Self Drilling Anchor Bolt - T Type

Susun Self Drilling Anchor Bolt system is a fully threaded hollow core bar that is initially a server as a drill rod with a lost bit, and later, once grouted in, it becomes an anchor tendon that can be stressed and locked off with a nut.
Susun Self Drilling Anchor Bolt system provides the optimal solutions for nailing, bolting, micro piling and as ground anchors in difficult ground and rock conditions.
