All Sinodrills SDA products strictly conform to international ISO thread standards, such as ISO 10208 and ISO 1720. Small tolerances ensure system components (Anchor Bars, Couplers, Nuts, Plates) work seamlessly together, guaranteeing qualified system load performance.
Dimensional Tolerances
Using selected raw materials and fully automated production lines, Sinodrills ensures consistent quality across all products, meeting the high expectations of our customers.
Pass Rate
Ductility, measured by the Agt value, indicates a material’s ability to deform before breaking. Sinodrills ensures all SDA bars achieve a minimum Agt value of 6%, exceeding the safety requirement of 5%. This enhanced ductility provides greater safety and durability in challenging environments.

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.
