Abstract

The present disclosure relates to a screw (10) for engagement with wood or similar composite material, such as a decking plane composite material (25), by rotating said screw in a rotational direction (W) around a rotational axis (AC) of said screw. Said screw extending in an axial direction (A) and comprising: a countersunk head portion (12) having a top side (19) for accommodating a driving tool to rotate said screw and an essentially frusto-conical shaped lower portion (18); a shank (14) extending from the head portion to a point tip (11) and having a threaded region (15); wherein said frusto-conical shaped lower portion (18) comprises a cutting recess section (20) having a trailing region (22) as seen in said direction of rotation (W); and wherein said trailing region (22) comprises a cutting edge (23) having a first axial end point (41) and a second axial end point (42) defining an imaginary line (Al), and wherein said imaginary line (Al) defines a positive cutting edge angle (a) relative to a plane (AP), said plane (AP) extending in a radial direction (R), from said rotational axis (AC) to said first axial end point (41), and in said axial direction (A).
