You may want to consider this. If the hardware came with nylon locking nuts, use regular nuts and snug them down, not torqued, until you are sure it's all correct and you won't be taking apart. Then, one at a time, replace with the locking nuts. Those nuts lose some of their locking ability after just one cycle. I would do that with anything other than lock washers, including if they are deformed thread lock nuts.
