Abstract

The spanner is noteworthy in that the spanner body 10 or cylindrical bar defined between the two end sockets 11, 12, or substantially comprising the lever part 10-1, having or not having a shoulder adjacent to the socket in question and the bent head part 10-2 is of constant cross-section S2, and in that this cross-section is set up with respect to the necessary cross-section of the bent head, the lever part of the spanner having a cross-section S2 which is greater than the theoretical cross-section S3 necessary thus forming an excess thickness e along the lever part of the spanner.
