Its metric. I bought it off Ebay a while back because the price was
right, but I can't find the descriptive number anywhere now. I would like
to get some more the same size, but longer for an application, but for the
life of me I can't recall the screw number to look for. Its 6mm diameter
and the pitch is about 1mm.

After much search I am beginning to think this is a fairly rare size ball
screw.
