Rivets
A rivet is a permanent mechanical fastener used to join two or more components in metalworking, aerospace, and construction. Rivet diameters typically range from 2 to 25 mm, with lengths from 6 to 150 mm. Materials include carbon steel, stainless steel, aluminum, or copper, often heat-treated or coated for corrosion resistance, providing tensile strength between 300 and 1000 MPa. Rivets can withstand tensile, shear, and combined loads, and are installed using manual or pneumatic riveting tools.
Structurally, a rivet consists of a cylindrical body, head, and tail, which deforms under pressure or impact to form a permanent joint. Rivets are manufactured as solid or hollow blind/pop types. Their mechanical strength and stability make them widely used in metal structures, vehicle bodies, aircraft, and industrial machinery, providing a secure, non-removable connection without screws or nuts.
