A 9/16" wrench is for a 3/8" bolt which should not be 120 ft-lbs - 120 in-lbs would be more like it but that does seem a little light.
I am not familiar with the application but is this a light torque load where it is locked some other way and they are more for shear - if so 120 in-lb would be where I would put them.
Do you see what felt like it was stripping?
I felt the stripping feel but could not see any stripping damage.
