- Extremely flexible to use due to three anchoring depths (size 6-14)
- Fastening can be adjusted up to twice after installation (size 6-14), for example in order to align railings or anchor plates (please refer to the assembly guide)
- Very high loads
- Smallest axial and edge clearance due to very low expansion effect
- Very fast and easy assembly and immediately load-bearing
From size 8, we recommend the use of a suitable tangential impact screwdriver for installation. The recommended maximum nominal torque must be observed.
