Rivet nuts are generally used for thin-walled plates and are embedded by pressure. The contact surface is contact stress, that is to say, the strength depends on the connector and the parent body. The nut is subjected to shear stress, so if the strength of the nut is not enough, it will be shared. If the strength of the matrix is not enough, it will be plastically crushed and deformed to fail.
