Bolted joints are connections made by fastening two or more components together using a bolt and a nut. This method is commonly used in construction and machinery because it provides a strong and reliable connection. The bolt is inserted through holes in the components, and the nut is tightened onto the bolt, creating a secure joint. These joints can be easily assembled and disassembled, making them versatile for various applications. Proper torque is essential to ensure the joint remains tight under load. Bolted joints are widely used in structures like bridges, buildings, and vehicles due to their strength and ease of maintenance.
