Self-drilling screws, also known as “Tek” screws, feature a unique design that incorporates a drill bit-like tip, allowing them to create their own hole as they are driven into materials. This feature eliminates the need for pre-drilling, saving time and effort during installation. Galvanized screws, on the other hand, are coated with a layer of zinc to enhance their corrosion resistance. This dual functionality makes self-drilling galvanized screws ideal for a wide range of applications, especially in outdoor and critical structural projects.
