Expert Verdict Reviewed by the SuperArbor Pro Desk

HDG coil nails are the value choice for cement board, fence pickets and exterior trim where conditions are moderate; specify stainless near saltwater or where staining matters. Match length so the nail penetrates framing or sheathing at least 1 in., and step up to the 3 in. x .120 when fastening through furring. Store coils dry to protect the coating.

Always wear eye protection and follow your nailer’s operating manual; keep the muzzle flush to prevent ricochets.
