Solid rivets are cylindrical metal fasteners used to join two or more pieces of material together. They are typically made from materials like steel, aluminum, or copper and are installed by inserting the rivet through pre-drilled holes and then deforming the end to create a secure connection. This process is often done using a hammer or a specialized tool. These fasteners are commonly used in various industries, including aerospace, construction, and automotive manufacturing. Solid rivets provide strong, permanent joints that can withstand high levels of stress and are resistant to vibration, making them ideal for applications where durability is essential.
