In the pics, you can see each shim has been deformed around the center hole. On one, the edge of the hole has a bulge making it not flat. On the other, a small piece near the center edge has been sheared away. Is this caused by the arbor nut being too tight? Other cause? Perhaps due to the shim sitting in the arbor nut grooves and then getting pressed?

You hit the nail on the head. It’ll slip into the threads and get messed up when tightening.

No tricks, it going to happen sooner or later. There are magnetic shims that lower the chance of pinching

Infinity dado sets come with plastic shims and they don’t seem to have that problem.
You might see if they sell the shims separately.

I have been using playing cards for shims, they don’t have that problem. Each card equals 1/100”.
