Abstract (en)

[origin: FR2703619A1] Each side of the active head, of roughly polygonal cross-section, of the tool consists of two half-sides of which the active regions (5, 8) are asymmetric with one another relative to the mid-plane (7) of this side, so as to apply to the driven profile a torque which is greater in one direction relative to the other for a given stress to which the tool is subjected. Application to various types of keys or spanners. <IMAGE>
