Bought these at my own risk to try and polish up some of the boring wheels on my Tesla 3 that were visible when the OEM hubcaps were removed. They are good quality for the price. The size and length of the thread fit perfectly. Unfortunately, the cone was smaller in diameter than the original Tesla open-ended nuts, and I estimate that the gripping area of the 60-degree beveled surface is only about 1/3 of 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.
