Advantages of tip geometry:
- No pre-drilling
- Chip-free screwing through material displacement
- No need to clean the ventilation ducts of drilling chips
- Higher pull-out values due to the collar bead during thread forming
Zinc-plated steel drilling screws must only be used where dampness is not to be expected.
