The self-drilling screw with up to 50% time savings when fastening wood to metal sub-structures
Zinc-plated steel
With self-tapping thread
Countersunk milling head for use with hard and soft woods
AW drive system
- Enhanced torque transmission
- Longer life
- Optimum centring
- Better mounting output thanks to fatigue-free screwing in; the required contact pressure for transmission of the torques is considerably lower
- Largest possible contact surface of bit in screw drive
- Even force distribution prevents damage to the surface-protection coating and therefore ensures better resistance to corrosion
Notice
The recommendation for the maximum wood thickness lH was calculated with reference to the maximum attachment thickness lU of the substructure.
Wing-pias® must be appropriately tested for usability for each application case. Only install using equipment with depth stop and claw coupling.
For 3.9/4.2/4.8 mm ∅
General construction permit Z-14.4-634
For use with wood and gypsum material boards and cement-bound mineral construction material boards with thin-walled steel profiles.
Drilling screws may only be used where dampness is not to be expected. For connection elements with a construction permit, the permit, and in particular Part 2 "Special regulations", must always be observed.
