I installed a hundred of these in aluminum panels for a jig, and the 304 stainless holds up way better than the old zinc ones I used before. They thread in cleanly without galling, which surprised me.

The 304 stainless steel feels much more robust than the standard carbon steel inserts I've used before. They threaded perfectly into a few stripped holes in an aluminum bracket, saving me from drilling out the whole assembly.

Really cleaned up a few old bolt holes in my project car. The 304 stainless feels solid and the threads catch perfectly. I've got a whole pack left for future repairs, which is great.
