Rivets are a type of mechanical fastener that achieves permanent connection of components through their own plastic deformation. Their core characteristics are non-removability, reliable connection, and vibration resistance. Based on their structure, installation process, and application scenarios, they can be mainly divided into the following categories: Solid rivets are the most traditional type, requiring forging at elevated or ambient temperatures to expand and form the tail of the rivet shank. They are widely used in high-strength applications such as steel structures and aerospace; blind rivets (pull rivets) utilize a special riveting tool to expand the rivet body by pulling and breaking the mandrel, making them particularly suitable for enclosed or thin-plate structures where only single-sided access is possible; and drive rivets expand by striking the exposed end of the mandrel, offering easier installation. In addition, there are special types such as Huck rivets, which provide extremely high shear and tensile strength. Each type of rivet has its own characteristics in terms of connection strength, installation efficiency, applicable hole diameter, and material compatibility, making them a crucial basic fastening solution in industrial manufacturing.
