Drill tail screws are a new invention of people in recent years. As the name suggests, the tail of the screw generally takes the shape of a drill tail. Drill tail screws are a type of wood screws, mainly used for fixing color steel tiles in steel structures, and can also be used to fix thin plates in simple buildings. The tail of the drill tail screw is in the shape of a drill tail or a pointed tail. No auxiliary processing is required. Drilling, tapping and locking can be directly performed on the setting materials and basic materials, greatly saving construction time.

Compared with ordinary screws, self drilling screws have higher toughness and retention force, and will not loosen for a long time after being combined. Use, safe drilling, and tapping can be completed in one go, and the operation is simple.

Due to the essential difference between stainless steel and carbon steel, stainless steel has better extensibility. If used improperly, it is easy to cause the screw to fail to penetrate smoothly and the bonding force is not strong. Therefore, when using stainless steel drill tail screws, you need to pay attention to:

1. Before use, confirm whether the mechanical properties of the product meet the usage requirements.

For example: SUS316 and SUS304 screws can only penetrate plastic steel, magnesium titanium alloy, aluminum alloy, industrial plastics and other materials. SUS410C drill tail screws can not only penetrate the above materials, but also stainless steel plates and various materials with a hardness of Steel plate with HV around 300 degrees. (steel plate below 18mm)

2. Choose different drill tail screws according to the use environment.

3. Choose different models and specifications of drill screws according to different materials and thicknesses. For example: choose longer drill tail screws when tapping thicker materials.

4. When tapping, keep the axis of the lock and the axis of the screw on the same straight line and tap into the locked object vertically.
