The taper has been pushed down and is no longer 90 degrees at the contact area. But that's ok. I have the other set of good holes. I'm now wondering if the baseplate of the hub is no longer flat. I'll check that later.
Yes, all sorts of bad things happen when you have wrong mating parts coming together at such forces.

But, consider the loads. A 1/2 bolt of even dubious heat treat can hold, let's say, 10,000 pounds. That's 5 tons! Now, crank 5 of those bolts on and make it 50,000 pounds! Now, put your hub in a press and press down with 5 tons (or 25 tons) and see what you do. Remember that little lady with stilettos?

Jamo is looking better all the time.

ps. Isn't your "other set of good holes" for a different bolt pattern???
