Rivet nut, also known as a threaded insert or nutsert, is a hollow, internally threaded fastener designed to be installed into thin materials where a tapped thread is not possible. Once inserted using a rivet nut tool, it provides a strong, permanent thread for bolts or screws. Rivet nuts are widely used in automotive, aerospace, electronics, and machinery applications, offering reliable fastening in sheet metal, plastic, and composite materials. Available in steel, stainless steel, aluminum, and with various surface finishes for corrosion resistance.
