Rivets are permanent fasteners that join materials by means of a mechanical interlock. They consist of a cylindrical shaft with a head at one end and are installed by deforming the unheaded end after insertion. Rivets are commonly used in structural applications such as bridges and aircraft, where a high level of strength is critical. There are different types of rivets, including solid rivets, blind rivets, and tubular rivets. Blind rivets, also known as pop rivets, can be installed from one side of the workpiece, making them ideal for applications where access to both sides is limited.

The design of a bolt structure also involves careful consideration of its mechanical properties, such as tensile strength, shear strength, and fatigue resistance. Tensile strength refers to the maximum load a bolt can withstand while being pulled in tension, whereas shear strength is associated with the load bearing capacity when the bolt experiences forces perpendicular to its axis. Fatigue resistance is particularly important in structures subjected to repeated loading cycles, as it ensures that the bolt can withstand the wear and tear of regular operation without failure.
