2. Material Composition Typically made from high-strength steel, roof self-drilling screws are often coated with corrosion-resistant materials such as zinc or polymer to enhance durability. This resistance to rust and degradation is vital, especially in harsh weather conditions, ensuring the longevity of the roofing system.

4. Ease of Installation The combination of their head design and drive type allows for quick and efficient installation, saving time and effort during assembly.

Hex head self-drilling screws, often referred to as Tek screws, are designed with a hexagonal head that allows for easy tightening using a wrench or a socket. The self-drilling feature means that these screws come with a drill bit tip that can penetrate metal, wood, and other materials without the need for pre-drilled holes. This eliminates the need for additional tools, making installation faster and more efficient.

3. Reduced Risk of Leaks Properly installed self-drilling screws significantly decrease the chances of leaks that can result from improperly fastened or pre-drilled holes. By eliminating the need for pre-drilling, these screws ensure consistent and precise placement, providing peace of mind for building owners.

1. Time Efficiency One of the main benefits is their ability to drill and fasten in one motion. This results in quicker installation times and potentially lower labor costs.
