Steel, Ruspert®-coated (grey), AW drive. The self-drilling screw with up to 50% time saving when fastening wood to metal sub-structures

Corrosion protection

Approx. 500 hrs. no base metal corrosion in accordance with DIN EN ISO 9227 — NSS

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

Wing-pias must be appropriately tested for usability for each application case. Only install using application tools with depth stop and claw coupling.

The maximum attachment length is calculated as follows: Wood thickness and substructure thickness lU = max. attachment thickness lB

Application area

For use with hard and soft woods

  • 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
