explosive rivet

An explosive rivet is a type of blind rivet used for fastening when access to the back of the material is limited. It contains a small, heat-sensitive explosive charge within its hollow shank. When heat is applied to the rivet's head, the charge detonates, expanding the shank tightly into the hole, creating a secure fastening.1

These rivets are often made of aluminum but can also be found in stainless steel and other metals. Their primary application is in the aircraft industry, particularly for attaching the aluminum skin to airplane wings, where conventional riveting might be impractical. While the explosion can be noisy, the shank can be sealed to reduce noise and prevent metal fragments from being ejected.12
