For precise fastening of decking boards. Many types of wood can be processed without pre-drilling thanks to the drill tip.

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.



Clean and easy countersinking


Countersinking the small countersunk head is clean and easy, thanks to its small diameter. The under-head milling pockets pick up protruding chips. However, with tropical hardwood, countersinking of the surface is recommended, as these types of wood have very short chips.



Extremely robust


The grooved shaft provides for additional screw strength as austenitic stainless steel (A2/A4) cannot be hardened. This virtually eliminates the possibility of the screw tearing off.



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

Screwing down hardwood patio boards


Preliminary tests are required for hardwood. Pre-drilling of the wood may be necessary depending on the density and moisture level of the wood. It is recommended that the processing device be operated at a low speed.



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

Application area

The range of applications of the various stainless steels is contained in the following ISER (German Information Office for Rustproof Stainless Steel, Non-Rusting Steels for Various Environmental Conditions, www.edelstahl-rostfrei.de, Information Sheet 828) table. Rustproof stainless steels (e.g. material no. 1.4016) are recommended there for use in atmospheric processes only for use in a rural environment, and here as well only with great restrictions. We therefore recommend only using austenitic stainless steels for outdoor applications, taking the environmental conditions into account. Stainless steel A4 is especially suitable for use in an industrial atmosphere and for use near the sea.

Stainless steels for various ambient conditions (www.edelstahl-rostfrei.de, Information Sheet 828)

N= lowest corrosion load within the respective environment, indicated e.g. by low temperatures and low humidity
M= medium corrosion load within the respective environment
H= highest corrosion load within the respective environment, e.g. due to continuous high humidity, high ambient temperatures, particularly aggressive air pollution
x= meets the requirements in principle, however, cheaper steels may also be sufficient
+= probably best material choice in terms of corrosion resistance and costs
(+)= adequate performance as long as certain precautionary steps are taken. Smooth surfaces and regular cleaning are required in particular
-= heavy corrosion expected
