Purchased to replace the original nuts which the dealer ruined. It looks like the dealer checked the wheel torque with an impact gun or 12 point socket. The surface cracked and they rusted immediately. These are certainly not the cheapest nuts, but the quality is very high and they are made in the USA. Revain offered the best available price at the time of purchase. Edit: After 5 years of daily continuous driver use incl. winter, tire changes, brake work, car wash etc. they still look like new.
