Rivets are a type of permanent mechanical fastener used to join two or more materials together securely. They consist of a head on one end, a cylindrical shaft, and a tail that expands to create a second head once installed, holding the materials in place. Their main functions include providing a strong joint, being lightweight, and not requiring access from the back of the components they are connecting. Rivets are commonly used in applications where reliability and durability are crucial, such as in the construction of aircraft, bridges, and various types of machinery. Characteristics of rivets include their various sizes, materials (such as aluminum, steel, or plastic), and head styles, each tailored for specific strength requirements and installation scenarios.
Some well-known manufacturers that produce various types of rivets include Stanley Engineered Fastening (POP Rivet), Cherry Aerospace, and Arconic (formerly known as Alcoa). These companies are recognized for their quality and variety, supplying rivets to various industrial sectors.
