Sounds like I caught the error or at least omission on the manuals part.
When it said to tread them and and then omitted removing them but had you applying glue I knew that sounded wrong.
I thought to myself but if I don't remove the screws they will not come out again~~or am I wrong and the CA won't bind to the metal screws? Can't be!
I just thought I would ask here first and make sure I was not missing anything.
It's hard for the people writing these manuals when they have to assume that you might be a rookie and might not know just how things are done or the intent of what they are saying to do.
But then again that's why forums like this exist!

Again, thanks for the help folks!
