3 out of 3 precut nuts I received were super high, and had way too much material left on top resulting in deep slots. Very safe.
Nothing sandpaper and some extra time couldn't fix. I tweak both anyway, so it was just a matter of needing alot more time to complete the job.
The radius was good on all of them though.
I guess it's not that big of a deal if I keep ordering them, right?
