Self-adjusting wrenches, like fixed wrenches, are assembly tools made of materials such as stainless steel, which makes them highly resistant. Their function is to tighten and loosen screws and nuts, being useful to carry out different jobs.
Among their main features, we find that they are objects whose mouth has two parts: a fixed and a mobile one, which translates into greater precision, especially if we compare it with the fixed one.
In the specific case of the set of self-adjusting wrenches from Total, it is composed of two different tools:
