Wrench (1) for delivering maximum torque to an external part, characterised in that it includes at least one lengthened metal part (3) fitted with a fixed end (4) and a pusher end (5), that also includes a torque application head (6) on which the pusher end (5) acts, where the lengthened metal part (3) is able to bend when torque is applied with the wrench, and where the enlarged metal part (3) reaches a maximum bend that determines the maximum torque deliverable by the wrench (1). The wrench (1) according to the invention is easier to use than conventional spring-based wrenches as the force required to adjust the torque is minimal and unrelated to the torque value to which the wrench is to be set. It is also capable of delivering higher torque. |
