Why do lug nuts not loosen threaded studs when removed if the torque on them is much higher than on the stud?

Question

100ft/lb vs. 30ft/lb for the studs.

Threadlock is said to be optional.

Is it because the torque required to loosen the lug nut is acting upon the wheel not the stud? And the only moment applied to the stud is friction between the threads? (which is low)

​

Answer 1

The thread area on a nut is much smaller than on the long threads of a stud. So with different torques, the looser threads can be “stronger” because they have a larger area.
