Torque wrenches allow precise control of the tightening force of threaded connections. They are ordered for work where it is important not just to tighten the fasteners, but to do it with a given moment in order to avoid understretching or damage to the part. Such tools are widely used in car service (for example, for installing wheels or for assembling a car engine), mechanical engineering, construction and other industries.
Types of torque wrenches
There are several main types of moment keys, and each of them is suitable for its own tasks. Snap (limit) is an inexpensive mechanical tool that gives a characteristic click when a given force is reached, which makes operation fast and convenient.
Digital (electronic) models are characterized by high accuracy and advanced functionality: they can have sound and light indications, a display and the ability to save data on the completed puff. The arrow keys (scale) show the current force in real time, which makes them suitable for precise control of the tightening torque.
What to consider when buying a torque wrench
- The operating range of the moment. The tool must match the required tightening values: from precise work in the range of 1-25 Nm to heavy tasks with a force of over 1000 Nm.
- The connecting square. Common sizes - 1/4", 3/8", 1/2", 3/4" and 1". The higher the load and the larger the fasteners, the larger the square should be.
- Accuracy. For accurate work, the minimum error is important - usually ± 3 or ± 4%.
- The adjustment mechanism. Models with a spring system, a locking ring for fixing the value and a reversible ratchet for more comfortable operation can be ordered.
- Handle material. Oil-resistant rubber improves grip and reduces slipping, and the metal handle is strong and durable.
Errors in the operation of torque wrenches
It is not recommended to use extension cords and additional levers, as they change the leverage and distort the actual tightening torque. The fasteners must be tightened smoothly, without sudden jerks, otherwise the risk of exceeding the setpoint increases.
