Rivet Nut Studs: Composed of two pieces, rivet nut studs contain the rivet nut and an externally threaded stud. In these types of nuts, there is room for the internal thread to be positioned at differing angles, allowing for flexible bolt installation. Slotted rivet nuts offer an extensive grip range ideal for fastening varying thickness materials.įloating Rivet Nuts: Floating rivet nuts allow for flexible fastening of workpieces. These often come pre-bulbed for a secure grip and easier installation. Slotted Rivet Nuts: Slotted rivet nuts come with slots cut into the shank of the rivet nut body. Hexagonal rivet nuts have hexagonal shaped shanks and are usually designed for more load bearing applications. Hexagonal Rivet Nuts: Hexagonal (hex) rivet nuts, like round ones, provide great spinout resistance and are used for hexagonal shaped holes. Closed-ended rivet nuts provide a barrier for liquid or particles entering the blind side of the installation material. Round rivet nuts can be made either with open or closed ends. Knurled surfaces provide greater spin-out resistance by gripping the installation material. Round Rivet Nuts: These nuts are made for circular holes and have a smooth or knurled surface on the shank of the nut. Rivet nut installation can even be automated through 6-axis robots or other automotive processes. While weight reduction and load-bearing are certainly advantages of using rivet nuts, manufacturers can also benefit from reduced costs due to faster assembly. This makes them also great for use in furniture, certain consumer goods, and electronics. Additionally, rivet nuts can have high shear and tensile strengths, making them ideal for load bearing applications. While the rivet nut will be permanently fixed to the material it is attached to, materials assembled to the rivet nut via a bolt, pin, or other devices can be removed.īecause of their light weight, small size, and easy installation, they are often used in applications where weight reduction is critical (i.e. Like a normal rivet, rivet nuts are blind – as in, only one side of the workpiece is visible when installing the rivet nut. Rivet nuts can be used to fasten a variety of materials together – including different types of metals, plastics, fiberglass, and carbon fiber. This makes rivet nuts one of the most versatile fastening devices that exist.ĭrill pilot hole Install with rivet gun Insert threaded hardware When are Rivet Nuts Used? 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. Finding the right fastener for a project requires more thought and deliberation than you would expect.
