Riveting is the process of joining materials with a rivet, a permanent mechanical fastener that starts as a smooth cylindrical shaft with a head on one end and an end called the tail on the other. To install a rivet, the tail is inserted through a hole in the parts being joined and then flattened with tools into a shape resembling the original head, called the shop head or buck-tail, so the finished fastener effectively carries a head on each end. This lets a riveted joint support tension loads, but it is markedly better suited to carrying shear loads, those applied perpendicular to the shaft, which is why riveting has long been favored for structural assembly such as aircraft skins, where sheets must resist forces acting across the joint rather than along it.

Origin YearRivet holes appear in Egyptian spearheads of the Naqada culture dated between 4400 and 3000 BC, and riveted Bronze Age sword and dagger hilts are also attested; no single point of origin is established within that range. Core PrincipleA rivet is installed by inserting its tail, a smooth cylindrical shaft opposite the manufactured head, through aligned holes in the parts being joined, then flattening the tail into a second head so the fastener grips both parts permanently and carries shear loads across the joint far better than tension loads. 1 FAQs
What is a blind rivet and when is it used?
A blind rivet is a hollow-bodied rivet with a mandrel that lets it be set from one side of the work.
A blind rivet is a two-piece fastener made of a headed, hollow rivet body and a solid mandrel. It is used when the back of the workpiece cannot be reached, because it can be set from one side of the work. The setting tool pulls the mandrel through the body, which expands the body and forms the joint, and at a predetermined setting force the mandrel breaks and falls away.
