I taped the nuts before putting them on the studs and the powder was still flaking from the very first install. Also, they are not centered. So when you have wheels that are as good as mine, they spin like an oval in a circle and derate your wheel's power like they did mine. Of the 24 I bought, only 18 didn't hurt. Luckily I only needed 20, but two of them rocked on a hairpin as they weren't drilled and tapped in the middle and crapped power on my wheels. Need better quality control and maybe nut OD in description. Update: I tried removing my nuts. the first time and the socket splintered making it pointless to remove the nuts. The supplier is based in China, so it will take several weeks to replace the socket. The supplier was initially willing to work with supplying a replacement socket, but unfortunately we don't have it in stock. Now I just wanted a second one. The supplier spent the whole week trying to figure out when I could expect a replacement. Keep in mind that my car is basically being held hostage until I can get that spare socket. I currently have no idea when I will get a replacement socket and hopefully the next one won't break either. The supplier gave me an ultimatum to get a replacement socket and no refund. Or refund half and not replace the outlet. As if I need an outlet to take these nuts off, but the product itself is rubbish and I definitely feel like I got my money back. When these nuts come off my car, they go to the junkyard. DO NOT BUY THIS PRODUCT.
