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.

One of the most significant advantages of chemical anchor fasteners is their high load-bearing capacity. Unlike traditional mechanical anchors, which can be limited by the tensile and shear strength of the materials they penetrate, chemical anchors distribute loads more evenly across a larger surface area. This is particularly beneficial in applications where heavy loads are expected, such as in building facades, heavy machinery installations, or structural reinforcements.
