Claim:
A wrench comprising: a head having a first and a second opposite wide sides, the two wide sides being displaced axially from each other; and an actuating arm being integrally connected to the head, both of the wide sides forming an opening having two cheeks running parallel and opposed to each other for torque transmitting engagement on two parallel opposed faces of a polygonal profile of a nut or a bolt head; the two opposed cheeks forming two jaw cheeks on the first wide side and two jaw portions on the second wide side; characterized in that the jaw portions of the second wide side are symmetrical and in alignment with the jaw cheeks of the first wide side; wherein between the jaw portions of each of the two opposed cheeks an angular recess is located being defined by two flanks forming an angular notch and a third flank, the third flank being defined by a steel plate that forms at least part of the respective jaw cheek, the steel plate being fixedly connected to the first wide side of the head, the steel plate provides torque transmitting engagement on the nut or the bolt head; the two flanks forming a multi-point configuration for partially surrounding engagement in a torque-transmitting manner on said polygonal profile; and the third flank forming a stop for a portion of an end-face of said polygonal profile and is located on a boundary line between the first and the second wide sides.
