An admittedly trivial question, but how to use 7th screw on 6 hole hinge?

Admittedly it's a trivial question. But it irks me that the manufacturer / retailer don't tell you the answer.

Bought some hinges for interior doors in the house. They each came with 7 screws. 6 shorter and all the same length. the 7th is longer.

What to do with the 7th? I figure you can use that if you are hanging a heavy door to help keep the hinge from pulling out? You'd put the longer one in the top hole in the door frame?

But the instructions don't mention the 7th. calling their customer disservice number, it answers 'thanks for calling lowes' so it's their private brand? And they will call me back in 26 to 49 minutes 'cause the que is long. I bet the person will have no clue.

Going to the lowes website and searching on the 3 different numbers on the bag get nothing found.

1) Am I right about how to use the long screw?

2) How do you move past stupid things like this - you buy something and questions can't get answered? I have OCD and waste time trying to get answers.

 

The long one goes in one of the holes closest to the door stop.
