Zhuocheng Aluminium Tri-Fold Blind Rivets Black Painted

Tri-fold rivets are used for various applications, including attaching sheets, panels, and other materials to metal frames. They are commonly used in the automotive, aerospace, and transportation industries, where fasteners are required to withstand severe conditions. The tri-fold rivet design provides greater flexibility and strength to support heavy loads and resist vibrations. They are also ideal for applications where other rivets may not fit or hold correctly.

Using tri-fold rivets requires specific tools and techniques. A drill or punch creates a hole in the materials to be fastened. The hole should be slightly smaller than the rivet’s diameter, and care must be taken not to damage the surface of the materials. The rivet is inserted into the hole by a gun, and the mandrel is pulled back to compress the rivet’s legs. As the mandrel snaps off at the point of tri-fold, the rivet forms a secure and tight grip around the fastened materials. A nail or punch can help loosen the mandrel if it snaps off inside the rivet before pulling it out.
