    The application of stud bolts and how to prevent moisture and rust

    Bolts are screws with larger diameters, and they can also have no heads, such as studs. Generally speaking, it is not called a "stallion" but a "stallion". The most common form of double-ended studs is threaded at both ends and a smooth rod in the middle. The most typical use: anchor bolts, or simil... read more

    High-strength bolt processing technology

    High-strength fasteners must be quenched and tempered according to technical requirements. Heat treatment quenching and tempering is to improve the comprehensive mechanical properties of fasteners to meet the specified tensile strength value and yield ratio of the product. The heat treatment process... read more

    Thread processing

    Bolt threads are generally cold worked, so that the thread blanks within a certain diameter range are passed through the rolling (rolling) wire plate (die), and the thread is formed by the pressure of the wire plate (rolling die). The plastic streamline of the threaded part is not cut, the strength ... read more

    Cold forming

    Usually, the bolt head is formed by cold heading plastic processing. Compared with cutting processing, the metal fiber (metal wire) is continuous along the shape of the product without cutting in the middle, thus improving the strength of the product, especially the mechanical properties. The cold h... read more

    High-strength bolt processing technology

    Drawing The drawing process has two purposes. One is to change the size of the raw material; the other is to obtain basic mechanical properties of the fastener through deformation strengthening. For medium carbon steel and medium carbon alloy steel, there is another purpose, that is, to make wire ro... read more
