General Idea About the Rivet nut

Speaking of fasteners, bolts, nuts and screws are most common in our daily life. There are many other ways in which the fastening rivet nut. The development of non welding technology and bolted joints, a long time ago, riveting is popular, in the metal structure building and structure as the Eiffel Tower construction is necessary, as well as in the fields of automobile and airplane.

In general, a stainless steel rivet nut is composed of one end of a cylindrical shaft smooth and a head called the factory head. And the other end of the head, tail or head shop called a buck. In order to be held in place by the rivets, 1.5 times the diameter of the shaft. They used a hammer to help install such things. In this process, the need to promote the factory head is inserted into the rivet insertion hole stress. This is true, often fill tight rivet nut. As a result, it is difficult or impossible to obtain work closely with other fasteners etc..

Of course, according to the size of holes, the two rivet diameter and length variation range is wide, to be sure, there are many different specifications for rivet nuts. Mainly includes the solid rivet, semi tubular rivets, rivet, rivet, drive, flat head rivet, rivet self piercing rivets and friction lock.

Solid rivet fasteners are one of the oldest and most reliable type. It is provided with a hammer head is inserted into the shaft like ordinary deformation. Structures are widely used in aircraft. According to statistics, hundreds of thousands of solid rivets used in the framework of modern aircraft assembly, to make it more safe and reliable. They are usually made of aluminum alloy, titanium, nickel based alloys and design of circular (general) or 100 degrees countersunk head. In addition, the steel rivets are mostly adopted the static structures such as bridges, cranes, and architectural framework.
