The nuts have a threaded hole.
A nut is an element that has a threaded hole. This characteristic allows a screw to attach to its structure, threading.
For example: "The table is moving a lot: I'm going to have to adjust the nuts" , "I'm trying to assemble the desk we bought but I can't find the nuts" , "I think this machine is missing some nuts" .
Function of a nut
The purpose of a nut is to promote the union between different objects. When a nut and a screw fit together, they are secured. To make this possible, the nuts are standardized according to a general system, so that the screws fit without problems in the hole of a compatible nut.
Many times the nut and screw also interact with a washer . This piece , similar to the nut but of a very thin thickness and without thread, gives greater strength to the union, minimizing displacements.
When a screw is coupled to a nut, it favors the union of different elements.
Main features
Several fundamental characteristics can be recognized in any nut. One of them is the thread type, which defines which screw can be used with the part.
The diameter and thickness are also important. Nuts, on the other hand, can have four or six sides depending on the design.
The nut wrench
The wrench is a tool used very often in manufacturing and assembly tasks, both in the commercial field and at home. In short, its main function is to tighten and loosen nuts, and that can be seen by observing its tip , cupped with the exact shape of the nut for which it has been designed.
Its use is quite simple: you slide the tip of the wrench so that the nut enters it and then you turn it in the direction corresponding to the desired task, tightening or loosening. The nut wrench is made from two different materials: the handle can be made of tempered plastic or rubber, always seeking the greatest possible resistance ; the rest of the body and the tip are always made of steel.
Although the most common are hand tools , there are also wrenches that require the use of a drill, as they act as drill bits. These models allow more efficient and precise work, in addition to reducing user fatigue.

The term nut in different expressions
On the other hand, in a similar way to phrases that include the term screw to refer to someone's lack of sanity ( "he is missing a screw" , for example), it is possible to use the word nut with the same meaning: to say that A person "has a loose nut" is the same as implying that we doubt his mental faculties. This can also apply to a project, to point out that the details still need to be worked on before it can be considered solid .
There is another expression, "tightening the screws" on a person, which is often used as a synonym for pressuring someone to act in a certain way or to do something that they do not genuinely want or do not know how to do, especially if the way of persuading them It is rigid and severe. «If we want Jorge to improve his performance we are going to have to tighten the screws» , «I'm going to tighten the screws and you'll see how he changes his mind» .
