Heavy Duty 9-Shaped Foundation Anchor Bolt

Product details
This 9 shaped anchoring rod is engineered for applications where standard foundation bolts would not provide sufficient holding power. The reverse hook configuration at the end of the rod engages with the concrete in a way that significantly increases pullout resistance, making it suitable for structures subject to high uplift forces. This design is particularly valuable for transmission towers, communication masts, heavy industrial equipment, and bridge components where structural failure would have serious consequences. Available in diameters from M14 to M36 and lengths from 800mm to 3000mm, these rods accommodate the demanding specifications of large-scale infrastructure projects. The materials used — Q345B structural steel or 40Cr alloy steel — provide the mechanical properties required for high-load applications.

The manufacturing process for this anchoring rod involves precision hot forging of the hook end to ensure consistent shape and structural integrity. The steel is carefully heated and formed to create the reverse hook geometry, then heat-treated to achieve the required strength and toughness. Thread rolling follows, creating precise threads that match standard nuts. Hot-dipped galvanizing provides corrosion protection suitable for outdoor use, while black oxide finish may be specified for interior or controlled environment applications. Quality control includes magnetic particle inspection of the hook area to detect any surface or subsurface defects, dimensional verification, and tensile testing to confirm mechanical properties. 9-shaped anchor bolts are frequently specified for tower crane bases, wind turbine foundations, and large industrial equipment anchoring where reliability is paramount.

Installation requires careful positioning of the bolt within the concrete foundation. The hook must be oriented correctly to maximize its anchoring effectiveness, and the bolt must be placed at the correct depth to ensure the hook is fully embedded in the concrete. Proper installation techniques are essential to achieving the full performance potential of the design. For contractors working on infrastructure projects, these bolts provide the confidence that comes with a proven design for critical connections. The reverse hook geometry provides a level of pullout resistance that is not achievable with simpler anchor configurations. L-type anchor bolt serves lighter applications well, but for projects where safety margins must be maximized, 9-shaped anchor bolts offer the performance needed for demanding conditions. Regular inspection during installation helps ensure proper placement and alignment, contributing to the long-term reliability of the structure.
