Are you talking about the little tool rack that's mounted on the tailstock?I looked over my 1216 - The only screw I found that looks like that is on the little tool rack that is mounted on the front of the lathe, on the right side. There are actually 2 screws holding that little rack in place.
Unfortunately it's not from there, both screws are there.Sorry for the delayed response. Yes, that is the tool rack I am talking about.
