Variants
Cr(6)-free corrosion protection, approx. 500 h, no base metal corrosion (salt-spray mist test in accordance with DIN EN ISO 9227 - NSS)
Countersunk head with milled pockets, for processing in softwood. For use in hardwood, the variant with head Ø 12mm is suitable (type. 0219864..).
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
- The recommended maximum wood thickness lH was calculated with reference to the maximum attachment thickness lU of the surface!
- Wing-pias screws must be appropriately tested for usability for each application case. Only install using application tools with a depth stop and claw coupling
- 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
Drilling screws may only be used where dampness is not to be expected. For fasteners with a construction permit, the permit, and in particular Part 2 "Special regulations", must always be observed.
- Force feeding of the screw is prevented by the wings drilling out the wood
- The core hole is drilled into the substructure. The wings break off upon contact with the metal
- The first few turns of the screw cut the thread, the remainder of the screw then screws into the thread
