Drilling, threading, screwing-in — all in one work 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
- The pressed-on flange generates a lower surface pressure, which helps to prevent stress cracks
- Contact pressure during use approx. 100 N/screw in with depth stop if necessary
- Drilling screws must be processed with a suitable drill driver (e.g. cordless drill driver with depth stop)
- The use of impact screwdrivers is not permitted
- Drilling screws must be attached perpendicular to the surface of the component
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.
