Wheel bearing damage caused by once tightened wheel bearing screw?

Hello, I changed the wheel bearings at my Skoda Octavia on the rear axle the other day. My brother (non-handler) helped me and I put on him to set the torque wrench to 180Nm to advance the wheel bearing screw (picture Pos. 8). Stupid as I am, I didn’t check the whole thing anymore and in the end I tightened the screws with 180 lbf*ft, which corresponds to 250Nm (the torque shlussel has two scales) and afterwards again nice 180 After we cleaned up at the end, I noticed that. So screws again completely dissolved and properly tightened. The car did not drive a meter in the meantime.I am absolutely aware that screws have a tensile strength and a yield limit, and that the elastic deformation also eventually passes into a plastic one and the screw is then either scrap or not so good. Actually question: Does this put the bearing sometimes are I thinking that they could put that away, or maybe not. Supposedly, the 70Nm make an eighth turn of too much pretension, then that would be ‘only’ two tenths with a thread rise of 1.5mm? Bearings are from SKF. What do you think?
