I somehow lost the knurled nut. While I don't technically need it, my belt tends to click when I move. I'm in the U.S. and don't really want to pay the shipping again from the U.K. Does anyone know of a reliable replacement nut? I saw one guy who had a tamper proof nut, and it looked like this, but I have no idea if it would work. Can anyone please help? https://www.amazon.com/iJDMTOY-Stai...ywords=8mm+security+nut&qid=1713959914&sr=8-5
