A screw is a device used to fasten an object. It has an elongated and threaded body (blade) that is inserted into the surface and with a head that has grooves so that a tool can be used and thus exert the corresponding force for its fixing.
Screws are generally used in conjunction with bushings. Suppose a person wants to fix a mirror on the wall. First, he will drill a hole with a drill, then he will insert the pin. With the hub already installed, you will have to insert the screw into it: to do this, you will use a screwdriver that allows you to turn the screw little by little. Finally you will hang the mirror. Depending on their purpose, screws have different characteristics. The most common screws are made of metal for its strength. Screw heads also vary, so there are oval head screws, flat head Phillips (cross slot), and others.
Sometimes the screws are not inserted into a wall, but are threaded to secure different parts of the same mechanism or piece of equipment. This requires that the nuts and bolts have the right sizes to complement each other. It is difficult to think of an electronic device that does not have screws in its structure. That yes, many of the devices that we usually buy and use on a daily basis are built with components specifically manufactured by the company, to prevent us from disassembling them and altering their functionality, so it is not so common to see conventional screw heads on phones, consoles of video games and audio systems, for example. The main advantage of the screw as a component of a product is that it can be easily placed and removed, without causing any type of damage or wear on the surface. This does not happen, for example, with nails or glue. Companies like IKEA have popularized the sale of furniture by parts, which buyers must assemble following a series of simple instructions and using the components included in the box, many of which are screws, since these products are intended for assembly and disassembly, something ideal for people who tend to move frequently. Screw, for its part, is the name given in informal language to the specimens of the plants Helicteres guazumifolia and cedrelinga catenaeformis. Fusilli noodles are also known as screw noodles. In Argentina, colloquially, very intense cold is called a bolt: “What a bolt does it do! Luckily I warmed up”, “Remember to wear a coat: I think you’re going to get laid tonight…”, “I’ll never forget last night’s dust”.
It is also common to say that a person has “a screw loose” or “a screw is missing” to refer to their lack of sanity, whether it is chronic or an isolated situation; Also, this can be used to offend her or as a joke. Precisely, the analogy makes us think of a structure whose stability is compromised by the lack of a screw or by not having all of them adjusted correctly. Giro Sintornillos is the name given in some Latin American countries to one of the characters in the Rico McPato universe, Disney’s billionaire duckling. He is the most outstanding inventor in Duckland, and his most characteristic trait is to keep a good mood even when his creations do not give the expected results. His name is related to the expression “twist without screw”, which in the past was used with a meaning similar to that of the previous paragraph.
