These nuts rusted after the first ride on the salty road and have since decayed. They have only been removed once so not too worn to be rusty. Also the strength of the steel seems questionable - two of these about to cross the threads and didn't show enough resistance to avoid damage on the first two turns, and doing this by hand with my fingers, I haven't even broken the keys yet. At least they're cheap, but I'll definitely get a better set elsewhere.
