Drilling screw is a common fastener, widely used in construction, furniture manufacturing, automobile manufacturing, machinery manufacturing and other fields. It cuts a hole in the material and reinforces it by drilling into the material while rotating, and is called a self-tapping or self-drilling screw.
Drilling screws can be divided into several classifications according to their different characteristics and uses. The main categories are detailed below:
1.Material classification: There are many kinds of materials for drilling screws, the most common of which are carbon steel, stainless steel and aluminum alloy. Carbon steel is generally used where higher strength is required, while stainless steel is suitable for environments where corrosion resistance is required. Aluminum alloys are widely used in industries such as automobile and aircraft manufacturing because they are light and resistant to rust.
2.Classification of head shape: There are also many shapes of the head of drilling screws, such as round head drilling screws, round head large mouth drilling screws, semi-round head drilling screws, countersunk head drilling screws, etc. These different shapes of heads can meet different styles or needs. For example, the round head is suitable for installation on a flat surface, and the half-round head can be buried inside the material to maintain aesthetics.
3. Classification of drill tip types: The drill tip of the drill tail screw is also one of its important components, and different drill tips can be used for different materials and occasions. The common drill points are automatic injection type, tapered drill point, cutting drill point and so on.
4. Coating classification: In order to increase the corrosion resistance, rust resistance and aesthetic appearance of drill tail screws, a layer of coating is often applied to the surface. At present, the main coatings for drilling screws on the market include galvanized, chrome-plated, entrained glass fiber coating, black oxide and plastic spray coating, etc.
5.Size classification: Drilling screws can be divided into many different specifications according to different sizes and lengths, including diameter, length and other parameters to distinguish.
The above are the main classification methods of drill tail screws. As the needs of various industries are constantly changing and updating, the classification and types of drilling screws are also increasing and updating.
