   A rivet is a permanent mechanical fastener. Before being installed, a rivet consists of a smooth cylindrical shaft with a head on one end. The end opposite the head is called the tail. On installation, the deformed end is called the shop head or buck-tail. Because there is effectively a head on each end of an installed rivet, it can support ...

5. Hermetic seal - Wikipedia

   en.wikipedia.org/wiki/Hermetic_seal

   When the glass and the metal being hermetically sealed have the same coefficient of thermal expansion, a "matched seal" derives its strength from bond between the glass and the metal's oxide. This type of glass-to-metal hermetic seal is generally used for low-intensity applications such as in light bulb bases.

6. Riveting machine - Wikipedia

   en.wikipedia.org/wiki/Riveting_machine

   This action causes the end of the rivet to roll over in the rollset which causes the end of the rivet to flare out and thus join the materials together. Impact riveting machines are very fast and a cycle time of 0.5 seconds is typical. Example of a 4-step orbital rivet Diagram of how an orbital riveting works

7. Rivet gun - Wikipedia

   en.wikipedia.org/wiki/Rivet_gun

   The rivet gun is used on rivet's factory head (the head present before riveting takes place), and a bucking bar is used to support the tail of the rivet. The energy from the hammer in the rivet gun drives the work and the rivet against the bucking bar. As a result, the tail of the rivet is compressed and work-hardened.
