The Tolsen 54025 concrete nails are designed for secure fastening in high-hardness cement walls, hard soil, and concrete surfaces. Each nail features a diameter of 3.8 mm and a length of 76 mm, providing a sturdy grip for various construction tasks. To ensure stability, the shafts are engineered with vertical ribs that increase friction and prevent the nail from slipping once driven. The zinc-plated galvanized finish protects the metal from corrosion, making them reliable for long-term use. These nails come in a 1 kg colored box, offering a practical quantity for those working on masonry or heavy-duty anchoring projects.
