3mm obviously very fine thread pitch. I carry extras that I bought at ACE.
Sorry to be that guy, but do a search in the 80 section for "trailgear nut" and you'll find the thread that has it. That's how I found it an followed it to get them for mine.
The only caveat I'll add is that I really don't like Allen-head screws because invariably the tiny Allen head strips out in the screw, and there is nothing left to get hold of. If I do it again, I will replace them with either a #2 Phillips head or a straight cut screwdriver head (slotted) You cannot "torque" those tiny little screws. and when the Allen wrench slips in it, there's no grabbing it. I could MAYBE see using a Torx version.
Or just take the nut to the hardware store, like we would have in the old days, to determine thread pitch.

+1 ON Torx head, much greater gripping surface.

No issues to date?
At 27 cents a throw retail, you'd think TG could sort this one out
Nope all good
Tiny torque for tiny screws and you should not have a problem striping the wrenching hex out. These screws are messed with rarely anyway but if you wanted to, you could go in with new ones every time.

One more Q: since TG nut replaces BOTH stock nuts, do I torque it to the inner nut spec, or the outer preload, back off, lighter retorque? I suspect the latter, but it can’t hurt to consult the Brain Trust...
M8x1.25 threads in the axle end. Torque the nut to 25ftlbs and lock it down. Some members go 30-35ftlbs but 25 is working for me on 37’s. If your spindle, bearing housing/hub and /or wheel bearings are warn out, retaining bearing preload will be impossible.

No preload first, or would that be pointless?
The 25ftlbs is the preload.
I would torque the nut, rotate the hub each way a few times, then retorque.
I also whack the hub hard with a dead blow hammer a few times before retorque to be sure all bearings are seated fully

Torque the nut WHILE you are rotating the hub.
