The Tolsen 54127 is a self-drilling screw designed for securing metal sheets, profiles, and aluminum components. These fasteners feature a 4.8 mm diameter and a length of 38 mm, allowing you to join materials quickly since no pre-drilling is required. Each screw is finished with a zinc galvanized coating to help protect the metal from corrosion over time. Equipped with a Phillips head for a reliable grip, these screws come in a colored box containing 250 pieces. This quantity makes them a practical choice for those working on larger metal assembly projects where consistent fastening is essential.
