When most people think of riveting, they think of the classic blind rivet-the two-piece fastener consisting of a headed, hollow rivet body and a solid mandrel. However, riveting actually encompasses a wide range of technologies, including impact rivets, self-piercing rivets, self-clinching fasteners, rivet-nuts, and orbital and radial forming. Each has its own niche, its own advantages and limitations. Which to choose depends on the application.
