Abstract: A rivet apparatus is provided for securing together a first element to a second element made of solid metal. The apparatus comprises a support 3 which is common to the first element and to a hollow charge 4. A metal rivet or nail 5 embedded in the charge of the hollow charge, in the axis of a liner 6 of the hollow charge 4. The support 3 has a surface 7 intended to be applied against a second hard metal element 2 and approximately centered on the focal point F of the hollow charge 4. Upon detonation of the charge, the metal rivet or nail 5 enters the second element 2 thereby binding first and second elements together.
