Good screws
Would RecommendGood screws. I did have a few heads strip out when I had to remove them and re-install them. But that could have been me since I was driving them at an angle but didn't know the exact angle when I pulled them out. The Torx bit supplied gets a little worn by the end of the box. One made out of slightly harder steel would be better.
