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)

Application recommendation

Base material thickness

X-CR M8-__-42 P8:

hmin = 100 mm
