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.
Test report on air tightness from the European Test Centre for Domestic Ventilation Equipment, Dortmund (Europäisches Testzentrum für Wohnungslüftungsgeräte e.V. - TZWL), test no.: M.78.06.375
- Screw connections of ventilation ducts and pipes
- Max. sheet thickness to be drilled through: 2x 1.25 mm
- Fixing of e.g. WÜRTH VARIFIX® ventilation duct brackets and suspended items on ventilation ducts
