I am very special. The headtube must have been flared when I bought it and I am an impatient bad tempered over tighter. The brake kept moving so I stripped two of the mounts by over tightening the bolts so I bought a helicoil kit. Decided to do all four. Cheap nasty kit coils all pulled out so put a 5mm drill in and drilled all the way through the frame. Then went to find some bolts that are long enough to go all the way through and can't find any. I have thought about m6 helicoil but don't want to break it anymore. Hehehehe
