vääntömomenttiavaamia

Vääntömomenttiavain, commonly known in English 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 force is crucial in many mechanical and engineering applications to ensure that components are tightened correctly, preventing them from loosening due to vibration or over-tightening, which can cause damage to the components themselves or the materials they are fastened to.

There are several types of torque wrenches, each designed for different applications and levels of precision. Common types include click-type torque wrenches, beam-type torque wrenches, dial-type torque wrenches, and digital torque wrenches. The click-type wrench is perhaps the most common, emitting an audible and tactile click when the preset torque value is reached. Beam-type wrenches utilize a deflection beam that indicates the applied torque on a scale. Dial-type wrenches use a dial indicator to show the torque, while digital torque wrenches provide a digital readout, often with electronic features like data logging and angle measurement.

The proper use of a torque wrench involves setting the desired torque value, then applying steady and continuous force until the wrench indicates that the target torque has been achieved. It is important to avoid jerking the wrench or exceeding the set torque, as this can lead to inaccurate readings and potential damage. Torque wrenches are indispensable in industries such as automotive repair, aerospace, and manufacturing where precise assembly is paramount for safety and performance.
