There are a large number of types of screws and it can be very confusing to know exactly which ones we need in each occasion. For this reason, it is best to have a guide at hand that tells us in a simple way what exists and the types of screw heads that we can find. There are screws for wood and metal depending on the use you want to give them, but the first thing is to know how to classify them.

Screw types can be classified in many ways. You have to take into account the material they use, the type of head and then the thread they use.

The head is the top and widest part of the screw. It is the one we use to tighten and loosen using a screwdriver (or an Allen key). Then we have the elongated part of the screw, which is called the shank. In some screws there is a piece of this part that is smooth and without thread, and is called the shank or neck. Obviously the part with the folds is the thread. The tip is where the long part or stem ends.

 What are the screws made of?

As said, there are many screws that are used for different things. It is not about buying the first screw we see and using it for everything.

The most common screws that people use are the steel ones, which can have a zinc-plated finish. They are what are usually used inside houses and indoors, but not for outdoors. The reason is that they do not resist corrosion very well, although for interiors they do hold up well.

On the other hand, we have the brass screws that are usually used in places where the screw is visible. Being more aesthetic than the others we have discussed, they are used above all for decorative themes where the main material is wood.

Types of screw heads

Surely you have heard of flat screwdrivers and star screwdrivers. Some may not know what it is, but they refer to what the screw head is like. However, when we talk about what screw heads are actually called we have slotted (flat) and cruciform (star) heads.

Then we have the bolts that have a wider head, and are tightened with a custom wrench or wrench. These are hexagonal or square head screws, which are used mainly in structures. They are much more solid and resistant and withstand a lot of pressure to hold the structure or pieces where they are used.

We have talked about Allen keys before, but the truth is that the screws of this type are a category in itself. They are screws that have a hexagonal hole in the upper central part where the Allen key is inserted to tighten the screw. This type of head is used for a lot of things, both in small parts and larger structures that must resist a lot.

Finally, we have some screws that are used more in workshops and specialized custom screw supplier and they are the Torx head screws. To tighten and loosen this type of screw, an electric screwdriver is usually used. We are not talking about those that can be bought for the home, but rather more professional ones that are very powerful. These screws are designed to have a great fixation and security.

How do I know the types of screws I should use?

The most important thing for those who do not know much about screws is to know when and how to use them. We do not want to complicate things and therefore we will be brief and to the point. How to know the types of screws to use?

If what you want is to use it to screw pieces of wood or other material that is not very hard, you have to use metal screws. For wood, it is best to have a fairly wide pitch. When it comes to steel and other metals, the screws are usually made of steel. In this case, the thread pitch must be finer so that the fixation is better.
