Abstract (en)
[origin: WO2018074972A1] A screw (10), extending in an axial direction (A), for engagement with wood or similar composite material, by rotating said screw in a rotational direction (W) around a rotational axis (AC), comprising: a shank (14) having a threaded region (15); a countersunk head portion (12) having a top side (19) with a driving-tool receiving recess (43), and an essentially frusto-conical lower portion (18), comprising a cutting recess section (20) having a trailing region (22), as seen in the rotational direction (W), comprising a cutting edge (23) with a first axial end point (41 ) and a second axial end point (42), defining an imaginary straight line (Al), which defines a positive cutting edge angle (a) relative to a 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); wherein the extension of the maximum depth of a cutting recess section (20) in the radial direction (R) is essentially aligned with the innermost point (46) of the driving-tool receiving recess (43).
