1. The main difference is that the tooth pattern and the way of use are different. The wood screw is specially designed for hitting the wooden material, and the self-tapping is generally connected to the iron plate and the plastic.
2. Wooden nails are a kind of Tapping screws, which are generally used to fix wood. The main shape feature is wide tooth spacing. One of the ways to distinguish the use of Tapping screws is to look at the pitch. Generally, the smaller the pitch, the higher the strength of the fixed base material.
3. The main difference between self-tapping screws and wood screws is that the teeth are different and the surface hardness is different. The teeth of self-tapping screws are denser than wood [screw teeth, and the surface is harder, and the application range of self-tapping screws is also higher than that of wood screws]. wide.
4. The distance between the teeth and the cusp angle and the angle of the tooth pattern are different
