Precise positioning and no splitting
Rapid spot drilling of the screw is no problem at all thanks to its special drill tip. Also prevents irritating splitting or rupturing of the wood.
Clean and easy countersinking
Countersinking the small countersunk head is clean and easy, thanks to small diameter. 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 transmission
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.
Screwing of hardwood decking boards
Preliminary tests are required for hardwoods. 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.

Datasheets(X)
The range of applications of the various stainless steels is detailed 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 in terms of atmospheric conditions only for use in a rural environment, and in this respect only subject to significant 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.
