Guide to buying screws

 

The screw is an essential element when anchoring furniture to the walls, but it also has many other uses both at home and in workshops, since depending on its structure and material, it can be used to fix plastic, metals, concrete, between others. However, it can be difficult to choose from the wide variety of models that currently exist, for this reason we have created this small guide to buy the best screw, so that you have access to the most important information about this fastening device.

Shopping guide

Stem

In the first place, it is important to take into account the work that we are going to do, especially to correctly choose the measures of the stem, that is, the diameter and length of the body of the screw, since this will be introduced in the material and in some cases could negatively affect its structure.

When comparing screws, it is common to see the letter M between the stem measures, which corresponds to the external nominal diameter of the thread, in other words, the nomenclature M4 means that the screw has a diameter of 4 mm, that is why You must first define the width of the holes or plugs and the type of material you are going to use. For example, if you have a thin piece of wood, a very thick stem is not recommended, since you could break it.

There are self-tapping screws, which have a thread specially designed to pierce the material as you press, turning on its own axis. These fasteners can create a thread in the wood as they go, so it is not necessary to use a drill beforehand to open a hole. On the contrary, the screws called sheet thread do need a hole before being introduced, although they can also generate their own thread in the material at the time of installation.

Some of the most popular screws today are those that are shaped like a drill at the tip of the stem, which allows drilling and adjusting in one movement with the electric screwdriver. 

Head

You may be wondering how much a screw costs, but before checking the prices it is important to define what type of head is more convenient according to the project you are going to do. The most common are flat, hexagonal and countersunk, as they work for many applications in the home, although there are also screws called prisoners, which have no head. 

The flat head is very useful when we need that the surface of the material is not affected by the protuberances that other screws can leave. In this case, the head can be almost level with the wood, so we get a cleaner and more professional finish. However, this type of head is not embedded in the material.

Hexagon head screws are usually more robust, so they are used to fix the bases of heavy objects, for example, if you want to anchor an electric thermos to the wall. In addition, you can screw them with flat wrench, which allows a higher level of adjustment.

The countersunk head can be completely hidden in the material, for this reason, it is indicated for woodwork, whether carpentry or crafts at home. On the other hand, headless screws may be convenient to hold two parts of the same piece, without any risk of movement, since these screws remain internal and you usually need an Allen key to be able to remove them. 

Paw print

The fingerprint is the slot that has the screw in the head, through which you can insert it or remove it from the piece using a hand or power tool. One of the most common is the cross or Phillips footprint, which allows a centered screwing and is used in different industrial sectors and for domestic repairs.

On the other hand, the torx footprint has a star shape and allows greater coupling of the pieces for optimal support. Something similar occurs with the Allen footprint, which has a hexagonal shape and allows the use of L-shaped wrenches, which allow a higher tightening torque without damaging the screw tip.

Even if you want an economical screw, we recommend that you take these fundamental characteristics into account, since this depends on your investment having good results. Also important is the manufacturing material, which should be stainless steel to resist corrosion and oxidation. Some screws even have a zinc coating for a longer life.

Frequently asked questions

Q1: How to remove a last screw?

Sometimes we think that there is no solution for a past screw, that is, that the attempt has been erased so much from trying, either because it was one of poor quality or because we have not used the tools correctly. There are several alternatives to remove it, one of them is with an elastic band, since this provides us with some support in the areas where the metal is insulated, you just have to place the band on the drill and pull it before applying force to the screw. Now, if the head of the screw protrudes a little you could tighten it with the chuck of the electric drill, tighten and operate the device to remove the screw.

Q2: How to loosen a rusty screw?

When a screw is oxidized, it is usually stuck in the part and the inability to remove it with the screwdriver can generate a lot of stress. However, there are substances that can help us remove and dissolve the accumulated oxide by loosening the screw and allowing its extraction. One of them is the cola soft drink, since it has a small amount of phosphoric acid, which together with water and carbon dioxide, allows to dilute the oxide, although you must leave it to act for about 12 hours, this can also be achieved with edible vinegar and even mixing salt and lemon juice.

Q3: How to use a screw?

The screw is one of the easiest fasteners to use, since it consists of a head with a stem and a tip. The first thing you should do is make sure that the screw is compatible with the materials you want to drill and adjust. In some cases, it will be necessary to open a hole with a drill first, using a bit slightly thinner than the screw, so that it is well adjusted when screwing. On the other hand, self-drilling screws can drill the wood and create its own thread while screwing it without using the drill. To install brackets on the walls and ceilings you will usually also need plastic studs compatible with the screws.

Q4: How to know the tightening torque of a screw?

If you want your screw to have the perfect fit, then you must know its tightening torque. This is particularly important in the automotive industry, since the parts are usually very delicate. For this there are reference tables, where suggestions appear, depending on the diameter of the screw and the pitch, that is, the distance between the crests of the thread. This is a complex but exciting topic, so we invite you to continue researching it.

Q5: How to remove a screw that turns but does not come out?

This depends on many variables, such as the type of material where it is screwed, also, the type of screw that includes the head and footprint. However, it is a common problem that a screw embedded in plastic rotates continuously without leaving, especially if it has been forced into a hole that did not match the thread. In these cases, the footprint and head are generally intact and yet it is not possible to unscrew, so it is necessary to use a copper wire surrounding the screw just below the head, to be able to pull it with some force as you turn counterclockwise using a screwdriver.
