Self-drilling anchors are designed with a screw point and cutting edges that allow them to cut through various substrates, including rock, concrete, and steel. They also have a thread section that allows for immediate load transfer after installation, providing immediate stability to the structure. This feature is invaluable in situations where immediate support is required, such as in slope stabilization, foundation repair, or even in temporary works during construction.

The bolts are then inserted, often with a nut and washer attached at the end to maintain position. A chemical grout or concrete is then poured around the bolt to fill the void, creating a strong mechanical connection.
