You can use a regular 10mm bolt just like came out of it. Again I'll try the picture. You'll have to excuse the primitive nature I just whipped it up really quick. See how much smaller the hole you will drill into the broken off bolt is than the actual bolt. You'll just drill a small hole in the center of the bolt (be sure it's in the center) and then the back-out tool will screw into the small hole and take the entire bolt out without ruining the original bolt hole. That way you can just screw a new one back in. Hope that's clearer. I really gotta go now. :thumbsup
