- DX-Kwik method (pre-drilling) for fastening to concrete: fcc ≥ 20 N/mm2.
- A sufficient redundancy has to be ensured, that the failure of a single fastening will not lead to collapse of the entire system.
- Observance of all pre-drilling requirements.
- For more details in relation to base material properties, please refer to the chapter Fastener selection guide in the Direct Fastening Manual (DFTM)
