If you are looking for quality nuts, this is not it! During installation, the paint peeled off the edges of each nut. An appropriately sized socket and ratchet were used to install, so this was not due to improper installation. Also, 4 of the 20 nuts were cross-threaded when I installed them. I fully tightened each of them before using the ratchet, so I don't understand why they cross over and don't work properly. The only thing I saw that could be causing this problem was that the threads of all the nuts were covered in paint. This caused problems when mounting all the nuts. I would not recommend these at all!
