  • Corrosion resistance is five times greater than a yellow-galvanised 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 — including in fittings

End mill

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

Ring/counter 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 anchors 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.
