- Extremely flexible to use due to three anchoring depths
- Fastening can be adjusted up to twice after installation, for example in order to align anchor plates or rails (please refer to the assembly guide)
- High loads
- Smallest axial and edge clearance due to very low expansion effect
- Very fast and easy assembly and immediately load-bearing
When installing with a tangential impact screwdriver, the recommended maximum rated torque must be observed.
