    It's an M3 grub screw. Do you want the outer or the inner one?

    Have a look at this page http://www.modelfixings.co.uk/stainless_grub_screws.htm

    The inner one is the longer one. I think 4mm and 8mm will be enough.

    If it's the inner, long one I've got a spare one knocking around somewhere. Drop me a pm with your address and I'll have a dig and see if I can find it.
    I'll pop it in the post during the week.
