Timothy ★★★★★

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.

Kevin ★★★★★

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.

Grace W. ★★★★★

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.
