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


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.

Application area

Suitable for use outdoors in accordance with utilisation class 2 (NKL 2) DIN 1052:2008 (covered, open structures)


Screw-in angle 0° to 90°. For coniferous wood or wood-based materials made from softwood, the screw connection is made without pre-drilling. To reduce the edge distances, a pre-drilled hole can be made according to the core diameter. When screwing into hardwood, pre-drill according to ETA-11/0190.
