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, metal, concrete, among others. others. However, it can be difficult to choose among the wide variety of models that currently exist, for this reason we have created this small guide to buy the best screw, with the aim that you have access to the most important information about this fastening device.
In the first place, it is important to take into account the work that we are going to carry out, especially to correctly choose the measurements of the shank, that is, the diameter and length of the body of the screw, since this will be inserted into the material and in some cases could negatively affect its structure.
When making a comparison of screws, it is common to see the letter M among the measurements of the shank, which corresponds to the nominal outer diameter of the thread, in other words, the nomenclature M4 means that the screw has a diameter of 4 mm, which is why that 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 split it.
There are self-tapping screws, which have a specially designed thread to pierce the material as you press by turning on its own axis. These fasteners can create a thread in the wood as they go, so there’s no need to drill a hole first. On the contrary, the screws called sheet metal thread do need a hole before being inserted, although they can also generate their own thread in the material at the time of installation.
One of the most popular screws today are those that have a drill shape at the tip of the shank, which allows drilling and tightening in a single movement with the electric screwdriver.
Perhaps you are wondering how much a screw costs, but before reviewing the prices it is important to define what type of head is more convenient according to the project you are going to carry out. The most common are the flat, hex and countersunk ones, as they work for many applications around the home, although there are also screws called grub screws, which have no heads.
The flat head is very useful when we need the surface of the material not to be affected by the protrusions that can be left by other screws. In this case, the head can be almost at the same level of the wood, so we get a cleaner and more professional finish. However, this type of head is not embedded in the material.
Hex 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 water heater to the wall. In addition, you can screw them with a flat key, which allows a higher level of adjustment.
The countersunk head can be completely hidden in the material, for this reason it is suitable for woodworking, whether carpentry or home crafts. For their part, headless screws can be convenient for holding two parts of the same piece, without there being a risk of movement, since these screws are internal and you generally need an allen key to remove them.
The footprint is the slot in the head of the screw, through which you can insert or remove it from the part using a hand or power tool. One of the most common is the cross or Phillips footprint, which allows centered screwing and is used in different industrial sectors and for home repairs.
On the other hand, the torx footprint is star-shaped and allows greater coupling of the pieces for optimal clamping. Something similar happens with the Allen footprint, which is hexagonal in shape and allows the use of L-shaped keys, which allow a higher tightening torque without damaging the tip of the screw.
Even if you want an economical screw, we recommend you take these fundamental characteristics into account, since it depends on this that your investment has good results. The manufacturing material is also important, which should be stainless steel to resist corrosion and oxidation. Some screws even have a zinc coating for longer life.
Frequently asked questions
Q1: How to remove a screw passed?
Sometimes we think that there is no solution for a worn screw, that is, that from trying so hard the trace has been erased, either because it was a poor quality one 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 gives us a little support in the areas where the metal is isolated, you just have to place the band on the bit and pull it before applying force to the screw. Now, if the screw head sticks out a little you could tighten it with the chuck of the electric drill, squeeze and activate the device to remove the screw.
Q2: How to loosen a rusty screw?
When a screw rusts, it usually gets stuck in the part and the inability to remove it with the screwdriver can cause a lot of stress. However, there are substances that can help us remove and dissolve the accumulated rust by loosening the screw and allowing it to be removed. One of them is cola soda, since it has a small amount of phosphoric acid, which, together with water and carbon dioxide, allows the oxide to be diluted, 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, as it consists of a head with a shank and a point. The first thing you need to do is make sure the screw is compatible with the materials you want to drill and fasten. In some cases it will be necessary to first open a hole with a drill, using a bit slightly finer than the screw, so that when screwing it is well adjusted. On the other hand, self-drilling screws can pierce the wood and create its own thread while screwing it in without first using the drill. To install supports on walls and ceilings, you will usually also need plastic plugs compatible with the screws.
Q4: How to know the tightening torque of a screw?
If you want your bolt to have the perfect fit, then you need to know its torque. This is particularly important in the automotive industry, as parts are often 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 it is screwed into, as well as the type of screw that includes the head and footprint. However, it is a common problem that a screw embedded in plastic turns continuously without coming out, especially if it has been forced into a hole that did not correspond to the thread. In these cases, the tread 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, in order to be able to pull it with some force as you turn. counterclockwise using a screwdriver.
