A rivet is one of the oldest types of fasteners. Even more than 2500 years ago, they were used in the manufacture of military armor in Greece, Macedonia. Of course, ancient rivets bear little resemblance to modern fasteners, but the principle of operation is the same.
The next stage in history, where the active use of the rivet was noted, was the century of the industrial revolution of the late 19th and early 20th centuries. The creation of steam engines, steel bridges and other building structures used this type of fastener everywhere. At this stage the rivet had a steel core and a semicircular head. During installation, the end of the rod was riveted, thus creating an integral connection.
In this classic form, the rivet has been used for a long time, and in some places it is still used today. But progress does not stand still, so engineers constantly made attempts to improve the design. The improvement concerned primarily the simplification of the installation method, because special technical devices are required to rivet the rod of a classic rivet. In addition, this method of installation requires a two-sided approach to the fastener.
As a result, a new type was born — a blind rivet. Its installation requires only a one-sided approach, and it does not require significant efforts to fix it. You can install the blind rivet manually using a simple tool — a riveter.
The design of a single-sided blind rivet consists of two parts. The first part is the rivet body itself, which includes the head and the tubular rod. The second part is the rod that is inserted into the body. At one end of the rod there is an extension that abuts against the end of the tubular part. During installation, the rod is pulled out and crushes the tubular part, which, expanding, fixes the rivet.
Due to the ease of installation, now this type of rivet has almost replaced the classic design. The main rule in the selection of a modern design is the correspondence of its length to the thickness of the parts to be fixed. The principle the longer the better does not work here. After all, the thickening can form before the fixed plane. In addition, it is necessary to monitor the uniformity of the materials of the rivet and the parts in which it is installed. This rule is quite important, since galvanic corrosion can lead to a loss of strength of the connection or even its complete destruction.
The modern design also has high decorative qualities. Painted to match the color of the base material, it becomes almost invisible.
You can buy rivets today at any construction market or in a construction hypermarket. But, for wholesale deliveries, it is better to choose reliable large dealers that represent manufacturing plants, we advise you to visit this site — http://www.rusbolt.ru/catalog/290/.
