Screw, its use and a method for fastening workpieces and decking a terrace

A screw (1) for drilling and screwing through a workpiece (18) of a plastic or wood plastic composite, wherein the screw (1) has a central longitudinal axis (8) and comprises a stem (4) with a screw head (2) at a first end and a drill point (3) at an opposite second end and a first thread (5) around the stem (4), wherein the first thread (5) is adjacent to the drill point (3) and configured for screwing into and through the workpiece (18) after pre-drilling with the drill point (3), wherein the drill point (3) comprises a foremost tip (7) for initial workpiece (18) contact during start of drilling and screwing into the workpiece (18),

• wherein the tip (7) is eccentrically displaced from the central axis (8),
• wherein the drill point (3) comprises
• a cutting edge (10) extending from the tip (7) to the stem (4) and a cutting face (11) extending from the cutting edge (10) inwards towards an inner part of the drill point (3) and forming a first side of a slot (14) in the drill point (3), the cutting face (11) being configured for working the workpiece (18) during drilling and screwing of the screw (1) in the workpiece (18),
• a convex curved outer surface (9) tapering along the drill point (3) from the stem (4) to the tip (7) and extending over an angle of no less than 225 degrees and no more than 330 degrees about the central axis (8) as measured from the cutting edge (10),
• a second face (13) extending from the curved outer surface (9) inwards and to the cutting face (11) and forming a second side of the slot (14);
• wherein the cutting face (11) is planar and parallel to the central axis and extends laterally from the cutting edge (10) radially inwards towards the central axis (8) and to the central axis so as to follow a plane that contains the central axis (8).
