Blind rivet nuts --- also known as rivnuts and blind nuts, can be easily installed into sheet metal as well as tubing and extrusions in steel, stainless steel, aluminium and a variety of plastics.

They are available in body styles of round, knurled and hexagonal with head styles of flange, countersunk and reduced in aluminium, steel and stainless steel in sizes M3 to M10 with grip ranges of 0.5 to 6mm. Invented in the United States in the 1930s for the aerospace industry, applications now include medical, marine, automotive, aerospace, white goods, telecoms, electronics and general engineering.

Blind rivet nuts provide many benefits including a stable thread on thin-walled components, simple blind (one-sided) installation, fast assembly time, low assembly costs (easy installation with 1 single operation of the hand), low installation costs (no expensive setting tools needed), working in close-to-edge applications and no damage to painted or finished surfaces. They can be set with a hand or pneumatic tool, a press or an automatic installation unit. They can be also used to clinch separate sheets together (acting as a rivet) allowing assembly of another component with a bolt or screw.
