For exceptional applications in utilisation classes 1 and 2. Combines the robustness of a steel screw with excellent rust protection thanks to an extremely corrosion-resistant surface in atmospheres containing salt.
  • Corrosion resistance is five times greater than a yellow zinc-plated surface (500 h in salt spray test as per DIN-EN ISO 9227)

  • Its coating gives the ASSY screw a high-quality stainless-steel appearance

  • Chrome VI-free


Asymmetrical thread


Prevents overturning and makes screwing in easy



AW drive


For perfect bit clamping



Milling pockets


For clean countersinking — in fittings as well



End mill


For less friction on the shaft (with diameters of 5 mm or more and lengths of 70 mm or more)



Ring or mating thread


At the tip, enables screwing close to the edge

Notice

Screws may not be used for


  • Wood containing large amounts of tannic acid

  • Boiler-pressure impregnated wood

  • Direct weathering (utilisation class 3)


ASSY 3.0 chipboard screws are optimised for use in wooden materials. Use in plastic dowels may cause a reduction in the load-bearing capacity. Therefore, we recommend only using screws without optimised thread tips (drill tip, mating thread, ring thread, serrated edge, self-clearing groove etc.) in plastic anchors, e.g. ASSY D, DIN 571 hexagon wood screws or Wüpofast screws.



To attach metals to wood, machine a precise cut-out in the metal tab.
