Slightly Damaged Steerer Tube Threads

In overhauling the headset, I noticed this damage to the threads of the steerer tube:



It makes the nuts relatively hard to turn.

How do you think that happened? Should I try to fix it? If so how?

Thanks,

It looks like the keyed washer between the locknut and cone was turned when it was tightened. I would take a needle file and dress the threads in that area a little so the cone and the nut spin on easily. Then, when re-tightening the headset, I would use *two* wrenches and not rely on the keyed washer to keep the cone from turning.

Edit- actually it looks like it was done while loosening. Which is a better situation. Still use two wrenches when tightening, should use two when taking it apart, too.

If your LBS has a fork thread die, they can chase the threads with it and clean up the damage. It shouldn't take more than a couple minutes if you bring the bare fork in.
