Jack Nut (also known as insert nuts, clinching nuts, or threaded inserts) are a type of fastener. They can create strong connections in materials like sheet metal, plastic, fiberglass, and other softer or thinner materials. These materials cannot hold threads on their own, making jack nuts an ideal solution.
Jack nuts are often provide a durable threaded insert for screws, bolts, or other fasteners. This enables secure attachment points in thin or weak materials.
Key Features of Jack Nuts
1. Flanged Body
The flanged body of a jack nut enhances its functionality by improving load distribution, preventing material damage, and providing stable installation. Additionally, it plays a crucial role in ensuring the nut remains securely fixed in place after installation. As a result, it is ideal for a wide range of applications in thin or soft materials.
2. External Serrations or Knurling
The outer surface of jack nuts is typically serrated or knurled. These features help the nut grip the material tightly, preventing rotation or loosening after installation. They provide a secure grip in the base material. This feature ensures the nut stays in place under stress, preventing loosening, shifting, or rotation. Moreover, jack nuts contribute to ease of installation and long-term durability in various materials. As a result, they are ideal for applications where strong, lasting threaded connections are needed.
3. Internal Threads
Jack nuts come with internal threads, which allow for the attachment of screws, bolts, or other fasteners. The internal threads are designed to accept standard screws or bolts, creating a secure attachment point in materials that cannot be directly tapped. Additionally, jack nuts ensure compatibility with standard screws or bolts, enhance the durability of the connection.
4. Installation Process
They are installed by using a special tool that compresses the nut’s body, causing it to expand and anchor itself firmly in place. The external serrations or knurls ensure the nut stays in position.

Rivet Nuts are a type of fastener. They can create a strong, durable threaded connection in materials that cannot hold threads on their own. These include materials like sheet metal, plastic, or composite materials.
In fact, rivet nuts are commonly used in applications where a strong, secure threaded insert is needed but where traditional threading is not feasible due to the material’s thickness or softness. The installation principle works by expansion or deformation within the base material. As a result, the expansion provides a secure, reliable thread for attaching bolts, screws, or other fasteners.
Types of Rivet Nuts
Rivet nuts are available in various materials and designs to suit different applications. The most common types include those made from different materials, such as steel, aluminum, and stainless steel, as well as various head designs, such as countersunk and flat head rivet nuts.

Design and Structure Comparison
Jack Nuts:
Jack nuts typically have a flanged body with internal threads and external serrations or knurls. As a result, the serrations help anchor the nut securely to the base material once installed. In addition, the flange is usually thin and designed to be compressed during installation, gripping the base material tightly.
Rivet Nuts:
Rivet nuts also have a flanged body and internal threads, however, the flange is generally thicker compared to jack nuts. Furthermore, they usually have a smooth outer surface or mild knurling to help anchor them in place. During installation, it is designed to be swaged (or deformed), expanding the body to form a strong mechanical grip on the base material.
Installation Process Comparison
Jack Nuts:
Jack nuts are typically installed using a clinching tool or a manual tool that compresses the body of the jack nut. As a result, this causes the nut to grip the material and form a secure connection.
Rivet Nuts:
Rivet nuts are typically installed with a rivet nut tool. This tool can be manual, pneumatic, or hydraulic. It works by applying a radial force to the body. Consequently, this force causes the body to expand. The expansion creates a strong grip inside the material. Moreover, the flange of the rivet nut acts as a stopper. This ensures the nut is securely fixed in place and prevents excessive deformation of the material.
Material Compatibility and Application Comparison
Jack Nuts:
Jack nuts suit thin or soft materials like plastic and sheet metal, where threads cannot be directly tapped. Additionally, people commonly use them in applications where aesthetic appearance matters, as they offer a clean, flush installation. Thus, you often find jack nuts in electronics, furniture, automotive, and consumer products that require moderate strength.
Rivet Nuts:
In contrast, rivet nuts work well in heavier applications that need a more robust threaded connection. Consequently, they suit thicker materials like steel or aluminum. As a result, industries like automotive, aerospace, construction, and machinery widely use rivet nuts. These industries demand connections that can endure high stress, vibrations, or heavy loads.
Jack Nut vs Rivet Nut: Conclusion
- Jack nuts are ideal for light-duty, aesthetic-sensitive applications with thinner or softer materials.
- Rivet nuts are better for high-strength, heavy-duty applications, particularly in thicker or industrial-grade materials where durability and performance are critical.
