dreiemomentsnøkkel

A dreiemomentsnøkkel, also known as a torque wrench, is a tool used to apply a specific amount of rotational force to a fastener, such as a bolt or nut. This precise application of torque is crucial in many mechanical and automotive applications to ensure that components are tightened correctly and not over-tightened or under-tightened. Over-tightening can strip threads or damage parts, while under-tightening can lead to loosening and potential failure of the assembly.

Dreiemomentsnøkler are available in various types, including click-type, beam-type, and digital wrenches. Click-type wrenches audibly click when the preset torque is reached, providing clear feedback to the user. Beam-type wrenches use a deflecting beam to indicate the applied torque on a scale. Digital torque wrenches offer electronic displays for precise readings and often include features like data logging and audible or visual alerts.

The selection of a dreiemomentsnøkkel depends on the required torque range and the precision needed for the specific application. They are essential for assembling engines, bicycles, aircraft, and many other precision engineered products where consistent and accurate fastener tension is vital for safety and performance. Regular calibration of a dreiemomentsnøkkel is important to maintain its accuracy over time.
