The Principle Of Countersunk Head Rivet Nut

The countersunk head rivet nut is also called a rivet nut, a self-fastening nut, which is a kind of nut used on thin plates or sheet metal. It has a round shape and has embossed teeth and guide grooves at one end. The principle of countersunk head rivet nut is to press the embossing teeth into the preset holes of the sheet metal. Generally speaking, the aperture of the preset holes is slightly smaller than the embossing teeth of the rivet nut, and the flower teeth of the rivet nut are squeezed into the plate by pressure. The periphery of the hole is plastically deformed, and the deformed object is squeezed into the guide groove, thereby producing a locking effect.

The countersunk head rivet nut is also divided into smooth surfaces and vertical patterns. It is riveted into a thin plate with chamfered. After installation, its head surface is parallel to the surface of the thin plate. The available materials are: galvanized iron, 304 stainless steel, 316 stainless steel Blind rivet nuts, the national standard number is: GB/T17880.2.

And there are many types of blind rivet nut subdivided.
