A rivet nut, also known as a blind nut or threaded insert, is a mechanical fastener that combines the features of a rivet and a nut. Here is a detailed introduction:
A typical rivet nut consists of a cylindrical body with internal threads and a flange at one end. The body is usually made of metal, such as steel, aluminum, or stainless steel, to ensure strength and durability. Some rivet nuts may have a coating or plating to improve corrosion resistance.
The rivet nut is installed by inserting it into a pre - drilled hole in the workpiece. Then, a special tool is used to pull the mandrel (a small rod - like part inside the rivet nut). As the mandrel is pulled, it deforms the body of the rivet nut, causing it to expand and grip the sides of the hole. This forms a secure and permanent connection. The internal threads of the rivet nut allow screws or bolts to be threaded into it, providing a convenient way to attach other components to the workpiece.
Automotive Industry: Rivet nuts are widely used in the automotive manufacturing process. They are used to attach various components such as seats, interior trim, and engine parts to the vehicle's body. The ability of rivet nuts to provide a strong and reliable connection in thin - walled materials makes them ideal for automotive applications.
Electronics Industry: In the production of electronic devices, rivet nuts are used to secure printed circuit boards (PCBs), enclosures, and other components. They offer a stable and electrically conductive connection, which is important for ensuring the proper functioning of electronic equipment.
Aerospace Industry: Due to their high strength - to - weight ratio and reliability, rivet nuts are also used in the aerospace industry. They are used to assemble aircraft structures, attach panels, and secure various components in place. The strict quality and performance requirements of the aerospace industry make rivet nuts a preferred choice for many applications.
General Manufacturing: Rivet nuts find applications in a wide range of other manufacturing industries, such as furniture making, metalworking, and construction. They are used to assemble products, attach hardware, and provide threaded connections in various types of materials.
High Strength: Rivet nuts can provide a strong and durable connection, capable of withstanding high tensile and shear forces. This makes them suitable for applications where reliability and long - term performance are critical. Blind Installation: One of the main advantages of rivet nuts is that they can be installed from one side of the workpiece, making them ideal for applications where access is limited. This saves time and effort during the installation process, especially in hard - to - reach areas.
Versatility: Rivet nuts are available in a variety of sizes, thread types, and materials, allowing them to be customized to meet specific application requirements. They can be used with different types of screws and bolts, providing flexibility in design and assembly.
Good Vibration Resistance: The expanded body of the rivet nut creates a tight fit in the hole, which helps to prevent loosening due to vibration. This makes them suitable for applications in which the connected components are subject to dynamic forces.
