Anyone who has ever had to install rivets or blind fasteners understands how time-consuming it can be to have to load the mandrel one fastener at a time. Precision fastener installation takes attention, and it can be tedious work, especially if you are using the same type of fasteners on a large job, such as assembly work or on a production line. Fortunately, there are Speed Fastening systems to simplify the task.

As the name implies, speed fasteners are designed to provide easy and fast installation of blind fasteners. The concept is simple: Rather than manually loading the mandrel for each fastener, Speed Fastening systems have the fasteners already loaded onto a longer mandrel, so after each fastener is set, the next one is immediately ready to go. The result is a substantial savings in production time and costs.

Speed Fastening systems are ideal for applications in which the same fastener type is applied throughout the job, such as in manufacturing or assembly work. The same fasteners are stacked on the mandrel, so all you have to do is place and pull. This approach not only reduces installation time but also promotes consistency and reduces rework and inspection time.

Stanley Engineered Fastening is the leader in the market with its Avdel line of speed fasteners. Avdel engineers estimate that speed fasteners can cut installation cycle time to less than two seconds. In fact, if you are efficient, you can install as many as 60 speed fasteners per minute. This makes Speed Fastening systems efficient for small as well as large jobs. If you are installing more than 10 breakstem fasteners at once, then speed fasteners are sure to save you time and money.

Chapter 1

The Birth of Speed Fastener Systems

Speed fasteners were originally developed for airplane manufacturing in the 1930s by French engineer Jacques Chobert, the creator of the blind rivet.

Chobert originally developed the blind rivet to make manufacturing more efficient, so rivets could be installed from one side of the material and by one person rather than two. Chobert’s system called for rivets to be loaded onto a mandrel and placed in a pre-drilled hole. Once the rivet was inserted in the hole, the mandrel would pull the blind side of the rivet, drawing the two pieces of material together and forming a bulb on the blind side for a strong, lasting joint.

Chobert’s blind fasteners were revolutionary, but they still required rivets to be manually loaded and set one at a time. Breakstem rivets also required that the stem of the fasteners be broken off once each set was complete, which meant 60 percent of the fastener material was wasted and had to be collected. Chobert was determined to make his fastener system more efficient and less wasteful.

By creating a longer mandrel and using precision fasteners cut to size, Chobert created a way to install fasteners faster and without waste. Loading the longer mandrel with multiple fasteners made it possible to improve the placement cadence, making it simpler to install one rivet after another. This led to the creation of the first magazine-fed fastener system.

Today, speed fastener systems either use bowl systems that hold hundreds of fasteners to feed the riveting tool or they use prepackaged rivets arranged in preloaded paper magazines. These paper magazines slide onto the mandrel, and when you peel the paper away, the mandrel is loaded and ready to go. Speed fasteners also eliminate wasted metal and the need to pick up breakstem pieces.

Bringing Efficiency to Many Applications

Having proven their value in aviation manufacturing, speed fastener systems have become widely used in a variety of applications—anywhere repetitive, precise fastener installation is required.

For example, just as speed fastener systems can be used to make airplanes, they can be used for other light metal assembly applications, such as truck trailers, rail cars, and the like.

The assembly line is one area where speed fasteners have increased efficiency. In automotive manufacturing, for example, speed fasteners dramatically speed up production. The same can be said for many types of manufacturing, from hot tub construction to boat building.

Speed fasteners also are widely used in electronic sub assembly. Specialty fasteners made from brass and aluminum are ideal for attaching circuit boards. Fasteners can be used to hold subassemblies in place, and even installed as standoff pillars for printed circuit boards (PCBs) using rivets with a threaded bore.

You also will find blind fasteners used in manufacturing lighting systems and household goods. These assemblies are likely produced using speed fastener systems.

Any application in which speed and efficiency are important will benefit from speed fastener systems. Specialty tools and mandrel types can be found for any application, and specialty rivets and fasteners are available in virtually any material, length, diameter, and finish.

Selecting the Right Speed Fastener

To get the maximum benefit from any speed fastener system, you have to choose the right components for the job.

That means choosing the right combination of fasteners, mandrels, nose equipment, and tools for the job. You also want to make sure you use the correct fastener material. Fasteners are available in steel, stainless steel, aluminum, and brass, with domed, low-profile, and countersunk heads.

When selecting the right speed fastener system, you have other considerations as well. For example, does the fastener need to be removed, or is a threaded standoff pillar required? Is a high clamp or wide grip required? Do you need a wide head or controlled clamp pressure for softer materials? These are just a few criteria to consider when choosing the right speed fastener system.

Installation and Installation Tools

In addition to selecting the right kind of fastener, you need to choose the right installation approach, including the right tools.

You want to scale the installation system to the required task in order to optimize installation, maximize fastener performance, and promote cost-effective production.

Matching the right installation tools to the application ensures smooth, trouble-free installations. If you consider the installation equipment an integral part of the speed fastener system, you can be sure to have smoother production. Matching the right installation equipment to the job and to the fastener has a number of benefits:

  • It ensures a reliable fastener feed, which delivers higher speed.

  • You can cut assembly cycle times to one or two seconds.

  • Fast magazine reload times shorten production time even more.

  • It simplifies single-side assembly.

  • Matching the right tools to the fastener minimizes maintenance costs.

  • You can scale production to meet your needs, from low-volume batches to automated assembly lines.

There are three basic approaches to speed fastener installation. Each type of tooling is designed to accommodate different production levels and fastener volumes.
