Permanent screw connection, clean look
The under-head thread secures the decking board cleanly to the supporting construction. The narrow cylinder head creates a clean look on the decking surface. Pre-drilling serves to further enhance this effect.
Precise positioning, no rupturing
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; the wood does not split, even when screwing near the edge.
Easy and clean countersinking
The small cylinder head can be countersunk very easily and cleanly thanks to its small diameter. For visual reasons, countersinking is therefore advisable.
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.
Screwing of hardwood decking boards
Preliminary tests are required for hardwoods. Pre-drilling of the wood may be necessary, depending on the thickness and moisture level. It is recommended that the application tool is operated at a low speed.
The range of applications of the various stainless steels can be found in the following table from the ISER (Informationsstelle Edelstahl Rostfrei [German Information Office for Rustproof Stainless Steel], information leaflet 828).
In terms of atmospheric conditions, this only recommends rustproof stainless steels (e.g. material no. 1.4016) for use in a rural environment, and here only subject to significant restrictions.
We therefore recommend using only austenitic stainless steels for outdoor applications, taking the environmental conditions into account.
