    How to choose a suitable self tapping screw

    1. Select by material: Select different self tapping screws based on the material characteristics that need to be nailed in. For example, for hard materials, choose self tapping screws with high strength, appropriate length and diameter.

    2. According to thread selection: Self tapping screws usually have two types: coarse thread and fine thread, and different threads are usually suitable for different materials.

    3. Select according to the shape of the head: The pentagonal head self tapping screw is more sturdy than the ordinary round head self tapping screw, but the price is also relatively high.
