Rivet Nut Types

A User's Guide to the Various Rivet Nut Options Rivet nuts, also known as nutserts or rivnuts, are a type of fastener that combines the functions of a rivet and a nut. Essentially, they are threaded inserts designed to be installed into thin materials like sheet metal, plastics, and fiberglass. This makes them ideal for applications where using a standalone bolt and nut might distort or damage the material due to clamping pressure. Commonly used in industries such as tubular furniture, switchboards, kitchen appliances, refrigeration units, air conditioning systems, and metal cabinets, rivet nuts are primarily available in steel, stainless steel, or aluminum. They feature a hollow threaded body to house a mating fastener. Installation is straightforward using a nutsert tool, which compresses the rivet nut into the material, creating a secure blind-side flange that holds the nut firmly in place with a permanent thread. Rivet nuts come in various metric sizes—M3, M4, M5, M6, M8, M10, and M12—as well as some selected imperial sizes, such as 3/16", 1/4", 5/16", and 3/8". These dimensions refer to the internal thread size and not the body diameter. One of their key advantages, much like pop rivets, is their ability to be installed from one side of the workpiece. This eliminates the need to struggle with accessing the backside of the bolt during installation. Once installed, rivet nuts allow you to use any compatible externally-threaded fastener, making them highly versatile and efficient.  ### Key Features of Rivet Nuts Rivet nuts offer several advantages that make them suitable for a wide range of applications, from appliances and automotive manufacturing to office furniture, playground equipment, solar installations, electronics, boats, pools, military equipment, and even bicycles. 1. **Blind Installation**: Unlike regular nuts, rivet nuts can be installed from one side of the material, making them ideal for enclosed spaces such as tubing or areas where access to the opposite side is restricted. 2. **Threaded Insert**: They provide a robust, permanent internal thread in thin or delicate materials where a traditional bolt-and-nut combination might fail. 3. **Versatility**: Widely used across multiple industries, including automotive, aerospace, furniture, marine, playgrounds, solar installations, and military applications. --- ### Types of Rivet Nuts Rivet nuts are more versatile than self-tapping screws or pressed inserts. They are available in various materials, including steel, stainless steel, aluminum, and more. Two primary body styles include open-ended and closed-end types. Closed-end rivet nuts are particularly beneficial if you require a sealed end to prevent water or dust ingress. #### Nutsert Xtralok® The Xtralok® nutserts stand out from other round nutserts due to their unique features. These include a knurled body that locks securely into the host material, thick walls that prevent thread distortion, a low-profile wide flange for nearly flush installation, and up to 50% more material grip range compared to most competitors.  #### Half-Hex Nutserts Half-Hex nutserts take the benefits of the Xtralok® nutserts a step further by offering higher torque resistance against unscrewing and pulling out. Designed specifically for punched hex-shaped holes, they are often called hex inserts, hexserts, or hex-threaded inserts. Ideal for applications where failure isn't an option, these nutserts provide enhanced performance and reliability.  #### Full-Hex Nutsert Considered the strongest among the nutsert family, the Full-Hex Nutsert boasts superior twist resistance compared to both the Xtralok and Half-Hex nutserts. During installation, the tool collapses the nut, forming a backside flange that secures the nut to the material.  #### Smooth Body Rivnut® Rivnuts® are ideal when drilling smaller holes or working close to the edges of the parent material. As a cost-effective option, they allow you to install load-bearing threads into weak or thin-gauge materials. Predominantly featuring a countersunk profile with a lead-in chamfer for easy insertion.  #### Plus Nuts Designed for lightweight materials like plastics, fiberglass, and thin steel sheets, Plus Nuts provide a load-bearing, captive solution. With a greater material grip range than other rivet nut types and improved tolerance for oversized holes, they resemble a Byzantine cross on the blind side after installation.  #### Jack Nuts Jack Nuts or J Nuts are threaded inserts used for non-load-bearing applications. Upon installation, their slotted sleeves collapse into a propeller-like shape, gently gripping the inside of the mounting surface to create a secure set screw or bolt anchor point.  #### Well Nuts Well nuts are essentially rubber bushes with a concealed brass nut at one end. Featuring a flanged side and a barrel body inserted into a matching-sized hole, they excel at weatherproofing and isolating vibrations. Known as rawl nuts or rub nuts, Aerobolt offers a wide range of these versatile components.  #### Threaded Inserts for Plastic The A-W threaded insert is designed for installation in various materials, from plastic to plywood. Unlike conventional inserts, these expand into the material rather than outward. With a diagonal knurled thread design, they can be installed in softer materials thicker than 16mm, providing excellent pull-out resistance and sturdy internal threading for bolting applications.  #### Threaded Inserts for Timber Aerobolt offers a broad selection of threaded inserts for timber, chipboard, and MDF. Whether you're working with T-Nuts, Tee Nuts, Flange Timber Inserts, or non-flange skein nuts, Aerobolt is your go-to source for all your woodworking threaded insert needs.  In conclusion, rivet nuts are indispensable tools in modern manufacturing and construction. Their adaptability, ease of installation, and durability make them indispensable across countless industries. Whether you're working with metal, plastic, or wood, there’s a rivet nut solution tailored to meet your specific requirements.
