The torque wrench is also called torquimetro or torquimetro. It is based on a key to which different caps can be adapted, which makes itvery versatile. It has an adjustment system, which allows to regulate the newtons of force, once said torque is reached, the tools have a system that causes the key to jump, not tightening and indicating that the screw or nut is tightened to the indicated force .

There are several models, the most common are:

1. Digital torque wrench Show the values ??on a screen, when you reach the torThe indicated pattern usually whistles or vibrates.
2. Torque wrench. The key stops tightening through a mechanical system, noticing a few jumps.
