Specification points

Product description

For precise fastening of terrace boards. The drill bit allows you to work with many types of wood without pre-drilling. The screws for the terraces are made of stainless steel A2 and are color-matched to the appearance of the wood. They are ideal for outdoor terraces and facade construction.

Precise positioning and no cracking

Accurate positioning of the screw is no problem thanks to the centering drill bit, which has been specially designed for this purpose. Drilling cutting edges guarantee a perfect drilling result the same as with a Forstner drill. They also prevent unpleasant splitting or cracking of wood.

Easy and clean countersinking

Accurate positioning of the screw is no problem thanks to the centering drill bit, which has been specially designed for this purpose. The milling pockets under the head remove protruding chips. However, for tropical wood, it is recommended to embed the surface, as wood of this type has very short chips.

Extremely strong

The knurled shank provides increased screw strength because austenitic stainless steel (A2 / A4) cannot be hardened. This essentially eliminates the likelihood of the screw tearing off.

AW groove for optimal guidance and power transmission

The AW slot ensures precise positioning of the bit in the screw slot. As a result, the screw does not throw or the bit slips off the screw during screwdriving.

Notice

For screwing hardwood patio boards. For hardwood, a preliminary test must be performed. Pre-drilling of wood may be necessary depending on the density and humidity of the wood. It is recommended that the work tool operate at low speed. The specifications of ETA-11/0190 must be observed when using these screws.
