Drehmomentschlüssels

A Drehmomentschlüssel, also known as a torque wrench, is a tool used to apply a specific rotational force, or torque, to a fastener such as a nut or bolt. This precise application of force is crucial in many assembly and repair processes to ensure that fasteners are tightened to the correct specification. Over-tightening can lead to stripped threads, damaged components, or even catastrophic failure, while under-tightening can result in loose connections and potential operational problems.

Drehmomentschlüssel come in various types, each with its own mechanism for indicating or setting the desired torque. Common types include click-type wrenches, beam-type wrenches, and digital wrenches. Click-type wrenches emit an audible and tactile click when the set torque is reached. Beam-type wrenches use a flexible beam that bends, with a pointer indicating the torque on a scale. Digital torque wrenches provide a numerical display of the applied torque and often offer additional features like memory storage and audible alarms.

The selection of a Drehmomentschlüssel depends on the required torque range, accuracy needed, and the specific application. They are widely used in industries such as automotive, aerospace, manufacturing, and construction, where precise assembly is critical for safety and performance. Regular calibration of a Drehmomentschlüssel is essential to maintain its accuracy and ensure consistent results.
