Worked like a charm for me and my rx8 which I bought with lock nuts that didn't have a wrench. I used this product along with a shock cord to wear and they came off immediately. It would be difficult without a percussion pistol. It would be 5 stars but the nuts get stuck in the socket. So you'll have to use locking pliers and run it back onto the machine to unzip it. Because of this, you may need to purchase more than 1.
