What is a Rivet Nut?

A rivet nut is a special type of threaded fastener. It is a device that acts to form a threaded hole and provide a threaded connection in a thin plate, pipe or other thin material.

The rivet nut is similar in appearance to a nut, but the rivet nut is threaded on the inside. It has a flat bottom and an open top with grooves and indentations on the bottom that increase the resistance to rotation forces with the material.

Rivet nut can be made in different fabrication materials such as steel, aluminum, stainless steel, copper, carbon steel, etc. depending on your project needs. They come in a variety of different sizes and thread specifications, which you can customize from the rivet nut manufacturer according to your specific needs.

How do Rivet Nuts Work ?

The essence of the rivet nut is to make a tight connection by expansion. It is not possible to use bolts or screws when making fastening connections in thin plates. Therefore, a rivet nut is required to provide a connection point for bolts or screws.

The rivet nut is threaded by applying pressure to deform the rivet nut horizontally.The youtube video below shows you in detail how do rivet nuts work.

The rivet nut application consists of the following components: the rivet nut, the rivet nut tool, the substrate on which the rivet nut is to be installed, the bolt or screw. The rivet nut connects the parts by tightly joining the bolts together through the mechanics of the threads inside it. The rivet nut is pulled using a screw on a rivet gun, which compresses the rivet nut longitudinally and creates a raised deformation at the top, thus clamping the riveted joint.

What are the Benefits of Rivet Nuts?

Rivet nuts provide a fast, reliable and cost-effective solution for connecting sheet metal parts to each other. Rivet nuts have many advantages over nuts and bolts.

Seven Advantages of Rivet Nuts:

  • Strong and reliable threaded connections provide a durable and dependable anchor point for bolts or other threaded fasteners.
  • Ability to distribute the load over a large surface area. Prevents material deformation or damage compared to conventional nuts.
  • Rivet nuts can be assembled significantly faster than methods such as welding or crimping. It can effectively reduce production time and cost.
  • Rivet nuts create a flat, low-extension appearance on the surface of the material. Improves the overall aesthetics of the finished product.

Provide Suitable Holes for Rivet Nuts

In order to ensure the tightness of the rivet nut connection, in general, the holes in the plate should be 1mm more than the outer diameter of the rivet nut. that is to say, when the outer diameter of the rivet nut is 4.7mm, the open hole should be 4.8mm. according to a large number of practice has shown that the tightness of this is the best.

The following table shows the relationship between the outside diameter of the rivet nut and the corresponding hole.

Correct Insertion of The Rivet Nut

Insert the rivet nut into the drilled hole, you need to make sure that the head of the rivet nut is flush with the surface of the material. The riveting is then accomplished by means of a riveting tool so that the threaded portion of the rivet nut is fully seated in the hole.

Installation of Rivet Nuts

There are many tools for installing rivet nuts, but they are broadly categorized into three types: hand rivet nut tools, electric rivet nut tools and pneumatic rivet nut tools.

Installation of rivet nuts can be accomplished regardless of the installation tool used. Installing rivet nuts is a simple process that can be accomplished in a few easy steps.

  1. Screw the rivet nut onto the mandrel of the tool.
  2. Place the rivet nut into the pre-drilled hole. Start the tool and pull the rivet nut.
