Precise positioning and no splitting

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 irritating splitting or rupturing of the wood.

Fast screwing

The gentle start of the thread after the drill tip enables rapid screwing in.

Clean and simple countersinking

The milling pockets facilitate clean and simple countersinking of the screw. Chips formed at the surface during the screwing-in process are collected.

AW drive for optimum locating and power transfer

The AW drive guarantees an excellent fit of the bit in the screw drive. This prevents wobbling impacts and sliding of the bit from the screw while screwing in.

Notice

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.

ETA-11/0190

Application area

Fastening of wood-wood or steel-wood connections in furniture construction, shopfitting and timber construction applications and for internal fittings.

Substrates: Solid wood (coniferous wood, ash, beech, oak), laminated beams, cross laminated timber (CLT), timber veneer (coniferous wood or BauBuche), OSB and chipboard.

Instructions

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.
