What are the different types of screws?

Screws are fundamental fastening elements in DIY work. There is a wide variety of different types that differ in terms of shape, material, and application areas. Here are some of the most common types:

• Wood screws: They have a coarser thread and are mainly used for wood joints.
• Metal screws: They have a finer thread and are primarily used for joining and fastening metal parts.
• Machine-thread screws: They are screwed into pre-drilled threaded holes and are often used in machinery and vehicle construction.
• Countersunk screws: They have a flat head that can be sunk flush into the material. This ensures a clean, smooth surface.
• Torx screws: They have a special star-shaped drive that enables better force transmission and prevents the tool from slipping.
• Self-drilling screws: These screws have a drill point and cut thread, so they can be used without pre-drilling – especially in thin metal sheets.

The choice of the right screw depends on the material, the fastening technique, and the visual requirements. For special applications, specific screw types may be required.
