Expert Verdict Reviewed by the SuperArbor Pro Desk

Metal cap nails are the standard choice for securing underlayment and synthetic wraps where plastic caps are not specified; space and pattern them per the underlayment manufacturer and local code. On large decks, a 50 lb. bulk box minimizes restocking. Switch to longer fasteners when penetrating into thicker sheathing or over furring.

Wear eye protection and gloves when hand-driving nails and when handling metal caps and sharp shanks.
