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
Notice
  • 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.
