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
Notice

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

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.
