Expert Verdict — Reviewed by the SuperArbor Pro Desk
Cap nails are the standard choice for holding underlayment against wind uplift because the cap distributes load across the sheet. Use the 1-3/4 in. length when fastening through thicker underlayment or into decks where longer penetration is needed. Follow underlayment manufacturer spacing requirements for cap placement.
Wear gloves and eye protection when handling and driving cap nails; metal caps and cut wire ends are sharp.
