Screws are ok for framing which is not structural. Like partition walls in basements mostly. Holmes is using a structural screw in his shows. Only because most folks can not use nails the old fashioned way...with a hammer.
You gotta remember...these folks are newly trained actor builders.
His method is good but also more expensive.
His framing issues should be addressed, this will lead to others to think screws are ok for framing. In reality a regular screw, not structural screw is hardened when it is made, and will snap if any load is put on it. If you put a 3 inch sheetrock screw into a stud halfway, and hit it sideways with a hammer it will snap off.
If you do the same with a nail, it will only bend. This is called shear strength. I have seen decks collapse because folks used screws in hangers with no nails into the wood.
My advise...buy nails and when you use the old fashioned hammer....don't hit the wrong nail.
