Maybe we differ on the definition of "crank down". I use a 10mm wrench to tighten the nuts until snug, and they don't want to jump over the little nubs on the plate.
If I only tighten them until snug, in a couple string changes they'll work loose and jump over the plate when tuning (usually the string tension alone with .11s on a Fender scale neck tuned to E standard seems to pull them crooked). They need to be cranked down very tight for me to work - hard enough to make me worry they're going to cut into the maple. Once I do that, then they work fine. I tried a bunch of lighter settings and kept ending up with the shifting issue so thought that's the way the were. Maybe there's a manufacturing defect with the plate I got or something if that's not normal, but I didn't like it - hence my comments.
