Well, if you need to get a new powertube, the bolt comes with it (at least with JCS). Also, theoretically, the bit of cradling on the end of the front bolt will prevent breaks.

I also noticed that the stock front bolt was very loose on powertube compared with the JCS Redhot powertube + Hexadecagon bolt. I only got it because my stock powertube broke, but I think its a good investment.
