Stainless steel A4. The screw for fastening patio boards. Many types of wood can be processed without pre-drilling thanks to the drilling 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

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.


The range of applications of the various stainless steels is detailed in the following table issued by the ISER (German Information Office for Rustproof Stainless Steel, Non-Rusting Steels for Various Environmental Conditions, www.edelstahl-rostfrei.de, Information Sheet 828). 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.



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