Never drill deeper than 80% of panel thickness, always clean the drilled hole and
always use the correct length load controlled expansion anchor.
This will prevent blow out in panels and eliminate costly repairs.

The new Proprietary PBI Structural Anchor is a heavy-duty thick
sleeve expansion anchor. It is vibration resistant and removable.
The anchor is available in a flange hex head version and can be
used in concrete, stone and some types of solid brick and core filled
blockwork. The anchor diameter of the PBI structural anchor is the
same as the drilled hole, which eliminates layout or hole spotting.
The PBI Structural Anchor is a torque (load) controlled thick sleeve expansion anchor, which is suitable for all
applications requiring high performance with minimal slip. Its unique design ensures efficient load carrying
capacity in both tension and shear.
Powers Fasteners have tested the PBI Structural Anchor in accordance with AS 3850 鈥?2003 (Tilt-up concrete
construction standard) for bracing of tilt-up concrete panels.
AS 3850 鈥? 2003 states that where expansion anchors are to be used as brace fixing or structural connection
fixing inserts they shall be of the load-controlled type and the WLL (Working Load Limit) shall be limited to 0.65 of
the first slip load.
Hardened Tapered cone with
optimum geometric design for Typical Applications:
maximum anchor expansion 鈥? Bracing of Tilt-up concrete panels
鈥? Structural connections including column bases, beam supports etc.
鈥? Scaffolding tie back to concrete and masonry
鈥? Heavy machinery
3. Anchor Design Criteria 4. Combined Loading
The minimum recommended thickness of base material, BMT, when using the PBI
Structural Anchor is 125% of the embedment to be used. For example, when installing Anchors loaded in both Tension & Shear shall be designed to satisfy -
an anchor to a depth of 100mm, the base material thickness should be 125mm.
