You got it right on the MG studs but they ARE all "torque to stretch"
types. Tho whole idea is to stretch the stud/bolt such that the tension
in it is somewhere near the optimum point in its elasticity range. On
the "torque to yield" types they just sorta overdo it a bit. ;^) Always
seemed like a dippy idea to me.
