Definition & Meaning of "rivet gun"

What is a "rivet gun"?

A rivet gun is a tool used to join two pieces of material together by inserting a rivet, a small metal pin with a head, into a hole. The tool presses the rivet into place, creating a secure and permanent connection. Rivet guns are commonly used in construction, metalworking, and automotive repairs where welding or screws are not suitable. They are especially useful for fastening materials like metal or plastic and are available in both manual and air-powered versions, depending on the strength and speed needed for the job.
