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.

In terms of specifications, the 8mm hex head bolt adheres to international standards such as ISO, DIN, and ASME. These standards ensure consistency in dimensions, tolerances, and performance characteristics, facilitating compatibility across different industries and countries. The bolt's length, apart from the diameter, is another critical factor. It should be chosen based on the thickness of the materials being joined and the required clamping force.
