Common causes of failures in the industrial bolt and nut connections

Bolt and nut connections are widely used in various industries such as automotive, aircraft, and construction, etc. as a reliable method of connecting parts. In fact, this method has advantages such as ease of installation, ability to separate, and reuse compared to other connection methods like welding, gluing, or riveting. Industrial bolts and nuts are made using different technologies, including hot forging, cold forging, and machining, each of which has its own advantages and limitations and should be selected according to the connection application and working conditions. In addition, manufacturing processes directly affect the mechanical properties and performance of joints, making it essential to understand their implications for potential weaknesses and failure modes. Because the quality and performance of these connections significantly affect the strength, stability, and lifespan of the main structure, and this …
