Rivets are a small, lightweight type of fastener without threads that are most commonly used to permanently secure two materials together, although they can be removed if needed. A rivet is made up of a cylindrical shaft inserted through a pre-drilled hole, a fixed head and a tail that is passed through the body of the rivet using a specialized tool, the pop-rivet gun. Once the tail has been placed, the pop-rivet gun compresses it to fit over the opening, fastening the rivet securely in place.
Rivets are one of the most cost-effective, durable and strong fasteners available, often used for securing thin materials like gauge metal together. Common uses for fastening rivets include duct work, aluminum siding, home construction, sign assembly, woodworking and even aerospace manufacturing.
