Got them last August (all but 4 because I installed a set of Gorilla wheel locks at the same time). They were hand installed and then tightened to specification. They are already beginning to rust and chip at the edges. Some of them weren't even drilled right through (I should have just put them back in from the start when I found out during installation, but a couple barely unscrewed so I used them anyway). I would NEVER recommend them. Just spend the extra money on real black nuts (Toyota P/N PT076-60200-02). Those Orion nuts went in the trash where they belong. I would give them zero stars if I could.
