ANCHORING SYSTEMS 8

Undercut anchor HDA-T

BASE MATERIALS Approvals
● Concrete (cracked) BZS D 09-601 for HDA self-cutting undercut
BZS/shock
● Concrete (uncracked) anchor
ETA 99/0009 for HDA self-cutting undercut
ETA
anchor (ETAG 001-03, Option 1)
APPLICATIONS Approvals and test reports may apply to selected products only. Please refer
● Safety-relevant, heavy-duty fastenings for all dynamic loading to the documents for details.
(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
● Self-undercutting facilitates fast and reliable installation
without the need for a separate undercutting tool or additional
operations
● Combines the advantages of a post-installed mechanical
anchor, i.e. flexibility and immediate loading, with the
performance of a cast-in-place headed stud
● Close spacing and small edge distance thanks to low expansion
forces These are abbreviated instructions which may vary according to the application.
