Is the problem that you never hit the tube, or you hit the tube, but

I'm not entirely sure. I think the problem is I hit the tube but fail
to maneuver the screw into the tube. But, the tube end's about flush
with the latch mechanism, so I'm not sure whether I'm feeling the tube
or the latch.

By the way, I again fussed it in again, so I won't have this problem
for a while anyway.
