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.

- Strong Connection The ability to form threads in the base material ensures a strong and secure connection, capable of withstanding various forces and loads.

3. Thermal Expansion Materials expand due to heat. When temperature variations occur, the differing rates of expansion between the anchor bolts and the material they are affixed to can create stress, leading to loosening. This is especially common in environments with extreme temperature fluctuations.

Overall, self-drilling anchor screws are a convenient and reliable fastening solution for a wide range of construction projects. From simple DIY tasks to large-scale commercial installations, these screws offer a time-saving and cost-effective alternative to traditional drilling and anchoring methods. With their versatility, durability, and ease of installation, self-drilling anchor screws are a valuable addition to any toolbox.
