A rivet is a special type of metal fastener. It is manufactured to the German national standard DIN 662, which is equivalent to GOST 10301 and complies with the international standard ISO 1051. Unlike bolts, screws, nuts, washers and spring lock washers, which are removable fasteners, a rivet is not: once installed, it cannot be reused.
Despite this, rivets are widely used in aviation, in the manufacture of small vessels, in bridge construction, and in various structural elements. In the early last century, the hulls of civilian and military ships were assembled precisely with rivets.
Two joined surfaces tend to separate from the fastener: tensile forces arise, directed at pulling the parts apart, as well as shear forces. In the first case, the fastener experiences normal resistance; in the second, shear resistance.
There are many cases where forces acting on the joined surfaces tend to destroy the structure through shear, that is, shearing forces. Under such conditions, a rivet is the optimal fastening element. Today rivets are gradually being replaced by welding, but they continue to be used, for example, when joining rafters, steel sheets in boilers, and large tanks.
A rivet is installed as follows: holes are drilled in the two surfaces to be joined, with a diameter matching the thickness of the rivet shank. A heated shank with a head is inserted into the holes, after which the other end is hammered flat using a special hammer or riveting machine.
