The self-drilling anchor nut secures the entire self-drilling anchor system, ensuring it remains fixed at the designated anchoring point. It is available in both hexagonal and spherical types, and it reliably transfers load from the anchor plate to the anchor bar. To account for angular deviations, at least one end of the nut is designed with a spherical cap.
All anchor nuts are engineered to safely transfer the specified system load, guaranteeing reliability and stability.

The self-drilling anchor system is an advanced anchoring solution on the market. It provides stability in soil or rock formations and is a key anchoring system in rock reinforcement projects, ensuring safety and structural rigidity.
Our self-drilling anchor is equipped with different parts. At the drilling end is the anchor bit, which creates the borehole while facilitating grouting. The anchor bolt, serves as the primary support structure. The anchor coupler extends the bolt's length when necessary, while the anchor plate distributes surface loads to ensure stability. Finally, the anchor nut locks the system securely in place, completing the setup for optimal performance.
