    If the pitch is metric the leadscrew is Trapazoidal(Trapazoidal is the metric version of Acme)
    Not all the pitches are show on the charts i had a look @. I was looking for data for turning an M8 x 2 leadscrew and couldn't find it,fortunatelly i have a tap and will make the nut first and leadscrew to suit.

    Many Thanks Mick.

    I have not fitted backlash nuts yet, but this info will be valuable for the future.

    Regards

    Hi Ray,
    Why not replacing the leadscrew all together with a known diameter / pitch?
    Trapezoidal screws are fairly cheap these days.
