In a previous post, we discussed many of the different types of standard fastening nuts. In this edition, we’ll talk about locknuts. The major difference between standard nuts and locknuts is standard nuts consist simply of a threaded hole, while locknuts are designed to prevent loosening when exposed to vibration. As with standard nuts, there are many different variations of locknuts from which to choose. We’ll take a look at some of the more popular locknuts here.
The current challenges for Fire Truck and other specialty vehicle manufacturers are complex and ever-changing. Challenges include supply chain volatility, rapid design changes to accommodate electrification, and new ways of differentiating between manufacturers.
Supply Chain Simplification:
Using adhesives, such as Plexus®, can help simplify supply chain troubles because a suitable structural adhesive can replace multiple SKUs of different fasteners. As a result, Plexus adhesives dramatically reduces the risk of line-down situations due to specialty fastener stock-outs. In addition, SKU reduction by replacing with one structural adhesive can lead to significant inventory cost savings.
Even if you’re not ready to eschew fasteners altogether, applying Plexus adhesives along with mechanical fasteners at the ends can still help simplify the supply chain. This style of manufacturing leads to very fast throughput and “one-piece flow.”
The speed and ease of installation of blind fasteners make them an excellent choice for manufacturers of all types of products. This is especially true when access to an application's backside is limited at best or completely inaccessible.
Once determined that a blind fastener is right for the application, the user then must decide which type of blind fastener is most appropriate. While many factors could play into this decision, strength requirements and vibration resistance are two criteria that sit at the forefront.
For lighter duty applications that are not load-bearing (under 100 lbs. of shear and tensile strength), a standard blind rivet is often adequate. For more information on standard blind rivets, check out our four-part series on blind rivets.

This is Part 4 of a 4-part series on Blind Rivets
In the first three parts of our series on blind rivets, we discussed the history of blind rivets; the most important factors to maximize joint integrity (grip range, hole size, material, and installation tooling); rivet selection (material, diameter, grip range, head style), and the most common types of blind rivets (drive-pin and break-stem; open-end, closed-end, self-plugging). To review any of those posts, please click on any of these links.
In this final installation, we’ll break down some other variations of blind rivets. There are many different styles of blind rivets for specific applications, including different types of structural blind rivets.
Structural blind rivets are required for applications requiring higher load and vibration tolerances. They have higher shear and pull-out strength than standard blind rivets. Many offer a wide grip range, while most have exceptional clamping force. While they’re not quite a replacement for a blind bolt, such as the Huck BOM, or heavy hex bolt, they are a great option when a standard blind rivet just won’t suffice.

This is Part 3 of a 4-part series on Blind Rivets
In part one of our series on blind rivets, we briefly looked at their history and discussed the two most important considerations to maximize joint integrity: Grip Range and Hole Size. In part two, we broke down the importance of material and tooling as they pertain to joint integrity, as well as the specifics of blind rivet selection. If you have not yet read either of those posts, click HERE for part one and HERE for part two.
In this post, we'll talk about the most common rivet types and their functional differences.
There are two common blind rivet types: Drive-Pin and Break-Stem.
Drive-pin blind rivets have a partial hole in the body and a mating pin that protrudes, positioned in the hole. The installer hammers the pin into the rivet body so that it's flush with the top of the rivet head. One of the significant benefits of a drive-pin rivet is that no special tools are required for installation. You can literally use a hammer if you wish. Drive-pin rivets can also be used with almost any material and don't require a hole to be drilled all the way through to insert. A drive-pin rivet's disadvantage relative to other types of blind rivets is that a backing block may be needed for installation depending on the material and application, which mitigates the benefit of blind installation. They also offer less clamping force than most other rivet styles.
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.
