Drilling, threading, screwing-in — all in one work step
Therefore considerably reduced time and effort
Exact drilling diameter for each screw connection
This minimises the thread tolerance thereby always ensuring an optimum connection
Prevents installation errors
- 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 approval, the approval, and in particular Part 2 "Special regulations", must always be observed.
