appropriate diameter. Cut down throug the big end opening correct width, + 1/8" on each side, weld 1/8" flat stock across both sides of the opening, done.

The 1/8" stock would be too soft in the long run, however, this does give me an idea. Just take a socket and turn it down and mill a 12.9mm flat in the body where it's broached for the drive. I don't know how hard that would be, but its at least got a shot.
Same idea as the Knipex Pliers Wrench mentioned earlier in this thread. Basically what we're doing now, but not really the right tool for the job in the long run.
I feel like in the time this thread has run, a tool could have been made.
#facts
Does it even need to be a handle style tool?
I'm of the opinion that a socket style tool that is a cylinder with a slot cut out of the bottom and 3/8" square head for a ratchet would be way mo betta.
A 13mm socket w/ the sides ground down via dremmel would work too.
Yes and no, but a handle style tool will work much better. The handle style tool keeps all torque flat and inline with the head of the bolt. Adding a sock or any extension inevitably translates into a compound load that will cause the tool to slip because the head is too damn short.
I don't think anyone makes a 13mm pedal wrench, They're all pretty much 15 or 17mm... Now a Cone wrench, maybe....
The standard of the bike industry, and essential for hub bearing adjustment and replacement.

Wrench thickness is not an issue, so the cone wrench would just be less strong than standard wrench. But this is the kind of oddball stuff I was hoping would come from this thread. Somewhere out there is probably the thing I need, but its for some other weird application.
The core problem is the head of this bolt is too shallow, and only a 2point fastener instead of a simple damn hex head.
