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.

These screws find extensive use in industries ranging from woodworking and metal fabrication to automotive and construction. They are particularly useful when working with thinner materials like sheet metal, plastics, or fiberboard, where traditional threading may not be feasible. In automotive applications, they are used for body panel assembly, while in construction, they might be employed for attaching drywall or roofing In automotive applications, they are used for body panel assembly, while in construction, they might be employed for attaching drywall or roofing In automotive applications, they are used for body panel assembly, while in construction, they might be employed for attaching drywall or roofing In automotive applications, they are used for body panel assembly, while in construction, they might be employed for attaching drywall or roofingwafer head self tapping screws.
