    through fear of putting people off using him, im not going to say where I got these from

    neither, am I going to suggest its a mistake on his behalf (even though ive checked my order)

    see attached photo

    the screw on the right, is meant to be my Z screw & 1605 and the one on the left is meant to be my Y screw & 1610

    correct me if im wrong, but arent both 5mm pitch?

    It's probably a two start screw - I remember Chai sold Jazz some twin start 10mm pitch screws, but fortunately he noticed before sending them back! Just spin the nut one revolution and see how far it goes, or look at the thread at one end and see if you can see one or two 'ends' to the thread.

    In fact - just from looking at the photo the screw must be 10mm pitch since the helix angle looks about twice what it is on the 5mm pitch screw beside it.

    I had the same panic after I spent hours unwrapping the things. Think mine have them marked on the ball nuts as to what they are.
