The roller rivet (also known as the pull rivet) is a mechanical fixture that secures two or more materials firmly by forming a plastic deformation in the connecting material. Compared with traditional rivets, roller rivets have stronger fixation ability and are suitable for more application fields.
The structure of the roller rivet is divided into two parts: pull nail and shell. The pull nail is a long strip of metal rod with a head and a tail. The head positions when inserting the material; the tail stretches vigorously when fixing the material. The shell is a metal tube that can be cylindrical, flat or other geometry. It is the main part of the connecting material.
