ESSVE HDS Decking screw A4 is intended for concealed installation of common pressure-treated decking timber, Siberian larch, etc. The screw is installed in the side of the decking board with the help of a specially adapted bit and an installation tool.

The screw is made of stainless acid proof steel A4. The arrow shaped point minimises the risk of splintering and reduces the drive-in torque. There is also a thread below the head that creates a high clamping force between the decking board and the supporting joist, the cylindrical head gives a barely visible entry hole. The screw is fitted with TX-bit drive and conforms to the CE requirement set out in EN14592.
