Expert Verdict — Reviewed by the SuperArbor Pro Desk
Use 18 in. fasteners only where the specified assembly truly requires that length, such as thick or tapered insulation over deep decks; oversized fasteners add cost and can be harder to keep plumb. Drive square to the deck with an adjustable clutch screwgun. Pair with the JM plate specified in the wind-uplift assembly.
Long fasteners are heavy and sharp-pointed; handle cartons with proper lifting technique and wear gloves and eye protection during installation.
