Tighten it until it breaks, then back off 1/4 turn.

What do they take, 10-12 ft-lbs? Not sure.
110-120 inch-lbs

I wouldn't do it.

I would just snug the nuts up good and tight. Run the bike for a bit i.e. go for a ride and then re-snug them up after a period of cool down.
Correct me if I'm wrong but I remember reading in the instructions that as long as it's a straight extenstion then the torque is the same, It's when you step down with an adapter to a larger or smaller size that it matters, I might be wrong.

Respectfully, you are.

I used my 1/4" drive ratchet (short, 4" long handle) and tightened as tight as I could by hand.

I have a bad habit of breaking bolts off when I use a bigger tools

I wouldn't worry about torque setting on flange bolts, they're not that critical and by design are built to flex a bit anyway.

Not being a dikk, but...... You're putting what? A 3/8" stud made of hardened steel into an aluminum head, right? Finger tight from the factory, of course. Then you're putting on a steel nut and tightening it down with a 1/4" drive ratchet as tight as you can, right?

Depending on where your hand is on the drive tool (the ratchet) you could be putting on as much as 20-30 ft-lbs of torque. Depending on your own physical strength.

Those aluminum threads in the head are hanging in there on a prayer in the first place. Then a steel stud and too much torque on the nut?

I wish you the best of luck. Seriously.

Geez, overreact much?

I know how to choke up on a short ratchet, and yea, umm I know it's aluminum.

A normal socket extension does not impact the torque setting. An intermediate connection can if not at a right angle (like a box wrench where the torque wrench is at one end and the other is on the nut).

Take care,
Richard

Maybe you're a pro. Maybe you seriously know what you're doing. I know guys that have been wrenching so long, they have an incredible feel for when to tighten and when to stop. Maybe you're like them.

But a LOT of the DIYers on this forum aren't.
