Retaining wall holding back tons of soil? Railroad ties stacked six feet high? Timber bridge over a creek? You don't need a nail. You need a 6-inch spike. These aren't your grandfather's finishing nails – these are heavy-duty, industrial-grade fasteners that weigh almost an ounce each. At 6 inches long, they'll punch through two stacked 4x4 landscape timbers (7 inches total) and still have room to spare. The thick shank won't bend under a sledgehammer. The hot-dipped galvanized coating survives decades in wet ground. When the job is measured in tons, fasten by the inch – 6 of them.
