The Eurotec A4 angle-bracket screw (ABS) has been specially designed for connections between sheet steel and wood. The splitting effect in the wood is reduced by the geometry of the screw tip. In addition, the screw is characterised, among other things, by the smooth shank that sits directly beneath its head which allows for the transfer of shear loads. Thanks to the material (A4 stainless steel) used, this angle-bracket screw is particularly suitable for outdoor applications, as it is rust and acid resistant even in areas located directly on the coast or with high levels of air pollution. Furthermore, the screws can withstand tannin-containing woods.
