momentnøkkel

A momentnøkkel, often translated as torque wrench in English, is a tool used to apply a specific torque to a fastener, such as a nut or bolt. This precision is crucial in many applications where over-tightening or under-tightening can lead to component failure or improper assembly. Momentnøkler are designed to indicate when a preset torque value has been reached.

There are several types of momentnøkler. Click-type wrenches are common, emitting an audible and tactile click when the desired torque is achieved. Beam-type wrenches have a pointer that moves along a scale, showing the applied torque. Digital momentnøkler provide a digital readout of the torque. These tools are calibrated to ensure accuracy and are essential in industries like automotive repair, aerospace, and manufacturing. Proper use and maintenance, including regular calibration, are important for their continued reliability.
