Strong structural screws
I've bought several packs of these to build a deck and use while building my house. They are strong and appear to be made very uniformly.

Joint didn’t hold w
Not a structural screw. Ok for decking holds well. But to tie in posts or joints I’m using structural screws like Headlok.
