Abstract
A hole-shaping and thread-forming screw (1) has a non-cutting hole-shaping end section (2) that ends in a point, a shaft section (4) provided with a thread and an engagement section (5) with a tool. The tapering end section (2) of the screw (1) has a flattened part (12) at least approximately parallel to the axis of the screw that extends over less than 180 DEG and reduces the cross-section of the end section (2) over part of its length. This non-cutting hole-shaping screw may thus be driven much more easily into a workpiece.
