5" Nails – The Heavy Hitter – Built for Pole Barns & Massive Timber

Building a pole barn? Stacking landscape ties for a retaining wall? Framing a heavy timber pergola? Regular nails won't even reach halfway. At 5 inches long, these monsters punch through a 4x4 (3.5 inches) with 1.5 inches to spare – deep enough to lock into the support behind it. The extra-thick shank won't bend or shear under heavy loads. Hot-dipped galvanized means they laugh at moisture, ground contact, and pressure-treated chemicals. When the job is massive, nail massive.
