Rivet nuts (also know as rivnuts, blind nuts or nut-serts) are internally threaded inserts, used in applications with small material (wall) thickness. They create a strong thread in thin sheets of material for high strength fastening from bolts and other threaded articles.
They are easy-to-install, reliable fasteners that can provide a strong load-bearing thread into thin materials.
