Torque wrench with pre-set torque value for all applications where the same torque and repeat accuracy is required. The torque value can be changed within the metered range. The robust release mechanism guarantees a clearly audible and tactile trigger signal when the set torque value is reached. Square socket for interchangeable plug-in tools for clockwise and anti-clockwise torque-control. A presetting which deviates from this value to a desired torque value within the specified metered range is possible on request.
