What is a Rivet Nut and how to use it?

Introduction

Rivet nuts, also known as blind rivet nuts or threaded inserts, are fasteners that can be installed into a workpiece from only one side. They are used in a variety of applications, especially in situations where it is difficult to access the back side of the workpiece. They are commonly used in the automotive, aerospace, and construction industries, as well in household appliances and furniture.

How to Install a Rivet Nut?

Installing a rivet nut is a straightforward process, but it does require some specialized tools. The first step is to drill a hole that matches the diameter of the rivet nut. Once the hole is drilled, insert the rivet nut into a special tool designed for installation, such as a nutsert tool. The tool compresses the rivet nut and then pulls it through the hole, causing it to expand and form a tight grip on the workpiece. Once the rivet nut is installed, a threaded fastener can be screwed into it just like any other threaded hole.

Types of Rivet Nuts

Rivet nuts come in a variety of shapes and sizes, depending on the application. Some common types of rivet nuts include: - Open end: These rivet nuts have a hole through the center and do not have threads on the closed end. They are commonly used in applications that require a flush mount. - Closed end: These rivet nuts have threads on both the open and closed ends. They are used in situations where high pull-out strength is required. - Knurled: These rivet nuts have a knurled body that provides excellent resistance to rotation. They are commonly used in applications that require high torque resistance.

Conclusion

Rivet nuts are an excellent alternative to traditional threaded fasteners when it is difficult or impossible to access the back side of the workpiece. They come in a variety of shapes and sizes and can be installed using specialized tools. It is important to choose the right type of rivet nut for the application in order to ensure a secure and reliable connection.
