The primary structure of a wedge-type anchor consists of a threaded rod, a nut, a washer, and the wedge itself. The threaded rod, often made from durable materials like steel or stainless steel, is inserted into a pre-drilled hole. As the nut is tightened, the wedge is forced against the inner wall of the hole, causing the anchor to expand. This expansion generates a powerful frictional force that locks the anchor in place, providing exceptional holding power.

One of the primary benefits of using 2-inch self-drilling screws is the time savings they offer. In projects where speed is essential, these screws can significantly reduce the overall construction time. Without the need to pre-drill holes, workers can quickly set up and fasten materials together, increasing productivity. This is particularly advantageous in situations where time constraints are a critical factor, such as in commercial construction or during emergency repairs.
