rivetti

Rivetti is the Italian plural noun for rivetto, a type of mechanical fastener known in English as a rivet. In Italian usage, rivetti refers to rivets used to join two or more materials by deforming the rivet’s tail to form a second head, securing the workpieces. The term encompasses various rivet designs and sizes found in technical literature and industry.

Rivets come in several families. Solid rivets are made from a single piece of material and typically require access to both sides of the joint to form the second head. Blind rivets, or pop rivets, have a mandrel and can be installed from one side with a rivet gun. Common materials include steel, aluminum, stainless steel, copper, and titanium. Head shapes include round, countersunk, and structural heads, with finishes that provide corrosion resistance. Installation generally involves drilling or punching a precise hole, inserting the rivet, and deforming the tail to lock the pieces together.

Rivetti are widely used in aerospace, automotive, construction, electronics enclosures, and general metal fabrication. They offer permanent joints with good shear strength and resistance to vibration, and they can be lighter and easier to install in certain contexts compared to threaded fasteners. Limitations include the need for proper hole preparation, limited removable joints (especially solid rivets), and the potential for work-hardening or material damage if not installed correctly.

Rivetti is also an Italian surname. As a family name, it appears in various countries, associated with individuals across diverse professional fields.
