Threaded Rivet Nuts Solve Thin Material & Blind Fastening Problems
When looking for fastening solutions for applications in thin materials where there is access from only one side of the working material, also known as a “blind” application, threaded rivet nuts can be the fasteners you are looking for. Threaded rivet nuts, also called blind threaded rivets, blind rivet nuts and threaded inserts, have the ability to provide permanent load-bearing threads in thin materials. Rivet nuts are ideal for tubing, extrusion, and similar applications.
- Made from aluminum, brass, steel or stainless steel
- Use in place of tapped holes, weld nuts, rivets, self-drilling & tapping screws
- Only need access from “front” side of the workpiece
- Provide strong permanent metal threads in metal or plastic materials
- Can be installed in materials as thin as 0.020″ / 0.50mm
- Help promote thinner and lighter product designs
Threaded Rivet Nut Classifications
Threaded rivets nuts can be classified into two basic groups – Standard Thread Rivet Nuts & Heavy-Duty Threaded Rivet Nuts
Standard Rivet Nuts: Are designed for most standard blind fastening applications that require permanently installed threads.
- Available in unified and metric thread sizes #6-32 to 1/2″-16 and M4 thru M10
Heavy-Duty Rivet Nuts: Are designed for more demanding, high-performance blind fastening applications that require permanently installed threads. Heavy-duty rivet nuts feature heavy-duty head and sidewalls.
- Available in unified and metric thread sizes #4-40 to 1/2″-13 and M3 thru M12

In addition to the wide variety of blind rivets, our new rivet nuts & inserts also come in the most popular styles and sizes. Finally, to be sure your riveting applications are all properly installed, you will want to check out one of our manual or powered riveting tools. These high-quality riveting tools are ergonomically designed to help make your job easier than ever.
New Blind Rivet Lines
Blind rivets are designed for fastening materials together when you only have access to one side of the part or structure. Important factors you need to take into consideration when choosing the rivet for your next job include: grip range, shear strength & tensile strength.
- Grip Range: the minimum and maximum thickness that the rivet is intended to hold together once installed.
- Shear Strength: the maximum load that can typically be applied to the rivet that can be supported prior to failure and fracture.
- Tensile Strength: the maximum tension applied load that can typically be applied to the rivet prior to failure and fracture.
There has recently been an increase in the use of structural hollow sections as columns in multi-story construction projects. This increase is due to the aesthetic, economic and structural performances that these hollow sections can provide for for engineers. The only downfall to this type of construction is the inability to access the interior of the sections to allow for the tightening of a standard bolt. Due to this, there was a need to develop a blind fastening solution that will ensure a structurally sound connection.
The BoxBolt® is a convenient & reliable blind fastening solution for connecting to hollow sections of steel or where access is restricted to one side only. The BoxBolt® is fully tested and approved for us with rectangular, square and even circular hollow sections. Featuring a hexagonal head design, that aids in the installation process. The hex head allows it to be held in place with an open ended wrench, while the core bolt is being tightened by a torque wrench. As the core bolt is being tightened, the threaded wedge is drawn up inside the body, expanding the fins, creating a secure connection.
*You can use the one piece accessory called the BoxSok™ when installation time is at a premium.

- Hot Dip Spun Galvanized to BS EN ISO 1461
The BoxBolt® is approved for use by Lloyds Register (LR) type approval and the Deutsches Institut fur Bautechnik (DIBt) to give the specifier and user total confidence.
Hole Dimensions and Positioning
The loads stated above are based on the LRFD (Load & Resistance Factor Design) method recommended by the AISC for bolted steel connections. This uses a factor of 0.75 of the ultimate load and therefore equates to a 1.33 to 1 factor of safety that we have applied to our published loads above. The overall strength of the connection is governed by the strength of material our BoxBolt is connecting into; therefore, this should be checked for structural capacity by a structural engineer.
Approvals – The published loads are taken from physical testing in hollow structural section which are then verified by Lloyds Register Type Approval. The BoxBolt is also tested and approved by DIBt (Deutsches Institut fur Bautechnik) which complies with the DIN 18800 and Eurocode 3 design methods for bolted steel connections. A design guide and calculator is available when using these methods. Please ask our technical team for more information.
