Rivet nut
Riveting means that during the riveting process, part of the material of the riveted screw or nut is plastically deformed under the action of external force, and the base material
The material forms a tight fit to achieve a reliable connection of the two parts. The commonly used ZRS and the like are connected to the substrate by using such a riveted type. The riveting process is relatively simple, and the joint strength is low, and is usually used to limit the height of the fastener and to withstand a small torque.
