Rivet nuts, rivet nuts, rivet nut American, American Thread rivet nut
Standard: GB / T17880.1
Also known as riveting nut, pull the cap, and instantly pull cap, for fastening the field of all kinds of metal plates, pipes and other manufacturing industries, it is now widely used on sheet metal / thin sheet / chassis cabinets. To solve the sheet metal, thin tube fusible weld nut, internal tapping and other shortcomings easy to slip teeth develop. Left for flat head rivet nut.
Rivet nut features: If a nut products to be installed on the outside, but inside the space is small, and can not by pressure riveting / rose riveting or otherwise fail when its strength requirements, you can use riveting applicable to all. The thickness of the sheet, pipe 0.5MM-6MM) pneumatic or manual fastening areas riveters at once riveting solid, convenient and secure, replace traditional welding or press-fit technology advantages relative to other processes: stronger than the rivet nuts and more convenient (no pads) than weld nuts.
Rivet nut species There are many commonly used flat head / countersunk head / small countersunk head / hex head rivet nut / hexagonal rivet nuts and blind pass over each type.
Under flat head rivet nut and its technical parameters, the cylinder rod end and column lines are divided into two, after staking its head exposed to a thin sheet, the column lines can play the role of non-slip, flat head rivet nut is a rivet nut The most common one is the most secure
