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

  • The body of cylindrical shape called rod, stem or spike.
  • check
    Head in the shape of a spherical cap and whose diameter is greater than the body of the rivet.

Types of Rivets

  • Compression rivets.
  • check
    Blind rivets that can be: with the stretching mandrel, with a guided pin, threaded and those that are chemically expanded.
  • check
    Rivets of the blow which uses a hammer for its installation.

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.

Pop Rivet

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

  • The resistance achievable with a rivet is lower than that which can be achieved with a screw.
  • check
    The joint is not removable, which makes maintenance difficult. Beyond this, removing it is simple (you must use a perforator or drill with a wick or high-speed steel drill bit, whose outer diameter must be equal to that of the rivet), although once we remove it, we must use a new rivet.
  • check
    It is not suitable for very thick parts.
  • check
    This accessory is not reusable like the screw. It is only used once.

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.
