Rivets are used to join two or more parts together permanently. There are a few different types of rivets but all of them use a tail, which is a smooth cylindrical shaft, that gets placed in a hole to grip the two parts together. It is important to know what grip range you require. The grip is the total thickness of the two materials being joined together. Rivets are known for their reliability and durability which is why they are commonly used in construction, aviation and automotive.
Types of Rivets
Solid Rivets – Solid rivets are the most common type of rivet and are used in a variety of applications. They are made of a solid piece of metal and are inserted into a pre-drilled hole. They are then hammered or pressed down until the end of the rivet is flush with the surface of the material being fastened.
Blind Rivets – Blind rivets are used when the back of the material being fastened is not accessible. They consist of a mandrel, which is pulled through the body of the rivet, causing it to expand and fasten the two materials together. This type of rivet requires a specialized tool for installation.
Tubular Rivets – Tubular rivets are hollow and have a head at one end and a tail at the other. They are used in applications where the materials being fastened are soft and cannot withstand the pressure of solid rivets.
Drive Rivets – Drive rivets are similar to solid rivets, but they have a smaller head and are driven into place using a hammer or drill. They are commonly used in automotive and construction applications.
Industry Applications of Rivets
Construction – Rivets are commonly used in the construction industry to fasten steel and other metal structures together.
Automotive – Rivets are used in the automotive industry to fasten body panels, chassis components, and other parts together.
Aviation – Rivets are used in the aviation industry to fasten the skin of aircraft to the frame, as well as other components.
Marine – Rivets are used in the marine industry to fasten boat hulls and other components together.
The specific needs of the project will determine which material should be used. You must factor in the strength, corrosion resistance, conductivity, weight and of course, cost. The most common materials for rivets are steel or aluminum. Some rivets have different materials for the body and mandrel. For example, a blind rivet may have a steel mandrel with an aluminum body. The material options for rivets are listed below. Please note certain types of rivets may only be available in specific materials.
Overall, rivets are a reliable and durable type of fastener that are used in many applications across a variety of industries. Each type of rivet has a unique design, material, and use. Whether you are in the construction, automotive, aviation, or marine industry, rivets are an essential component for fastening materials together permanently.
