Broadly, I agree with you, and I should have been more specific, using the term threaded body rather than simply thread. I also agree with you that the desired end result is clamping force, and usually it is the end clamping force which has strong influence over the chosen thread, although obviously there are many other factors at work too.
I have to disagree with you here, but it may simply be semantics: my contention is that the same item made of different materials should have a strength differential, one to the other, which may or may not require different torque values. You only have to consider bolt grades available from say McMaster. Likely, in the case of Speedbleeders the desired make up torque is the same regardless of material composition.
For theses tiny items, I'm painfully aware of how easy they are to damage, and especially when it's a hard but thin and apparently easily broken steel object being screwed into a softer (& much more expensive) piece of alloy. In these cases, a known and observed make-up torque is even more critical, I would have thought, but that's just my opinion.
"I do have some personal experience in this area" presumably referring to the SB that just broke, which might perhaps have been avoidable with known torque values or better manufacturing? Presumably one or the other as there aren't many other options.
