I am a bit tentative with torquing things on bicycles like cassette lock rings. I don’t use a torque wrench on cassette lock rings but I bet that I rarely get up to 40 nm on these delicate little things.
But as I am only working on my own bikes (generally) I have the luxury of being able to check its tightness again - maybe after a ride or 2.
And yes, it always needs a bit more tightness !!!
In the “old days” when we were using square taper crank spindles, it was accepted that you needed to periodically tighten up the crank bolts.
The professional bike mechanic of course does not have the “luxury” of being able to get away with “probably sufficient” torque/tightness on many threaded bicycle components.
He/She has to use plenty of force- because it cannot be assumed that the owner is going to periodically check the tightness of things.
Speaking from personal experience, it’s not a great moment when you’re riding along a bush road and the crank goes loose, and then falls off.
LOL. My bad.
