After reading Why Rivet Nuts?, you may come away with, well that’s good, but what’s a rivet nut stud?

Rivet nut studs are simply rivet nuts with an already outward protruding stud installed in the rivet nut. Instead of threading the bolt into the rivet nut, you thread your attachment on to the bolt and you would attach a nut to tighten down the attachment.

They work the same way as a blind rivet nut, are installed in a similar way, and already have the stud installed. This saves installers the step of putting in the through bolt. Also, when putting an assembly together, it can be beneficial to have something that gets hung on the stud before getting tightened down. This gives the operator something to take the weight off the component before installing the nut over the stud.

Like most blind rivet nuts, rivet nut studs are great replacements for weld nuts when you need a blindly installed, outward-protruding stud for your joint. They are also only needed to be installed in one side of the work piece, where access to the backside is not possible.

Rivet nut studs can come in a variety of sizes and shapes. Round body, hex body, wedge head, knurls – anything a typical rivet nut can be made into and rivet nut stud can. Rivet nut studs are very customizable. Another thing to consider is the stud. How much thread or stud length will you need for the application? Rivet nut studs can be made to a specific length for the application.

The performance of rivet nut studs vs. a typical rivet nut is very similar, although harder material like steel might yield better performance results than softer material. In general, the performance of spin-out or pull-through of a rivet nut stud compared to a typical rivet nut is negligible if all things are equal.

Rivet Nut Stud Application Use

There are a number of different applications a rivet nut could be used for:

  • Wire harnessing on a Truck Frame
  • Any applications where a rivet nut stud will be used as a hanging point on a centering pin
  • Locating or guide pin
  • Can replace any weld nut application
  • Automotive applications, like spoiler installations, installed into castings, roof racks
  • Agriculture applications
  • Heavy Truck applications

Rivet nut studs are typically more expensive than a rivet nuts, but remember, the cost of the stud or bolt is also considered into the higher price. When you factor a rivet nut plus a bolt/stud, it’s roughly the same amount per part ($rivet nut stud = $rivet nut + $stud/bolt). Another thing to consider is the potential in time saving, or even ease of assembly for assemblers and installers. Rivet nut studs could very well be a more productive fastener depending on the application, saving money by being able to assemble more products faster.

Rivet nut studs are a great option and should be considered any time you have an application that needs a rivet nut and weigh out the options if it makes sense to use one.
