The Difference Between Self Tapping Screws and Ordinary Screws


Qualitative distinction

Self tapping screws: With a unique drill bit design, you can drill holes directly with special power tools and complete the fixing work at the same time. The whole process is simple and efficient.

Ordinary screws: The heads are designed to be flat and the screw shape is standard. No special tools are required. Just an ordinary screwdriver can be manually screwed in. It is suitable for routine fastening needs.

Feature comparison

Self tapping screws: The unique feature is that they can directly squeeze out corresponding threads on the object being installed through their own threads during installation, thereby ensuring that the two are tightly connected and not easy to loosen.

Ordinary screws: usually adopt a flat head design with uniform thickness, suitable for objects that are pre-drilled and tapped to ensure that the screws can be firmly screwed in and fixed.

Differences in usage scenarios

Self tapping screws: Due to their special self tapping characteristics, they are often used to fix non-metallic or soft metal materials without pre-drilling or tapping, which is convenient and fast.

Ordinary screws: Ordinary screws are a better choice when they need to be fixed to hard non-metallic or metallic materials. It requires drilling and tapping preparation before installation to ensure that the screws can be screwed in correctly and play a fixed role.

In summary, there are significant differences in properties, characteristics and usage scenarios between self tapping screws and ordinary screws. It is crucial to choose the appropriate screw type according to specific installation requirements.
