Blind threaded fasteners and tools designed for the

assembly of sheet metals, tubular structures and plastics





Rivnut®, the original blind-installed tubular rivet with internal threads, has been solving installation and fastening problems for over 80 years. A Rivnut® fastener is a tubular rivet with internal threads. It can be installed into dissimilar materials and has internal rolled threads for thread strength.
