torquímetros

Torquímetros are precision instruments used to measure and apply a specific rotational force, known as torque, to a fastener like a bolt or nut. This precise application of force is critical in many assembly processes to ensure components are tightened correctly, preventing over-tightening which can cause damage or under-tightening which can lead to failure.

There are several types of torque wrenches. Click-type torque wrenches are perhaps the most common. When the set torque is reached, they produce an audible click and often a slight physical release, signaling the operator to stop applying force. Beam-type torque wrenches use a deflection indicator or needle that moves along a calibrated scale as torque is applied. Dial torque wrenches, similar to beam types, feature a dial indicator to display the applied torque. Electronic torque wrenches offer digital readouts and can often store torque data, providing a higher level of accuracy and traceability.

The proper use of a torque wrench involves setting the desired torque value, then applying smooth, steady pressure until the wrench indicates the target torque has been reached. It is important to avoid jerky movements and to ensure the wrench is correctly engaged with the fastener. Calibration of torque wrenches is also essential to maintain their accuracy over time and with repeated use. Regular calibration by a qualified service provider ensures the wrench continues to measure and apply torque within its specified tolerances. Torque wrenches are indispensable tools in automotive repair, aerospace manufacturing, and any field where precise fastening is paramount.
