Tek screws, also known as self-drilling screws, are engineered fasteners designed for metal-to-metal or metal-to-wood applications. The distinguishing feature of tek screws is their sharp, drill-like point, allowing them to create their own hole as they are driven into a material. This capability eliminates the need for pre-drilling, which can save significant time and effort during installation.

There are various types of expandable anchors, including wedge anchors, sleeve anchors, and drop-in anchors. Each type serves specific purposes and offers distinct advantages depending on the application and substrate being used. For instance, wedge anchors are ideal for heavy-duty applications, while sleeve anchors are more versatile, accommodating both solid and hollow materials.

Beyond exterior applications, these screws are also utilized in structural components, HVAC installations, and even in prefabricated metal buildings, where quick assembly is a critical aspect of the construction process. The robustness of Tek screws signifies that they can withstand the harsh conditions typically present in building sites, which further enhances their appeal.
