Products Description
A T-thread self-drilling anchor features a sturdy trapezoidal thread form that delivers distinct mechanical advantages. Compared with standard R-thread anchors, its unique profile provides a greater contact area between the steel bar and grout, enhancing bonding performance and frictional resistance. This results in higher anchoring stability and significantly improved load-bearing capacity in practical engineering applications.
