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.

- Bridges A325 bolts play a critical role in ensuring the stability and safety of bridge structures, particularly in high-stress areas where loads vary dynamically.

Furthermore, it is essential to consider the material being anchored into. Different substrates—such as concrete, brick, or hollow blocks—have varying characteristics that can influence the performance of expandable anchors. Therefore, understanding the existing conditions and selecting the appropriate anchor type is vital.
