T40 Anchor Bolt

• Brief Introduction
T40 anchor bolt is one of the T-thread self-drilling hollow injection anchor bolt. It is widely used in the railway system, metro project, etc. It can be installed in sites with weak rocks, loose soil, weathered layer, sand with stone layer and so difficult to create a hole in complex formation. The unconsolidated ground condition favor the self drilling anchor bolt technique for fast and simple method of installed compared to the traditional method.
