Screws are the most common in daily decoration. Screws are the most used tool. However, there are many types of screws. Different types of screws are different in use. The hardness of concrete screws is relatively strong. It is not easy to break when installed into the wall. Therefore, concrete screws are commonly used during decoration.
What is the difference between concrete screws and steel screws?
View in chemically aspect, concrete screws are steel screws. They have less carbon content than iron screws and have stronger hardness than iron screws. In terms of usage, concrete screws can be driven into concrete walls for fixing. Steel nails are steel wire products used to nail objects. The concrete screw is widely used in industry, agriculture, construction, civil and other fields. It is mainly used to fix objects with small axial separation force and small radial shear force. It is convenient to use and can be nailed rapidly.
There are many kinds of steel screws and different shapes. You can select according to different purposes and requirements. The main varieties are round screws, flat head screws, flat head screws, square screws, triangle screws, saddle screws, twist screws, shot screws, concrete screws, split screws, linoleum screws, and corrugated screws. The product name is generally determined by shape, purpose, or nailing method, and also distinguished by whether the surface has a coating (such as galvanized nails, smooth nails, etc.). The most widely used is ordinary round nails.
Concrete screws, commonly known as steel screws, are a kind of nails. They are made of carbon steel. The material is 45# or 60# steel. It is processed by wire drawing, annealing, nail making, and quenching, so the texture is relatively hard. Its function is to nail some harder objects that other screws cannot do. Since the material is very different from ordinary screws, and it is a special screw that used in special field. Concrete screws are very hard, thick and short, and have strong chiseling ability.
Concrete screws have many types such as sliding rods, straight lines, diagonal lines, spirals, slubs, etc. The common ones are straight lines or sliding rods types. According to different classification methods, concrete screws can be divided into: blackened concrete screws, bluish concrete screws, colored concrete screws, countersunk concrete screws, K-shaped concrete screws, T-shaped concrete screws, galvanized concrete screws and so on.
