Product Description
T52 Hollow Anchor System Full Threaded Steel Self Drilling Bar Rock Bolt
Product Overview

System Components
The complete self-drilling anchor bolt system includes:
- Hollow anchor bolt
- Anchor nut
- Anchor plate
- Anchor coupler

Installation Process
The system operates by drilling holes in collapsing soil or loose rock using an efficient hollow bar and drill bit. Following drilling operations, grout is injected through the hollow bar into the surrounding cavity, creating a high-productivity anchoring solution.
