Precise positioning of the screw is no problem at all thanks to its centring drilling tip, which was specially designed for this purpose. The drilling cutting edges guarantee perfect drilling performance, just like a Forstner bit. They also prevent troublesome splitting or rupturing of the wood.
Fast screw-in
The gentle start of the thread after the drilling tip enables rapid screw-in.
Easy and clean countersinking
Easy and clean countersinking of the screw is made possible thanks to its milling pockets. Chips formed at the surface during the screwing-in process are collected.
AW drive for optimum guidance and transmission of force
Thanks to the AW drive, a tight fit of the bit in the screw drive is guaranteed. This prevents wobbling impacts and sliding of the bit from the screw while screwing in.

When using these screws, the ETA-11/0190 specifications must be observed.
When selecting the screw length, keep in mind that the thread must be fully anchored into the surface.
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.
Datasheets(X)
Substrates: Solid wood (coniferous wood, ash, beech, oak), laminated beams, cross laminated timber (CLT), timber veneer (coniferous wood or BauBuche), OSB and chipboard.
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.
