My brother used this and was happy with results. He added wood glue using syringe like posted above then used these snap screws to draw it together.
One tip he gave me was to soap/wax the screw first. It goes in easier and doesn't cause premature snapping off of the screw head.

I have hardwood throughout house with the same issue in hallway. But I also like knowing if someone is coming so the squeak will stay for now.
I got a dog that will bark if a deer is in the yard, when the dog is in the house. Don't need no squeaky floor.
Appreciate the info on soap/wax....good idea.
