T64 SDA Bolt
T64 SDA Bolt offers significantly enhanced tensile and compressive capacity, with high rigidity and strong load-bearing performance, making it suitable for deep-hole anchoring and deep reinforcement of surrounding rock.
T64 SDA Bolt Overview
The T64 SDA bolt is designed for high-load ground reinforcement and demanding geotechnical applications. Featuring a 64 mm outer diameter, the T64 provides an ultimate load capacity of up to 1,160 kN and a yield load capacity of up to 930 kN. Its large-diameter hollow structure supports drilling and grouting through the anchor bar, while the T-thread provides reliable connection and load transfer.
