In this section we are going to tell you everything you need to know about Self drilling screws. What kind of screws are self-Drilling screws? How and in what cases this type can be used and how they are made. So stay tuned.

What are Self-Drilling Screws?

These screws have a design similar to tools  such as Drills. As the name implies, to use this type of screw, they do not need to make a hole or drill to perform as a clamp, and they can be used without making a hole.

The performance of automatic screws is slightly different from other screws, and depending on the conditions for its use, we must consider the speed, depth and material of the material we want to use.

This type of screw is mostly used for working on mild steel, wood or metals.

In the picture above, we can get acquainted with the different parts of a self-Drilling screw. The upper bouts featured two cutaways, for easier access to the higher frets. What makes the difference in these turns is the end of the screw.

Notes on the use of self-Drilling screws

When deciding to use self-Drilling screws, the first and most important thing to consider is what material the contact screw is made of.

In addition to the above, we should mention key points such as the flute end groove, the end length of the flute and the side wings.

How self-drilling screws are used.

Self-drilling screws are very useful and can even be said to be versatile and have been used for drilling in various materials for many years.

Since these screws do not require making a hole or drilling, they increase the speed of work and increase the efficiency and performance by performing the connection operation in the best way.

When are Self-Drilling screws used?

A Note:

It is important to mention here that many people confuse the two types of self-tapping and self-drilling screws with each other or think that they are the same. But you should know that these two screws are different from each other in terms of structure.

The difference is at the bottom part of these screws.

self-drilling screws have a curve in them that makes it look like a twist drill used in drills; But self-tapping can have a flat, pointed or flat end.

What are self-drilling screws used for?

  • Building roofs

These screws are the best option for building metal roofs when used with washers. Self-drilling screws with washers have the ability to create a very strong clamp and seal. So if you want to build a metal roof for your home or to assemble or connect different components of the back structure, you can use this screw. This type of screw has become a valuable tool in construction for the reasons mentioned above.

  • Construction

These screws eliminated the need for builders to make holes and reduced the time required to do their work by a quarter. Construction without self-Drilling screws becomes very difficult.

  • Sheet Metals

These screws are very useful when we are going to use sheet metal, especially for all kinds of framing, and this is important because it speeds up the work and creates strong connections. These screws, with their strength, can pierce metals of different thickness and hardness. The ability to drill these screws varies depending on the type.

  • Medical use

It may not be very important to you, but if we want to know the wide range of efficiency of this screw, I must say that this screw is also used in the fields of medicine, orthopedics, tissue replacement and muscle repair.

  • Use against concrete Pillars

Self-drilling screws have the ability to penetrate or strike concrete, bricks and blocks. Of course, these screws have certain sizes and diameters that you can choose the best one using the experience and knowledge of an expert. Self-drilling screws for concrete have different styles, among which we can mention flat or grooved head screws.

Advantages of using self-drilling screws

  • Screw end point material

Drilling screw tips are usually made of very hard carbon steel. These steels are more stable at high temperatures and are more resistant to abrasion. Coatings such as zinc can also sometimes be used to multiply their resistance to corrosion

  • Stability at high temperatures

Drilling causes friction and friction generates a lot of heat. If the drills do not have good heat resistance, they will die quickly.

  • Requires less force

Self-drilling screws require less force due to their structure, and in the end this less force solves many of the problems that arise in connecting two materials to each other.

Self-tapping screws are designed to penetrate multiple materials and to connect quickly and efficiently, and they are designed and configured in such a way that they put several materials together without the need for additional pressure or force.

Conclusion

Self-drilling screws have the appearance of a drill bit and do not require drilling. Because drilling is not required to use these screws, they can significantly increase drilling speed. The connections made by these screws are very strong. Keep in mind that to use these screws, you must be very careful in choosing the right type. If you are planning to use these screws and you are confused in choosing it, you can get help from us.
