It is known as rivet to the process and the Outcome of rivet (to hit the head of a nail to affirm it or, in a symbolic sense, to highlight what is expressed). A rivet is also a plug or nail type that is used to fix something.
Rivets o roblones, therefore, they are fixation instruments that allow the union of two or more elements. Its structure is formed by a stem and one head, larger in diameter than the rest of the rivet. To use it, the stem is inserted into what is to be fixed; the head, due to its size, will allow Union.
A rivet allows to link elements made of different materials in a simple and economical way. The joint that is forged through rivets is permanent: cannot be disassembled. Different is the case of screws which, on the other hand, tend to offer a greater resistance.
Although this is a fairly secure fastening mechanism, rivets can fail when smash or when I know they break. In those cases, the link between the fixed elements since the rivet cannot fulfill its function.
The advantages of using the rivet as a joining system are that, in addition to being an economical proposal as we have already mentioned, it allows joining pieces of different materials, which can be carried out when only one of the faces of those is visible or that you can tackle with two or more pieces. All this without overlooking either that it can be done in many different ways and using a great variety of different materials, according to the needs of each moment.
Specifically, we can establish that the different types of rivets include compression and blind rivets. The latter, in turn, are divided into threaded, expanded, with a stretching mandrel, with a guided pin …
All this without forgetting specific rivets such as open with broken stem, cloverleaf type, slotted, high resistance, expandable in T, high retention …
It should not be overlooked that rivets also have their detractors. They reject the use of this binding mechanism for the following reasons:
-The union that is achieved cannot be disassembled, which makes it difficult and even prevents its correct maintenance and cleaning.
-It is not a good alternative when working with what are pieces that have a more than noticeable thickness.
-As we have mentioned previously, it is also established that the resistance is lower than if the same union were carried out with other procedures or alternative systems.
In colloquial language, the term rivet is used with reference to underline or emphasize something: “The grandfather once again riveted his slogans against concubinage and relationships that are not formalized”, “The writer ended the speech with his now traditional rivet of the importance of education”, “Stop pushing the same thing: I’m sick of hearing you say those things over and over again”.
