A rivet is a mechanical fastener designed to join two or more objects together by being inserted through holes in the material and then permanently deformed to create a solid connection. These fasteners, typically made of various metals, function by transferring load across the joint material, resisting tensile and shear forces. Their installation involves passing a core material through aligned holes in mating components and then applying force to the exposed ends, causing the material to deform and lock the joint into place. Riveting is widely used in structural engineering, aviation, and construction for connecting structural elements, providing robust, high-load capacity joints in various engineering applications.
