Why Use Rivet Nuts for Sheet Metal?

Thin sheet metal can be difficult to tap because there is not always enough material to form a strong thread. In these cases, rivet nuts are a common choice. They provide an internal thread for bolts and screws without the need to weld a nut onto the panel.

A rivet nut for sheet metal can be installed from one side, which is useful when the back of the panel is difficult to reach. It is widely used in metal enclosures, cabinets, appliances, and other sheet metal products.

How Rivet Nuts Work in Thin Sheet Metal

A rivet nut is placed into a prepared hole and installed using a rivet nut tool. During installation, the back of the body is compressed and forms a bulge behind the sheet metal. This holds the rivet nut in place and leaves an internal thread for fastening.

Unlike tapping directly into thin metal, this method does not rely on the panel thickness to provide the thread. It is also useful for assemblies that may need to be taken apart for repair or maintenance.

Common Applications of Sheet Metal Rivet Nuts

Rivet nuts are used in many products made from sheet metal. They are often found in parts where screws or bolts need to connect panels, brackets, or other components.

Some common applications include:

• Electrical enclosures: For attaching covers, mounting brackets, and internal parts.
• Home appliances: For fastening panels and components in ovens, washing machines, and other appliances.
• Automotive parts: For connecting metal panels, interior parts, and brackets.
• Metal cabinets and racks: For mounting accessories and joining sheet metal parts.
• HVAC equipment: For fastening housings, panels, and ductwork components.

What to Check When Choosing a Rivet Nut for Sheet Metal

Before ordering rivet nuts, it is important to check the sheet thickness and the dimensions of the installation hole. These details affect whether the rivet nut can be installed properly.

• Grip range: Choose a rivet nut that matches the thickness of the sheet metal.
• Thread size: Check whether you need a metric or inch thread and make sure it matches the bolt or screw.
• Body type: Round, knurled, and hex body rivet nuts are available. The right choice depends on the hole design and the required resistance to rotation.
• Material: Steel, stainless steel, and aluminum are common options. Consider the working environment and corrosion requirements.
• Hole size: Follow the recommended hole diameter. A hole that is too large may cause the rivet nut to spin, while a hole that is too small can make installation difficult.

If you are selecting a rivet nut for a new project, checking the drawing and actual sheet thickness before ordering can help avoid fitting problems.
