Re: Grand Scenic roof bar bolts - sizing problem!

Eventually I gave up and just took the bolt out again, and the thread on the bolt seemed to have been damaged slightly by my efforts. The bolts look like they're the right size, but it's as if the thread on them doesn't fit with the thread on the hexagonal fix point nuts.

Any ideas? All help would be greatly appreciated.
Generically, there are two options.
Either the bolts do not match the thread on the nuts (go to a decent hardware supplier, and try bolts to get some that do fit) or the nuts have some rust in them (use a thread cutter to clean the threads, but be sure you are using the right size tap before you start!!! )
