Bolted joints are mechanical connections that use bolts to hold two or more components together. They are commonly used in construction, machinery, and automotive applications due to their strength and reliability. The bolt passes through aligned holes in the components and is secured with a nut, creating a tight fit that can withstand various forces. The effectiveness of a bolted joint depends on factors such as the material of the components, the size and grade of the bolt, and the torque applied during installation. Properly designed and installed bolted joints can provide a strong and durable connection, making them essential in many engineering applications.
