Types and Uses of Rivets
The rivet, also known as rivet pop, is a fastening element whose function is, like the screw, to join two pieces permanently.
It is a mechanical seal made up of a cylindrical tube with a head at the bottom whose diameter is larger than the rest of the rivet so that when you insert it in a hole, it can fit together, to join two different pieces, whether or not they have the same material.
Nowadays, its use is of vital importance as an assembly technique due, in part, to the development of automation techniques that make the joining process cheaper.
Parts of a Rivet
Types of Rivets
The rivet or rivet is used to join two or more pieces fixedly and permanently, including different materials. The fields in which riveting is most commonly used as a fixing method are automotive, household appliances, furniture, hardware, military industry, laminated metals, etc.
How Is a Rivet Used?
To place the rivets, first a hole is drilled or a perforator or also known as a drill, which is a device that is used to make a hole, and then the cylindrical body must be inserted into the hole. It must have the right dimensions so that it protrudes, then deforming the protruding part to form a new head.
Sometimes, rivets are placed cold for diameters of eight millimeters; and hot for diameters greater than ten millimeters. The right tool for riveting is the riveting machine.
If you wish to use a method for joining one or more pieces, whether or not it is made of the same material, we present the advantages that riveting has over other fastening elements such as screws or nails.
It is considered to be a cheap and automatable method of joining.
It is useful for the union of different materials as well as for two or more pieces.
There is a great variety of models and materials of rivets, which allows more aesthetic finishes that with the screwed unions.
It allows blind joints, i.e., the joint when only the external face of one of the parts is accessible.
Recommendations When Using a Rivet
We must take into account that when we want to join two surfaces, and we are going to acquire the necessary rivets, we must consider the thickness of both surfaces. These surfaces also depend on the thickness, the head of the rivet must be longer, the diameter of the hole, and the materials to combine. Whether softer rivets should be used or not, it all depends on the type of the material.
