The aluminum stripped before they were even screwed down all the way. They should have been steel or titanium. I had to finish with my fingers and I hope it holds. Not only that but the old studs were on so tight I have to use pliers to get them off dinging my new ti pocket clip in the process. It was overall not a very good experience but I am pleased with how they look. Just hope I like it forever cuz they aren’t coming back off with a torx bit.
