Galvanized steel, blue passivated (A3K)
Drilling, threading, screwing-in — all in one step
Therefore considerably reduced time and effort
Exact drilling diameter for each screw connection
- Resulting in minimisation of thread tolerance
- Always an optimum connection
Prevents installation errors
NoticeContact pressure during use approx. 100 N/screw in with depth stop if necessary
Galvanized drilling screws may only be used where dampness is not to be expected. For fasteners with a construction permit, the permit, and in particular Part 2 "Special regulations", must always be observed.
