Abstract

See full text

A screw, especially for wood, has a knurled region (10) with two sets (11A, 11B) of ribs (11) that are offset from each other by an azimuth angle. For example, the two sets of ribs extend towards each other from opposite ends (10A, 10B) of the knurled region (10) and are intertwined only in an overlap region (12) that is at the middle of the knurled region.
