RivetsRivets are fasteners that are used to join two or more pieces of material together. They are typically made of metal and have a cylindrical or mushroom-shaped head on one end and a tail on the other end. Rivets are inserted through holes in the materials to be joined, and the tail is then flattened or upset to form a second head, securing the rivet in place. Rivets are commonly used in a wide range of applications, including construction, automotive, and aerospace, where they provide strong, permanent joints that can withstand high loads. Rivets are available in a range of sizes and materials to suit different applications.
