Thin sheets of metal, plastic, or other materials can be clamped together from one side, by means of blind rivets, better known as pop rivets. A tubular rivet is inserted in a hole which is drilled onto two sheets. It is then clinched by withdrawing a nail found inside the rivet. These fasteners are installed with a manual, pneumatic or electric rivet gun, to connect metal and other pieces together. This rivet has a feature which is different from all others. It is painted black.
