Durablue Lock Nut

Hey I've got a quick question. I think this is an older style Durablue lock nut, and I am missing the allen screw. Is this just a metric set screw, or an internal hex head? The pic below shows where the screw goes, and is it supposed to thread into both parts of the nut (squeezing the gap together) or only thread into the outer part (pushing gap apart)?

My assumption is that it is a set screw that only threads into the outer part (pushing the gap apart). Sorry for the poor description, but I'm sure somebody can figure it out.
Thanks,
Dustin

I think the set screw is like a 4 or 5 size allen head. It tightens the outer piece onto the inner sleeve. You torque the screw to about 20lbs in i remember right. go to durablues website for instructions.
