Pop Rivets (also known as Blind Rivets) are fasteners used to join two or more materials together. Unlike traditional rivets, pop rivets can be installed from only one side of the material, making them ideal for situations where access to both sides of the workpiece is limited. They consist of a smooth, cylindrical body and a mandrel (the central stem), which is pulled through the rivet body to expand it and securely hold the materials together. ... Pop rivets are widely used in automotive, aerospace, construction, and manufacturing industries for attaching materials such as metal, plastic, or wood. They come in various materials, including aluminum, steel, and stainless steel, and are available in different sizes and lengths to suit a range of applications.
