Rivet Nuts, Steel, M5 x 0.8, 3.30-5.70 give you strong, reusable threads in thin or soft materials where a regular tapped hole won’t work. Made from durable steel, they expand to form a solid anchor once installed, creating a reliable base for screws and bolts. Perfect for mounting panels, attaching hardware, or fastening components cleanly, rivet nuts make repeated assembly easy without damaging the material. A simple, sturdy solution for everyday fastening jobs.
