💡 How do threaded rivet nuts help when joining thin metal sheets? Threaded rivet nuts create strong anchor points in sheet metal without welding. - They let you add bolts or screws into pipes and panels that are too thin for regular nuts. - Install them from one side only in auto body panels or metal frames. - Swap sizes fast when the job moves between M3 and M12 fasteners. - Keep a set on hand for quick fixes in the shop or on site.
