Dear Cat,

    Tapping and making screw tread can be done in many sizes of tread.
    There are about 50 commercial available type of screw tread.
    Different angle, pitch tread shape etc.) I know you Americans still
    stick to the inches tap and dies, but there is much , much more to
    use in metric. First of al I need to know the inside diameter of your
    tube. 

    If we have found a correct tap than I can tell you the thickness of
    the wire on which you can use a cutting die for a perfect fit.
