DIN 928 Square Weld Nut

Square welding nut DIN928 is a fastener manufactured according to the German industrial standard DIN 928. The DIN 928 standard mainly specifies the thread size and type of welding nuts, mainly using metric threads, such as M threads, Tr threads and BSP threads. In order to ensure welding quality and connection reliability, the DIN 928 standard also specifies the welding area and thickness of welding nuts. According to the DIN 928 standard, weld nuts should have certain mechanical properties such as tensile strength and torque resistance. In addition, the standard also puts forward requirements for the corrosion resistance and wear resistance of the nut to ensure that it can maintain good performance in various environments. Square weld nuts have internal threads and are used with screws to transmit movement or power. There are three welding spots and circular bosses on one side. The bosses are used for positioning and the welding spots are used for welding. Square welding nuts are mainly used in automobile seats, sheet metal chassis/cabinets, ships, railways and other fields.
