I think that it is good if the height of the part to be sandwiched is as high as 15 to 20 mm. Our company manufactures and installs an auxiliary plate. In addition, although we have made it possible to turn the steering wheel with a small amount of force using a pipe etc. at the time of tightening, because the breakage occurred on the handle side surface, we installed "reinforcing plate" that surrounds the circumference . I think that it is easy to handle because measures like this can also be attached.
