Screw bolts are generally defined as fasteners that are installed into materials using tools like hammers or screwdrivers. Screw bolts come in all sizes and shapes that each one has different features. Screw bolts are made of materials like steel, iron and other type of metals as well as wood and plastic.

Where can screw bolts be used?
The purity and quality of the materials are directly related to the quality of the screw bolts. Those made of good materials are not easy to twist off and have a better fastening effect. Common materials for making screw bolts include carbon steel, stainless steel, copper and copper alloy. The raw materials of grade 8.8 and above are low-carbon alloy steel or medium-carbon steel, which are formed by heat treatment.
Cold heading forming process requires high demands, which requires more sophisticated production equipment. The imported production equipment increases the cost and difficulty of screw bolts.
High-strength and high-precision screw bolts are often heat-treated to make them have better functions.
Some screw bolts are sometimes used in special environments, such as high-speed rail tracks. This highly vibrating environment requires them to be tightly hugged together to prevent loosening.
The screw bolts will form a fine oxide layer on the surface of the bolts during the appearance treatment to prevent them from being corroded and shorting the service life.
The main function of screw bolts is to connect two workpieces together and act as a fastening function. Screw bolts are used in general equipment, such as mobile phones, computers, automobiles, bicycles, various machine tools, equipment, and almost all machines.
Screw bolts help to hold things together, such as pieces of wood or metal. Compared to ordinary nails, they provide more strength and holding power. It can be noticed that it has an inclined plane wrapped around a cylinder. The screw bolt's head acts as a lever.
Screw bolts are indispensable industrial necessities in daily life from glasses and electronics to construction and transportation equipment. Screw bolts play an important role in industry.
Screw bolts are mostly used for steel structure projects with relatively large bearing capacity, such as civil building steel structure, bridge steel structure, and power station steel structure.
Screw bolts are fasteners for all sorts of construction projects. There are so many different types of screw bolts because different objects and materials need to be fastened.
Screw bolts are classified by the material they are used to fasten. You need concrete ones for fastening objects to concrete, wood screw bolts for fastening objects to wood, or drywall ones for fastening objects to drywall. No one screw bolt could serve as a one-size-fits-all solution.
