They have a pressure sensitive, glue-like coating on the outside of the insert threads that adheres to the threads they are installed into. After it sets up, you have stainless threads encased in your (in this case) aluminum part. Pretty much bullet proof.
Even the standard non-adhesive inserts would be better than a stainless screw in an aluminum part.
Thanks. Brad.

I could be remembering something wrong, but I could swear I remember installing pre-adhesive HeliCoil inserts in the past, but now, I am unable to find them. I could have been KeenSerts, which I'm not really a fan of.
Still.... I'd prefer a non-adhesive HeliCoil over a stainless screw in aluminum. If you ever have to remove them, especially if they've been there awhile, you may end up with a real problem. I had to run a form tap into my exhaust manifold where the shifter cable bellcrank bracket attaches. If I ever have to remove it again, I may be forced to install a HeliCoil in it, as the threads are all but gone after I just about ripped them out getting the screw out. It's just a bad practice.
Thanks. Brad.
