Of course there is no single model of screw, each of them must conform to the type of material on which it is going to intervene. Commercially they are available numerous types of screws for any professional use, and in order to choose the one most suitable for the type of work that will be carried out, several factors must be taken into consideration.
How to choose a screw based on its function
Each material has its own screw, just as each screw has its use. There thread, in particular, it is one of the fundamental characteristics when it comes to choosing a screw. The fillet is present along the stem of the vine, and consists of a series of furrows, which go to wrap around helically around the body of the same, and vary according to the use of the same.
there components which are extremely pointed, and which bear along the entire length a thread able to penetrate through the material, without the need to drill the surface previously. These screws will therefore be particularly suitable for soft materials such as wood or plasterboard, and can also be inserted without the help of a mechanical support such as, for example, a screwdriver.
Keeping the thread, but by changing only the material with which each piece is manufactured, these particular screws can also be used for sheet metal or "soft metals" such as aluminum, or even for plastic and iron.
The shape of the head
Then there is another component that determines both the use of the screw and the tool for its fixing, and it is the forehead. It is that section of the screw that allows the application of different types of pressure e force, based on the support that will then have to welcome it. There forehead has a different shape engraved on it each time, suitable for housing the tip of the fixing tool, whether it is a screwdriver or screwdriver electric. Depending on the material of the support on which you intend to intervene, it is possible to choose from time to time a head capable of penetrating inside, or remaining on the surface, and therefore visible.
The right screw at your fingertips
For the professionals who deal with woodworking, for example, you must always have them available the right vine for any type of use. Assembling some kind of furniture, or complement, without having applied the right screw, combined with a washer of adequate size, could cause the screw to lose adhesion, and lead to the collapse of the structure.
any professional type work, therefore, it is always necessary that the toolbox is well supplied, and that there is every type of screw, threaded rod, nut or washer, only in this way will you be sure that you have created a truly solid construction .
