Bought at my own risk to try and fix the boring wheels on my Tesla 3 that came out after the factory hubcaps were removed. They are good quality for the price. The size and length of the thread fit perfectly. Unfortunately, the cone was a smaller diameter than the original Tesla open-ended nuts, and I estimate the 60 degree beveled holding surface is only about 1/3 the original. I didn't find it safe to use them with a smaller mating range and will look for a better match. Too bad, there is nothing wrong with these nuts at all. I should have spent a little more time comparing all the sizes required for the 19" Tesla 3 hubs.
