![]() Because it’s considered a blind fastener, rivet nuts are used in applications where only a single side of the workpiece is accessible. Rivet nuts can have round, square, splined, or hexagonal bodies. Rivet nuts are derived from standard rivets and are paired with standard sized bolts. Originally used to secure deicing boots to aircraft wings, rivet nuts have since been adapted into many different forms and types for various fastening applications. Also called blind rivet nuts or threaded inserts, rivet nuts are internally threaded components that are completely anchored on one side. Rivet nuts, alternatively known as RIVNUTs®, were developed by the BF Goodrich Company in the late 1930s. ![]() In this article, we dive deeper into rivet nuts and discuss everything there is to know about them – from what they are and how they’re used to different types of rivet nuts and their advantages. From use in aerospace and automotive manufacturing to furniture and consumer goods, rivet nuts are an innovative and easy fastening method that’s both revolutionized and simplified how products are assembled. Finding the right fastener can seem impossible, especially when trying to fasten thin or brittle materials together. If you’re looking for a fastener that provides fast installation at minimal cost a rivet nut is the ideal solution and can easily be installed by air rivet nut tooling or hand tooling.Finding the right fastener for a project requires more thought and deliberation than you would expect. In your vehicle, there are likely dozens of rivet nuts for all of the reasons stated above. It is used in a wide array of applications in the automotive, heavy truck, and manufacturing industries as they move toward making their products both lightweight and easier to make. The rivet nut itself can be installed into a variety of a different materials including metal, plastic, fiberglass and carbon fiber. Once the rivet nut is installed, fasten your material through the rivet nut with any compatible externally threaded fastener and you’re all set. No need to struggle to reach around the back of the bolt to fasten the material with a nut. Meaning, these fasteners can be installed securely from one side of the work piece. Closed end type rivet nuts are ideal if you’re looking for a sealed end rivet nut, providing an effective option for the ingress of water.Ī main strength of rivet nuts are that, just like with traditional rivets, they are blind. Rivet nuts also come in two variations of end style – either open ended where the bolt can protrude through the rivet nut without obstruction, or a closed end type. ![]() These must be installed into a hex hole which are cut into the substrate for installation. Half hex and full hex rivet nut bodies are also available offering high performance with the ability to resist turning. However, when set correctly plain bodied rivet nuts offer no degradation in performance over serrated bodied rivet nuts. Serrated bodies are ideal for smaller sized rivet nuts in thin sheet materials where the serrations help to grip more firmly in softer materials such as aluminum. These are found in either plain or serrated style. Reduced head style rivet nuts offer a minimal protrusion of the rivet nut head from the installation material whilst a countersunk head style can be used if you’re looking for a completely flush finish.īody styles vary for rivet nuts, with round body rivet nuts being most common. ![]() However, countersunk head and reduced head styles are also widely available. These provide a reliable anchoring point for almost all applications. Rivet nuts come in a wide selection of head and body styles with flat head style being the most popular in use. ![]()
