  1. What gauge is the threads on a 2005 KH20 frame? And is there a tool for
    it. Need to get the thread back from the paint.

  2. You're likely thinking of a tap. While a tap can be used to clean a
    thread, I believe it should only be used as a last resort. By design,
    a tap removes metal in the process of threading... even though your KH
    is already threaded you may end up removing more than just paint,
    leaving the threads weaker than they were before.

    If you haven't already tried solvents, wire brushes, etc., to clean the
    threads, I'd suggest you give those a go before resorting to a tap.
    If you're worried about damaging surfaces that you want to stay
    painted, you can coat them with wax / paraffin before applying the
    solvent.

    If you do want to go with a tap, simply bring a screw from your KH to
    your local hardware store and ask them if they can measure the threads
    on it and recommend a suitable tap. You'll also need to get a tap
    wrench... together the two parts should be $10-15 USD. Before using
    the tap, however, I suggest you do a little research on how to use it
    properly. It looks easy to use, but once you mess up with a tap it's
    very, very hard to fix the mess.

  4. I would do it with a tap, but you will need to be careful that the tap
    goes into the existing thread and doesn't take out more metal, or
    you'll [censored] the thread up like maestro said. The powder coat will be
    much softer than the metal so it shouldn't be too difficult to make
    sure the tap goes into the thread. If the coating is just around the
    ends of the thread, rather than going right into it, you might be able
    to poke it away with a sharp pointy thing rather than having to use a
    tap, but mind you don't damage the thread (it's aluminium right?)

  5. Grease the threads, thread the bolt in a little, and just crank on it
    with an allen wrench till it clears the threads.

  6. Use a tap. Go for a cleaning tap (the one without the big taper on it).
    This is what they are designed for, a bolt is as likly to damage the
    thread as fix it.

    Do be careful when doing it to make sure it is going in square though.

    The thread size is a standard M6 I believe. One of the most common
    sizes available... I think it is M6x0.8 from memory, but do check this
    first.
