- The new thread geometry ensures smooth screwing into the concrete and thus greater efficiency
- The fastest type of fastening for medium loads
- Three effective anchorage depths allow flexible application
- Attachments can be adjusted up to twice retrospectively, for example to be able to align anchor plates (observe installation instructions)
- Minimum spacing and edge distances due to very low expansion effect
European technical assessment ETA-22/0123 for fixing point option 1, cracked and non-cracked concrete:
- Static and quasi-static effects (∅6)
- Seismic effect, performance category C1 (∅6)
- Fire resistance R30, R60, R90, R120
When installing with a tangential impact screwdriver, the recommended maximum rated torque must be observed. When used outdoors, the drill hole can be sealed with WIT-BS injectable mortar.
