I think I'm a true engineer. My bachelor's is in mathematics, my master's is in systems engineering. I've been working almost 30 years in various engineering and R&D disciplines.
Get yourself a Machinery Handbook. All of the calculations for threads and material strength are explained there. The only thing you need to know after that, are the specific parameters of the materials that you're working with. The calculations are simple. Even estimations, without specific use cases, are sufficient to arrive at a basic understanding.
We won't get a 100% conclusive answer (regarding full effects of torque vs accuracy - or whatever) without someone's empirical data, but you'll get enough of data to see that the physical properties of the material are near the bottom of the limit, and don't put the system in any sort of danger.
Beyond that, we're operating in anecdotal territory, and really shouldn't be dying on any hills. That's the domain of those who have actually put in the work. Don't defend ideas that you can't prove.
