threaded post mount on forks

I recently purchased a second hand bike and it came with a Hayes 9" rotor on the front, having read up on it I decided I didn't think it sensible to run it on a Fox Float R fork so I decided to put the standard 7" rotor back on, I was just tightening the bolt and it has threaded :( I was only nipping it tight which is a pain as well

So my question is what is my best bet as a fix?

My ideas are either use a larger diameter bolt or try and get some aluminium solder and try and repair the original size mount.

Any ideas would be much appreciated

    Try a slightly longer bolt, there more be more thread further down the mount

    Or get it helicoiled

    sorry you have stripped the threads not threaded it.

    you may be able to get it helicoiled if there is enough metal. otherwise new lowers time.

    You're right it's stripped, i was having a mind blank :oops:

    Has anyone used a Helicoil then, would they work if the bolt was regularly used?

    Some people drill and tap to M8 , but this is a permanent thing as you need to drill out the brake caliper holes which cant be fixed later. Ideally, you should helicoil if possible.

    I think the Helicoil looks to be the best bet, any idea who does such a thing?

    I thought this stuff may be a possibility clicky

    many LBS's or any engineers shop.

    and I would not use it on a fork.
