How to choose the right torque wrench for your needs?

Torque wrench is a must-have for every mechanic today, and a professional workshop should even have several with different types. This tool achieves the highest efficiency in the industry and is increasingly valued by amateurs. Why? It ensures that bolts are tightened with the appropriate force, reducing the risk of over-tightening or under-tightening as specified by the manufacturer.

Tightening bolts, screws based on feeling can be risky, especially when it comes to engines, fuel injectors, spark plugs, and thin plastic nuts. Torque wrench helps us tighten with precision.

Choosing a torque wrench is not too difficult. Determine the torque limit of the bolt, the size of the bolt and nut, then we will choose the right head and socket for the most suitable tightening.

What is a torque wrench? Purpose of use?

A torque wrench is a tool used to measure specific torque. It is used to tighten bolts with an appropriate force, measure accurately, and adjust to suit the material and strength of the bolt or nut. With these features, it prevents bolts from being over-tightened or under-tightened, ensuring that the tightening force meets the manufacturer's standards.

Precision is essential, especially in areas where bolts are made of aluminum or aluminum and steel. In car engines, if we tighten the cylinder head incorrectly, we can damage the gasket, cylinder head, and even cause damage to the entire engine block. Torque wrench is also effective when tightening plastic screws and nuts, used to connect delicate plastic parts in interior design, engine covers, etc. Plastic screws and nuts are tightened with a small torque, so a torque wrench with 2-10 Nm torque helps ensure the safety of both the screw and the product, for example: YATO YT-0751 torque wrench.

Torque wrench is often underestimated. However, after using a torque wrench, we tighten the bolts on each wheel by hand to the correct torque. This allows us to easily remove the screw later, which is especially important when changing tires on-site, ensuring its longevity.
