I've had these nuts for 5 months now and they are already rusting and one of the top hexagons has broken off or somehow come loose. I don't know how this could have happened, I'm honestly shocked that the $50 nuts are worse than the ones I've had at the factory for 8 years. I doubt I can get another Hex or Nut and I don't know if I want to waste my time. Better choose a better brand, something coated in a different material, and nuts that aren't two-piece so they can fall apart.
