With aluminum, you have the dissimilar metal galvanic corrosion that can be lessened by using a proper goo. The failure mode is that the plate strips out and you can use a helicoil to repair it.

With stainless steel, the failure risk is less but the penalty is more severe. Galling of the threads can happen from over-tightening, overheating (spinning the bolt too fast with a tool), or repeat motion. The failure mode for a stainless bolt in a stainless plate is for the bolt to shear.

Personally, I would rather have to repair a stripped plate than figure out how to fish out and repair a galled and sheared bolt.


Mine broke in the aluminum plate because of corrosion ,then the plate broke loose from the laminate.Fun Times.
