Take a guess on this one. Wrongly installed coupling?

Can anybody confirm the correctness of the outside screw. I don't remember any stocks I have owned having this outer screw for the stock latch?

I probably misunderstood the question.

From picture #9 (copied here), I did not see anything wrong with the cover latch or latch screw. The latch is single milled piece with button, screw installation hole and spring integrated together. As long as it's installed on the body via that latch screw, it's auto-tight.
