Timco Heavy Section Countersunk Self Drill Screws are specially designed for heavy-duty applications where a high level of durability and strength is required. These screws have a countersunk head that sits flush with the surface of the material being fastened, providing a neat and finished appearance. The self-drilling feature of these screws eliminates the need for pre-drilling, making installation fast and easy. This feature also helps reduce the risk of splitting and cracking of the material being fastened. These screws are commonly used in construction applications, such as steel framing, metal roofing, and cladding.
