💡 What is a rivet nut insert kit used for in metal fabrication and how does it work? A rivet nut insert kit lets you install threaded nuts into thin metal without welding, creating strong, load-bearing anchors that stay flush with the surface. This approach is handy for on-site repairs and prototyping. - Handy for attaching panels, control boxes, or furniture frames where a threaded hole is needed after assembly - Works with standard rivet nut tools to collapse and form a secure backside flange - Supports metric sizes like M3, M4, M5, M6 in a single kit
