- 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
Prevents overturning and makes screwing in easy
For perfect bit clamping
For clean countersinking — in fittings as well
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.

When using these screws, the ETA-11/0190 specifications must be observed.
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.
