- Drilling, thread forming and screwing in one step, saving significant time and effort
- Ensures an exact drill hole diameter for each screw connection and therefore minimises thread tolerance, so that an optimal connection is always created
- Prevents mistakes in the installation
- Self-drilling screws must be installed with a suitable drill/driver (e.g. cordless drill/driver with depth stop)
- The use of impact drivers is not permitted
- Self-drilling screws must be screwed in perpendicular to the surface of the component
Zinc plated self-drilling screws must only be used in locations where permanently damp conditions are not expected - condensation is not considered a permanently damp condition (corrosivity category ≤ C2 in accordance with DIN EN ISO 12944-2). For fasteners with technical approval, the approval, and in particular Part 2 "Special regulations", must always be observed.
