The self-drilling screw with up to 50% time savings when fastening wood to metal sub-structures.

Steel, yellow galvanized

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
Proof of Performance

For 3.9/4.2/4.8 mm diameters

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 fasteners with a construction permit, the permit, and in particular Part 2 "Special regulations", must always be observed.

Instructions
  • 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
