The Tolsen 54024 concrete nails are designed for secure fastening in demanding materials like hard cement walls, concrete surfaces, and hard soil. Each nail measures 3.8 x 65 mm and features a zinc-plated surface that helps protect the metal from corrosion over time. To ensure a stable hold, the shaft is engineered with vertical ribs that increase friction, which prevents the nail from slipping out once driven. These come in a 1 kg colored box, providing a practical quantity for those tackling masonry projects or heavy-duty installations.
