Problems solved by technology

After the conventional bolts and nuts are tightened and matched, the anti-loosening effect is not good. When used in vibration situations, the fastening reliability cannot be guaranteed. Since the screw heads of the existing bolts cannot be replaced, if the screw heads slip again , the entire bolt needs to be scrapped, resulting in waste

Description

【Technical field】 [0001] The invention relates to the technical field of fasteners, in particular to the technical field of a slotted flat tail screw assembly. 【Background technique】 [0002] Fasteners are the most widely used basic parts, and are the general term for a class of mechanical parts used when two or more parts or components are fastened into a whole. There are many types and specifications of fasteners, each with different functions and uses, and the degree of standardization, serialization and generalization is extremely high. Among them, the cooperation of bolts and nuts is the most common type of fasteners. After the conventional bolts and nuts are tightened and matched, the anti-loosening effect is not good. When used in vibration situations, the fastening reliability cannot be guaranteed. Since the screw heads of the existing bolts cannot be replaced, if the screw heads slip again , the whole bolt needs to be scrapped, resulting in waste. 【Content of in...
