These Hikoki 3.3x70/58 duplex nails are specifically designed for use with the NR3675DD nailer, making them a practical choice for assembly work where connecting frame elements requires a temporary or adjustable hold. Made from resistant steel with a galvanized coating, they are protected against corrosion, which helps maintain the integrity of your project over time. Each pack contains 2000 pieces, and their collation is engineered to allow you to reach narrow or difficult spots that would otherwise be hard to access. This makes them particularly useful for professionals working on structural frames who need a reliable fastener that can be removed more easily than standard nails.
