What Is the Difference Between Self Drilling Screws and Ordinary Screws?

There are significant differences between self drilling screws and general screws in terms of usage, installation methods, materials, etc. Before choosing screws, you can first understand the differences in the following aspects to make a better choice.

1. Differences in application fields

Self drilling screws: They are designed to simplify the installation process. They are especially suitable for direct installation of metal sheets without pre-drilling. They are widely used in quick connections in building curtain walls, metal roof panels, automobile manufacturing and other fields.

Conventional screws: Due to their wide material compatibility and structural adaptability, they have become an indispensable component for connecting steel structures, wooden structures, concrete and other base materials. They are widely used in machinery manufacturing, construction engineering, furniture manufacturing and other industries. .

2. Comparison of installation techniques

Self drilling screws: Through the integrated drill bit design, the integrated operation of drilling and fastening is realized. The entire installation process can be completed using only an electric drill or hand drill, which improves work efficiency.

Conventional screws: The installation process is relatively cumbersome. It usually requires using a drill to drill holes accurately, and then screwing the screws into the holes with the help of tools such as screwdrivers. This step-by-step operation not only takes a long time, but may also cause hole position deviation due to improper operation, affecting the installation quality.

3. Diversity of material selection

Self drilling screws: They are mostly made of carbon steel. Because of their high hardness and good corrosion resistance, they can maintain stable performance in harsh environments and meet the needs of specific scenarios.

Conventional screws: The material selection is more diverse. Depending on the application environment, stainless steel, copper, iron and other materials can be used to meet different strength, corrosion resistance and aesthetic requirements.

4. Subdivision of applicable scenarios

Self drilling screws: With their unique self-drilling performance, they are suitable for occasions that require on-site drilling and immediate tightening, such as on-site installation and maintenance of metal plates.

Conventional screws: are more suitable for scenarios with higher requirements on connection strength and durability, such as the assembly of heavy mechanical equipment and the fixation of building structures. In these situations, conventional screws provide a more reliable and durable connection.

5. Evaluation of usage effects

Self drilling screws: Efficient and accurate installation is achieved through integrated operation, reducing human errors and installation time, and improving work efficiency and installation quality. At the same time, its self-drilling design also reduces the skill level requirements for installers.

Conventional screws: Although the installation process is relatively complicated, they perform well in withstanding large loads and long-term use, and are an indispensable element in building a stable structure. However, its installation efficiency is low and susceptible to human factors, requiring higher operating skills and experience.
