1st. of all, and it's just my opinion, this system is really ridiculous and another way to either discourage people from adjusting their own weights or, another way to nickle and dime you. I lean more towards the 2nd. option, I have seen and worked on more cues to date with this system, where people have cross threaded the bolt back in. But as for your question, buy the right tool if you insist on doing it yourself.
