The self-drilling screw with up to 50% time savings when fastening wood to metal sub-structures
  • Bimetal (A2 stainless steel/drilling tip made of case hardened steel)

  • RUSPERT® coated (silver)

  • With self-tapping thread

  • Countersunk milling head for use with 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
  • Wing-piasta 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


∅ 3.9/4.2/4.8 mm)


For use with wood and gypsum material boards and cement-bound mineral construction material boards with thin-walled steel profiles.

Instructions

How it works


  • 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
