This is Part 2 of a 4-part series on Blind Rivets
In part one of our series on blind rivets, we briefly looked at the history of the blind (a.k.a. pop) rivet and discussed the two most important considerations to maximize joint integrity when using them: Grip Range and Hole Size. If you have not yet read that post, click HERE.
We'll now break down the third and fourth most important aspects to consider to maximize joint integrity using blind rivets: Material and Installation Tooling.
- Material - A good rule of thumb when selecting a blind rivet is to use the same material rivet as the substrate into which it's being installed. If you're riveting sheets of steel together, use a steel rivet. The same goes for aluminum and stainless steel. This is important because using dissimilar metals may result in galvanic corrosion, depending on the application's environment.
Installation Tooling - What role exactly does installation tooling play in how a blind rivet works? It's simple. An installation tool has one job … to pull the stem of the blind rivet up through the rivet body until the pull force of the tool overcomes the tensile strength of the rivet stem, resulting in the stem breaking off at its predetermined breakpoint.
There's nothing more to it than that. All strength parameters and application criteria of a properly installed blind rivet reside within the rivet itself. If the installation tool breaks off the blind rivet stem, it's done its job. So, this means that the primary consideration for blind rivet installation tooling is accessibility. Can the tool fit into the area around where the rivet needs to go? Fortunately, there are many different configurations and types of tooling available. So, in most cases, you'll find an installation tool that quite literally "fits" your needs.
