Blind Threaded Rivnut Fasteners

When you need to add a load-bearing thread to a thin-walled pipe or a sheet metal panel where you cannot reach the back, our Blind Threaded Rivnut Fasteners are the perfect hybrid solution. They function like a pop rivet but leave behind a clean internal thread. By using a pull-tool, the body of the rivnut collapses and expands against the hidden side of the hole, locking it permanently. We have been the leading supplier of these fasteners in Shanghai since 2006.

Our Blind Threaded Rivnut Fasteners are tested for extreme performance. An M6 stainless steel rivnut installed in a 1.5mm plate withstands an axial failure load of ≥3.5kN and a torque-out of over 10N·m. We design our "deformation zone" to be uniform, ensuring the nut expands evenly to grip the plate without spinning. With a re-usability rating of over 20 bolt cycles, our Blind Threaded Rivnut Fasteners are far superior to simple sheet metal screws for long-term reliability.
