How about for centerlock rotors? Recommendation is 40 Nm.
I have a torque wrench, but not one that goes to 40 Nm and I don't have a ratchet large enough to fit over the Lockring tool. Also, I don't see much other need for having a torque wrench that goes to such high torques. Certainly I've never felt the need for one in order to install a cassette. Is this different?
These seem less finicky than the rotors with multiple bolts. Seems I should be able to wrench it down tight without being in danger of making it too loose or damaging the threads?
No?

Never had an issue with that, but some people do tighten rotors like mad and local bike shop mechanics tell me the lockrings which have teeth on the outer side which use a Shimano BB tool can require two people to get it off.
These are aluminum threads, after having to throw away a perfectly serviceable freewheel once because the cassette would simply not move, learned to be more moderate with the force.

I torque it like I do my cassettes and threaded BBs (same tool, too) : by hand, to "tight, but not put your weight behind it". Probably between 30-40 Nm.
