Self drilling anchor bolts have many advantages, such as simple installation, simple operation and better anchorage effect. The specific performance is as follows: Self-drilling bolts increase productivity by eliminating the installation and removal of casing. There is no extensive soil survey and all different soils have the same installation principles. Continuous threads allow the link to cut or extend on any length of rod. Compared to solid bars, it is lighter and easier to install. The free length can simply be extracted in a temporary anchor. The rod produces a higher shear resistance in the soil than a solid rod of the same cross-section. During drilling and grouting, drill rod anchors act like concrete shakers and therefore produce a uniform and compacted grout.

Although the SDA bolt is a new type of anchoring support tool, it has applications in many projects due to its numerous advantages. It is used in many projects such as tunnel advance support, slope protection, micro piles, water conservancy and hydroelectric projects, coal mine roadway support and so on. Self drilling bolt also has the advantage of adaptability, anchoring can be achieved under any geological conditions.
