HDA undercut anchor system
Base materials
■ Concrete (cracked)
■ Concrete (uncracked)

Applications
■ Safety-relevant, heavy-duty fastenings for all dynamic loading shock, seismic and fatigue) in cracked or uncracked concrete, including applications in nuclear power plants
■ Fastenings to support heavy pipes, safety barriers, industrial machines, crane rails, dorm structures, crash barriers, roof fixings, elevator tracks, bridge retrofitting etc.

Advantages
■ Combines the flexibility and immediate loading capability of a post-installed mechanical anchor with the performance of a cast-in-place headed stud
■ Close spacing and small edge distance thanks to low expansion forces
■ Self-undercutting facilitates fast and reliable installation without need for a separate undercutting tool or additional operations
■ The resulting keying effect provides a secure hold even in cracked concrete under dynamic loading
■ Manufactured under an NQA-1 nuclear quality assurance program with comprehensive approvals
■ Completely removable, if necessary
