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
- 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
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.
Datasheets(X)
- 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
