![]() With universal head rivets have been specially designed for the aircraft as a replacement for conventional rivets with round head, and rivets with a low semicircular head ("brazier head").įigure 1 - The head of US aluminum rivets The solid rivet may have various shapes of heads, however, so-called universal head and the countersunk head with a cone 100 ° are the most common, at least, in American aircraft designs. This forms a second head rivet, which firmly holds together the materials to be joined. As a result of these actions the rivet shank expands to a diameter approximately one and a half times larger than the original. After that, as a rivet installed in this pre-drilled hole, the rear end face down or deform one of several ways, by riveting hammer manual to pneumatic tools riveted. To connect together two or more metal sheets, a rivet is placed in the hole diameter slightly larger, than the diameter of the rivet. SUMMARY rivet like fastenersīefore installation of the rivet consists of a smooth cylindrical rod with factory head at one end. Since the rivets are put "on continuously", the order, to take them off their drill, which it is quite a difficult task. Linked connections are in principle not sealed, if not riveting to use special sealants or gaskets. The greater the total thickness of the joined sheets, the more difficult it is good to combine them with rivets. The thing is, rivets that tensile strength is usually very low in comparison to their shear strength. Rivets are designed to work on a cut, however they are not used for joining thick materials or abraded material if subjected to tensile loads. Moreover, for setting the rivets can be used automated high-performance tools and equipment. ![]() The advantages of the rivets are relatively low cost, and less complexity compared to screws and nuts. ![]() They are also widely used and the construction and repair of small river and sea vessels, such as motor boats and aluminum boats. These rivets are the oldest and the most reliable of all types of fasteners. Rivet with a solid core - rivets under the hammer - are a common type of rivets, which are used in aircraft structures. For beginners it will be helpful for the first acquaintance with aluminum rivets, experts-professionals can be compared with the American practice of domestic, including, the repair aluminum boats and boats. Below are excerpts from a practical guide for the American aviation mechanics for use aluminum rivets in the repair of aircraft.
