Anti-Rattle Device and Hitch Lock that Works with the PortablePET Twistep

I am interested in ordering the Twistep for my car. I have already purchased the Quietride anti-rattle hitch lock from you in the past. I was wonder if the quietride hitch bolt will work with the threads in the twistep drawbar. Neither quietride or twisted specify bolt diameter or thread size. Since you have both, can you tell me if they are compatible.
