Boards that will not hold a screw? OK, I'll bite. What kind of wood? What fastener? What direction into the wood? How was the wood stored prior to use?

Forgive my skepticism, but for wood boards (and not engineered materials being used incorrectly), ones not stored in deeply failure-causing conditions to the point where you wouldn't want to touch them because they'd be gross, this just does not happen.

Then it gets thrown away by your framers. Otherwise the nailing pattern (generally every 12" or 6" at sheathing edges) is over-engineered to cover cases where you have sub-optimal pieces of wood (twisted, warped, holes, etc).

And I've come across screws that won't hold a board securely. The screws just cracked.. It was only a table and a gate. From now on I test the screws i use for how much it takes to brake in half, and if it bends or just snaps

You werent using OSB on walls were you? Which goes back to the moisture thing...
